Missable Trophies: Aside from the Story Related trophies, everything
Minimum Playthroughs Needed: 3
Difficulty Affects Trophies: Yes
Glitched Trophies: N/A
1) Play and finish the game for the first time.
With other games, you might usually start off on the hardest difficulty setting to get rid of the difficulty related trophies out of the way. Unfortunately for this game, this won't the case; they don't stack. Completing the game on Legion Hunter(Hard) will only unlock the trophy for completing the game on Hard, but not the other two. You'll have to play this game a total of three times if you want to platinum it. That said, I recommend you at to play on Normal or Hard on your first playthrough for the most enjoyment.
You will earn all story related trophies on your first playthrough, along with most if not all weapon and skill based trophies. Note that weapon upgrades are automatic and part of the story, so if you didn't manage to get enough kills with a particular weapon prior to the upgrade, you'll have to try again on another playthrough. Just something to keep in mind.
Another thing to note, is the Red Gems. Don't worry about finding all of them on your first time through but instead, take note of where you found them for subsequent playthroughs. Though you can if you want to find all of the Red Gems if possible, its not recommended, especially if you're playing on Normal or Hard. The higher the difficulty you're on, the more expensive it is sold from Christopher.
For a list of locations of the Red Gems scattered across the chapters, refer to the Red Gems Location Guide. For a few White Gem farming locations, refer to the High in Las Vegas trophy.
2) Finish the game a second time.
Begin your second playthrough on another difficulty. If you missed a few of the weapon and combat related trophies, now would be a good time to do them, so you don't have to worry about them on your final playthrough.
If you're playing on Easy, now would be a good time to find all of those Red Gems scattered across the game. Note that you'll need to perform a total of 80 upgrades; 36 Red Gems can be found throughout the game, the rest must be bought from Christopher. As mentioned before, the higher difficulty you're playing on, te more expensive it will be to buy them.
3) Finish the game for the third and final time.
On your third and final playthrough, pick the only difficulty setting left you have to play. This would be your final chance to clean up anything you may have missed.
[PS3T Would Like to Thank BreadSkin for this Roadmap]
Story Progression in Act 1 - Chapter 1 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 1-1.
After the initial cutscene, you'll make your way back to your apartment only to realize your girl Paula, is in danger. Another cutscene ensues and your apartment will get ambushed by demons. Serving as an in-game tutorial at the same time, simply follow the game's instructions and defeat them as they come.
After jumping your way to the Underworld, you'll be introduced to Johnson. You'll finally be given the option to make a save file and choose the difficulty setting. This trophy will unlock during this time.
Story Progression in Act 2 - Chapter 1 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 2-1.
An introductory chapter of sorts, you'll learn about how to survive in the Underworld throughout the chapter. First and foremost, is the importance of our demon friend, Willy (aka. One Eyed William). As well as lighting up areas for you, he'll be serving as your checkpoint - though the use of his big smoky dumps.
In addition, during this chapter, you'll learn the importance of the following as well as unlocking their entry in the Johnsonpedia:
Vending Machines and Red Gems
Darkness Vines (aka. Demon Pubes)
White and Red Gems
Blue and Red Cores
At the end of the chapter, you'll be introduced to the Darkness Hand. These enemies will constantly release darkness into the area until you defeat it. To stop it, shoot the dark core in the back of this area to open the vine covered gate, then its just a matter of slowly making your way through more gates until you reach a ladder. Climb up to the ledge above, then shove your Johnson into the Hand.
Story Progression in Act 2 - Chapter 3 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 2-3.
During this chapter, you'll unlock the following entries in the Johnsonpedia:
This will also be where you're introduced to Christopher, a half demon half human, your merchant in the game. Next to Vending Machines, this will be where you'll be spending those White Gems.
In the final area of this chapter, you'll get to have some fun swinging on a chandelier. Those phallic like objects you see on the side of the walls? Swing your chandelier towards them to destroy the core to slowly make your way upwards.
Story Progression in Act 3 - Chapter 2 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 3-2.
Another straightforward chapter. This will be the chapter where you'll encounter the Big Demons, Hellmonkeys, with flashlight for eyes for the first time. To quickly take them out, rather then shoot out their eye, blind them by engulfing the area in darkness if possible instead.
You'll also run into your first Cyber Demon. Strategy wise, they're not much different than the regular Demons, only now they have armor covering their flesh. To take them out, unload a sticky payload from your Hot Boner to break their armor, then finish them off now that their flesh is exposed.
