Complete the game on any difficulty setting once to unlock this trophy and Hardcore difficulty.

Complete the game on Zealot setting. In this setting enemies are at their toughest and ammo is very very limited compared to lower difficulties. I highly recommend upgrading your RIG Health as soon as possible, then worked on the Plasma