Story Progression in Act 4 - Chapter 2 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 4-2.
Arguably the second best thing in the entire game, besides the previous chapter. What's a Suda51 game without a section like this? Everything you've learned applies to here as well, only now you do so in side scrolling form.
Aiming is done with the , shooting with (holding it to trigger rapid fire), for Light Shots. Note that you are able to aim upwards and downwards, but you not towards the left. If possible, try and collect all 50 Gems for a Red Gem as a reward.
Story Progression in Act 4 - Chapter 3 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 4-3.
To defeat the teleporting demons, you must blow up the poles around the library with your Hot Boner. Once you've unloaded your sticky hot load into each stone, you'll nullify the electricity surrounding their bodies, allowing you to finish them off. Back away from them as soon as you do though, as they'll blow themselves up, electric force field style.
You'll eventually stumble upon a puzzle. You'll need to rearrange the shelves with your Light Shot, so that the balcony from the right connects to the left. The opening for the balcony to your right is on top, and the opening for the balcony on your left is on the bottom.
Story Progression in Act 4 - Chapter 5 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 4-5.
Your new weapon, The Dentist will prove to be very useful against those Masked Demons. You'll also run into a new enemy, armored demons that burrow themselves underground. Wait for them to come spinning at you then dodge; they'll knock themselves over and expose the core on their chest. Destroy the core, preferably with the Skullfest 9000 to make quick work of them.
Story Progression in Act 5 - Chapter 1 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 5-1.
After defeating the electrified crazed demon and some more enemies, you'll need to open a vine covered gate to proceed. Open the baby gate in the back, then turn around. Notice how the red core is inside the green barriers? Use your newly acquired Skullblaster and launch one from within the darkness to destroy the core.
You'll also run into your first Blindness Hand. Unlike the Darkness Hands, they can only be defeated by destroying the big red cores on the ground located somewhere in the stage. Follow the blue veins to get to them.
Story Progression in Act 5 - Chapter 2 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 5-2.
You'll be fighting many enemies for the first part of this chapter, so do whatever you do best and take them down. Make use of the Barrels of Light outside if you need them. 2 of those Generator Demons as I like to call them will eventually spawn. The best way to take them out is to fire a Hot Boner at them then blow that up to destroy all the red vials on their backs.
The second part, requires you to move Tetris like blocks in order to progress. For the record, you can move them left and right, but also upwards and downwards. There's only one possible path you can take anyways, so solving them should be easy enough.
Story Progression in Act 5 - Chapter 3 (any difficulty setting)
Story related. Cannot be missed. Unlocks upon completing Act 5-3.
The first part of this level is pretty straightforward; defeat enemies, go up a level in the tower, repeat. The second part however, puts you into a little maze of some sorts. The "maze" is actually pretty linear, so make your way through each darkness portal until you find the strawberry. Open the baby gate, go up an elevator to complete the level.
Story related. Cannot be missed. Unlocks upon defeating the boss in Act 2-2.
Your first boss encounter in the game, and what better way to do so in a Mexican Marketplace!
Geroge will be chasing you and will be invulnerable, so your job is to run away from him, jumping over booths and stands. So how do you fight back? Well damaging him is simple. See those Barrels of Light you keep running accoss? Blow one up when he's standing next to one to knock him down, and he'll expose the weakpoint on his head. Unload a series of shots into his head before he gets back up. He'll run off, but not without ripping off a nearby Goat Head, covering the whole area into darkness. See that pillar of red light you see in the distance? That's where George is hiding. Make your way through the darkness, picking up Red Hearts, and when you finally find him behind a stand, fire a Light Shot at the Goat Head to light things back up.
Repeat this 3 times to finish the Harmonica playing lieutenant. You'll gain your first Blue Gem upgrade as well as your trophy.
Story related. Cannot be missed. Unlocks upon defeating the boss in Act 2-4.
George wants revenge from the last battle, and what better way to do so by coming back to challenge you dual wielding a set of spears. Did I mention he's also riding a horse?
First Phase Geroge will start things off by having his horse produce a vortex of darkness - through his butt. Your job is to head into the darkness and shoot the core on George's back while he runs around the courtyard. Once you nail in a sucessful hit, he'll collapse along with his horse exposing the red cores on the horse's stomach. Unload some bullets onto it before he gets back up. He'll then jump on top of the fountain and attempt to hurl spears at you. Dodge them, then shoot the red core on the horse. Repeat until his horse is defeated.
Second Phase With his horse defeated, he'll now grow triple his size. See those red cores all over George's body? His only attack will be a large stomp, so simply avoid it by dodging and shoot out the cores as you do so. Destroying all the red cores will once again envelop the whole place in darkness. Shoot the tentacles coming out of his stomach before you succumb to the darkness to finally defeat him.
Story related. Cannot be missed. Unlocked upon completing Act 3-1.
At the end of Act 3-1, you'll be ambushed by waves of Demons, followed by your first encounter with Armored Demons. Defeat them, and Maras Grim, the first Sister Grim, will make her appearance.
As with most bosses, she'll be invulnerable until you stun her. Avoid her scythe attacks until she does an overhead slam and pounds her scythe to the ground, resulting in the battlefield coveried in darkness. Instead of lighting up the Goat Head in the back, find her amidst the darkness and fire a Light Shot at her. Be quick though, as she'll be coming towards you. She'll be stunned, exposing the red core on her chest. Get in a few bullets in her chest, then simply repeat this process until she's defeated.
Story related. Cannot be missed. Unlocks upon defeating Kauline Grim.
After running away from a crazed out Paula, you'll fight the second Sister Grim, Pauline.
As with the previous battle with the sister, the same strategy still applies. Dodge her attacks, and wait till she does a overhead slam and engulfs the arena in darkness. Find her before she finds you, and stun her with a Light Shot. She'll expose a red core in her chest. After you destroy the red core on her chest once, she'll change things up by making multiples copies of herself. To find the real one, look for the one with the red core.
Story related. Cannot be missed. Unlocks upon defeating Elliot.
Well that was unexpected, kind of.
First Phase The entire boss battle will take place on this long bridge. Wait till "Stinky Crow" swoops back down towards the bridge so you can get some clear shots in. When he takes a huge breathe and tilts his head backwards, thats your cue to dodge his spike attack. Occassionally, he'll shoot two red feathers onto the bridge, turning everything into darkness. To get rid of it, fire a Light Shot at it to dispel it.
Second Phase Once you've destroyed the core on his chest, he'll come back up, this time with a few new attacks. He may now hurl boulders at you, which will knock you off if you get hit. If that happens, repeatedly press to get back up. Occasionally, he'll now send smaller versions of himself to the lamp on the bridge, shadowing his figure. Get rid of them by using the torch. His weakpoints are now on his wings.
Third Phase Finally, he'll now attack you on the brdige. Open up his stomach with a Light Shot to expose the red core. Dodge his claw attack. When he flies overhead you, press to do a 180 turn.
Story related. Cannot be missed. Unlocks upon defeating the boss in Act 4-3.
The Eldest sister of the Sister Grim, she'll prove to be quite a challenging boss fight compared to the previous ones.
She will wield not one but two scythes, and will have 3 different attacks:
She'll throw a scythe at you one at a time that will home in on you one by one
She'll throw both her scythes in the air splitting into 6 different ones, and hurl them towards you
A shockwave attack
In order to damage her, you'll need to shoot at the red core on her head. Once that's destroyed, she'll spill out darkness, and expose another red core on her torso. Damage the core on her chest as much as you can, preferably with The Teethgrinder, before dispelling the darkness by using the Goat Head in the back.
Story related. Cannot be missed. Unlocks upon defeating the boss in 4-6.
Not what I expected, but this boss battle will take place entirely in the form of a side scroller.
Shoot the three red cores on Justine's mask, avoiding the green acid she constantly releases over top of you from the machine on her back. Note that you can destroy the acid drops, you don't have to just dodge them. Once the three cores are gone, she'll reveal yet another mask, which can only be damaged by Light Shots. Destroy that, and she'll finally reveal her face. She'll change things up a notch, grasping you with her hands. This attack is unavoidable, so just keep shooting at her head until she throws you away. Occasionally, a Teether or the Big Boner might appear on the top of the screen to help your aid. Simply keep shooting at her and she'll eventually go down.
Story related. Cannot be missed. Unlocks upon defeating the boss in Act 5-4.
And what better way to finish things off than on the top of tower.
Fleming's attacks will consists of the following:
A laser beam, his eyes will glow and tilt back before firing
A shockwave attack, he'll twirl himself into the air before slamming his "instrument" down on the ground
Occasionally, he'll open up his cape revealing either Paula (don't shoot her), or spew darkness into the area. To counter the darkness, shoot the Goat Head chandelier on top of you.
To reveal Flemings' weakpoint, keep shooting at him, preferably with the Skullblaster to conserve your ammo, until you crack his armor. He'll stop attacking, stunned, which you can then fire a Hot Boner at him to destroy it, splitting his body into three parts. While his body parts circles around the area attempting to regenerate, you should notice that one of his body parts will be glowing red. Shoot at it until he regenerates, then repeat the process until you've dealt enough damage to that part of the body. The trick to damaging the body parts while they're circling around the area, is to use The Dentist's homing capabilities, staying as far back as possible and keeping your crosshair on it until it turns red.
As the battle progresses, he'll begin to use different attacks as well:
A second laser beam attack, that will sweep around the arena and follow you
He'll produce a green force field, which you must fire a Demon Skull into one of the three openings to break it
He'll reveal a dark hand under his cloak, which we'll imprison you in area filled with darkness if it was able to grab you. To get out, blow up one of the three doors in the back with your Hot Boner until you find the exit
Additionally, the Goat Head chandelier will also move swing faster and faster, making it difficult for you to get a clear Light Shot at it.
Weaken each of the three body parts of Fleming to finally finish him off.
Difficulty in this game is split into the following:
Lemon Hunter - Easy
Demon Hunter - Medium
Legion Hunter - Hard
Unlike other games, the difficulty related trophies in this game don't stack, so you'll need to complete this game a total of three times. There also isn't an New Game+ option unfortunately, so any upgrades you've done on previous will not carry over; you'll be starting from scratch for each playthrough.
Simply beat the game in the difficulties listed above to unlock their respective trophy. The trophies will unlock during the credits.
Aside from damage upgrades, don't upgrade your arsenal unless you really need to, particularly your health or a weapon's ammo capacity. Upgrading your health will automatically heal you to full, and ammo for weapons. Very useful if you want to save up on Drinks or White Gems
Unless you're in desperate need for alcohol, save all your White Gems for Red Gems. You'll need all the extra money you can get especially if you're working towards High in Las Vegas
Alcohol and Ammo can be found within the breakable barrels and boxes you come across in each chapter. For the sake of conserving ammo, break them open with your Hot Boner or the Light Shot
Running low on ammo? Perform a Brutal Kill instead
Weapons wise, focus on upgrading the damage before anything else. The Concusioner (and the upgrades after it) and the Torch alone will get you through most of the game
To do a Stomp Attack, shoot at a demon's legs with any gun and their legs will eventually get blown off. Follow it up when they're crawling on the ground by running up to them and repeatedly press .
Simply do this 10 times in one playthough to unlock this trophy. Stomp killing demons will earn you more White Gems compared to a regular kill, so even after you've unlocked this trophy, it wouldn't hurt to perform it still for some extra Gems.
The Teether - Unlocked at the end of Act 2-2, selectable via
The Teether is your machine gun in this game. Johnson will be covered in blue flames when selected. The Teether's source of ammo are Demon Teeth, which can be found in blue chests located throughout the chapters or purchasable from Christopher as with other weapons.

The Skullcussioner - Unlocked at the end of Act 2-4, selectable via
The Cushioner is your shotgun in this game. Johnson will be covered in green flames when selected. The Teether's source of ammo are Demon Skulls, which can be found in green chests located throughout the chapters or purchasable from Christopher as with other weapons.
Simply kill 30 enemies with The Skullcussioner to unlock the trophy.
The Hot Boner - Unlocked at the end of Act 3-1, selectable via
The Hot Boner will serve as an upgrade to the previous version. You'll now be able to lay mines with by +(Hold), which you can then blow up by shooting at them with a bullet. Like the regular Boner, Johnson will be covered in red flames when selected.
Simply kill 20 enemies with The Hot Boner by laying mines and blowing them up to unlock the trophy.
The Teethgrinder - Unlocked at the end of Act 3-3, selectable via
Replacing The Teether, you'll now be able to shoot Demon Teeth at twice the speed thanks to its multiple barrels. As with the Teether, Johnson will be covered in blue flames when selected and its source of ammo are Demon Teeth, which can be found in blue chests located throughout the chapters or purchasable from Christopher as with other weapons.
Simply kill 30 enemies with The Teethgrinder to unlock the trophy.
The Skullfest 9000 - Unlocked at the end of Act 3-4, selectable via
Replacing The Skullcushioner, you'll now be able to shoot four Demon Skulls at once by holding the fire button to load up the skulls. As with the Skullcushioner, Johnson will be covered in green flames when selected and its source of ammo are Demon Skulls, which can be found in green chests located throughout the chapters or purchasable from Christopher as with other weapons.
Simply kill 40 enemies with The Skullfest 9000 to unlock the trophy.
Unlike the other weapons, you'll only get to use the Big Boner in Act 4-1.
A sort of mini-game, you'll have several streets to take care of. Hellmonkey's will slowly make their way towards you. Switch screens with and , and to aim your laser sight around. The easiest way to do this is to move your laser sight in a position where their heads will move towards. Fire once they're within range. Note that you don't necessarily have to shoot them dead on in their heads, as long as the shot was hit somewhere in the head area, it'll count. You'll know its a successful headshot when you see the blood effect and they'll die in one hit. Though you'll get 3 chances to earn this trophy, try to earn it in the first section as things aren't as chaotic.
Take your pole for a stroll and get 5 head shots in a row with the Big Boner, and the trophy will unlock. Shame you don't get to keep it (for obvious reasons).
The Dentist - Unlocked at the end of Act 4-4, selectable via
Replacing The Teethgrinder. Topped with even more insane firepower, your bullets will now have homing capabilities. Simply aim at enemies without shooting and they'll automatically be locked on, then hold the fire button to unleash. As with the Teether, Johnson will be covered in blue flames when selected and its source of ammo are Demon Teeth, which can be found in blue chests located throughout the chapters or purchasable from Christopher as with other weapons.
Simply kill 50 enemies with The Dentist to unlock the trophy.
The Skullblaster - Unlocked at the end of Act 4-6, selectable via
Replacing The Skullfest 9000, you'll now be able to shoot one big Demon Skull, grenade style. Hold the fire button to spawn four skulls, then hold it even longer co combine them into one. As with the Skullcushioner, Johnson will be covered in green flames when selected and its source of ammo are Demon Skulls, which can be found in green chests located throughout the chapters or purchasable from Christopher as with other weapons.
Simply kill 50 enemies with The Skullblaster to unlock the trophy.
As the trophy description says, you'll need to perform 5 head shots in a row with any weapon except the Big Boner, so use another weapon such as The Teether. You'll know you've performed a head shot when a slow motion camera effect triggers. If you shot a Demon's head off but the camera effect didn't occur, it won't count. Note that you can miss a shot and it'll still count towards your five in a row, provided your bullets don't hit the Demons anywhere else.
If you want to do it early on, you can do this in the very beginning of the game, when your apartment gets overrun with demons. Things won't be as chaotic and they'll slowly come at you, so take your time. Though keep in mind there's only a limited amount of demons before the game automatically continues.
The best place to earn this is during Act 3-2. After facing your first Cyber Demon, make your way back towards the bridge. The bridge will collapse and you'll fall into the water. In order to progress, you'll need to find Paula who is drowning somewhere in this body of water. Instead of of looking for here, run around until Demons start coming towards you; they will be coming towards you in groups of three. Demons will keep spawning in this area until you reach Paula so keep practicing your head shots until you get your 5 in a row.
A little trick I learned to use, was to wait for one of them to come at you with a slash or a jump kick. Dodge backwards then quickly aim with your weapon. They should stay still long enough for you to aim at their head before they attack again. Try your best to keep your distance, but not too close.
OR, if you're really having trouble, you can abuse this cheap trick during Act 3-2. Should be self explanatory enough:
Credit goes to gmurda33 from our sister site for posting this original method.
Perform five head shots in a row, and the trophy will pop.
This is one of the harder trophies in the game next to Nasty Headache.
As per the trophy description, you'll need to shoot off a Demon's legs then quickly kill it with a head shot while it's still in the air. Note that the slow motion camera effect does not and probably won't trigger; so that's not required for the trophy. An easy way to earn this is with The Teethgrinder. Get close, but not too close, and fire at a demon's leg, and when you shoot them off, aim upwards just a bit towards their head while they're still in the air. With any luck, you'll shoot off their head, earning you the trophy.
There's no real strategy to this trophy other than to practice, practice, practice until you get it. Once you're able to pull it off, the trophy will unlock. Be glad you only had to that once!

Barrels of Light are those barrels leaking with light you run across throughout the game. They contain pressurized light, therefore making them highly explosive.
Your very first chance to earn this will be during Act 2-1, when you're first introduced to the Barrels of Light. After opening the gate covered with Darkness Vines (aka. Demon Pubes), you'll be locked inside a small courtyard and be pitted against four demons. Shoot the Goat Head in the back to light back this place up, then lure the demons beside the barrels. Blow up one to get rid of the darkness covering them up, then another to finally finish them off. If you killed 3 enemies at once, you'll unlock the trophy.
A much easier way however, is during Act 2-3. After meeting Christopher, you'll be introduced to the Sushi Lamp. Light Shot it then follow him around the corner, and you'll face 3 demons. Shoot the Barrels of Light behind them.
Video from the always helpful, Achievement Hunters At the 1:10 - 2:18 mark
Your Boner will get an automatic upgrade to the Hot Boner at the end of Act 3-2. Serving as your secondary fire, to use it, aim with the as usual and hold . Releasing the trigger will produce a mine, which you can then fire a bullet to it to make it explode.
Earning this trophy is not a matter of difficulty, by finding a place where five enemies will spawn at once at the same time. In this case, you'll reach one of these rare occurances near the end of Act 3-3. Shortly after earning the Skullfest 9000, go through the gate and you'll see five to seven demons coming out of a cave. Place a well aimed sticky load, and blow it up hopefully killing at least 5 enemies in the blast.
Because enemies take fewer hits to die in lower difficulties, consider doing this trophy on Demon Hunter (Normal) or lower.
Healing items in this game takes the form of booze. Contrary to real life, drinking vodka or other forms of alcohol will heal you in the Underworld.
Hot Sake - + Tequila - + Absinthe - +
After being introduced to your first bottle of booze in Act 2-1, they'll start appearing throughout the game for you to collect. To chug a bottle, hold and select a drink of your choice with the D-Pad. Pressing again and you'll knock back another drink.
Simply collect three bottles or more and chug them down in a row to unlock the trophy. Note that you are not required to be damaged for this to count.
White Gems serve as the currency in this game. Those vending machines and items on Christopher you run into each chapter? You use them to buy this.
As the description says, you must have 300 or more White Gems in your inventory at once in order to unlock this trophy. If you've been saving up since you started up the game, you'll unlock this near the beginning of Act 3-1.
"Performance Enhancers", as Johnson likes to call them are what is used to upgrade Garcia's and your weapon's performances. Red Gems can be found throughout the course of the game, as well as purchased off from Christopher once you meet him.
Note that the trophy description is a bit misleading. Finding all of the Red Gems scattered throughout the game will not unlock it. In order to unlock it, you need to upgrade everything through the use of 80 Red Gems.
You will need a total of 80 Red Gems in order to upgrade everything. However, only a total of 36 Gems can be found scattered across the chapters, so you'll need to get the rest by buying them off of Christopher. Note that Christopher will have an infinite supply of Red Gems for you to purchase, so don't worry if you missed a few.
For each of the following locations, you can choose to earn as many White Gems as you can or keep going until you hit 999 (max amount you can carry at one time). Kill your enemies by shooting their legs off followed by a stomp attack to earn the most amount of Gems possible on each defeated enemy. There will be at least one ammo box for you to use to replenish your ammo.
Note that should you die during farming, any Gems you obtained will be gone and will have to be earned again since nothing will be saved until you reached the next checkpoint.
Act 2-3 Shortly after meeting Christopher, you'll come across a graveyard in which you'll be introduced to your first three-headed demon. Enemies will constantly spawn from the darkness until you destroy the three red cores around it.
Act 3-2 Same location as suggested for Nasty Headache.
Act 4-3 You'll run into a one of a kind armored demon. Light Shot it until he falls down, then repeatedly mash to perform a stomp attack on it over and again for an infinite amount of White Gems, until you cap at 999 that is.
Story related. Cannot be missed. Save Paula from her anger to unlock this trophy.
First Phase Before doing anything else, grab the key in the middle, and try it on each of the baby gates until you get one open. Once that's taken care of, only then should you focus on Paula. As always, take out the weakpoints, which in this case are her wings. Cause she's moving so fast, The Dentist is very useful here. Her attacks are simple to avoid, so just keep dodging and shooting until you've weakened her wings. She'll constantly spawn enemies into the area, which you can simply kill them until she spawns another one, or just ignore them. If they're proving to be a nuisance, kill them with the Skullblaster.
Second Phase This time, the entire battle will take place amidst a infinite long corridor. Darkness will continually engulf the area behind you, so don't stop moving! Do the same thing as with the previous phase shoot at her wings with The Dentist. Avoid her attacks all the same, especially her whirlwind attack. Though it won't damage you, it'll spin you in place and cause you to face the other way.
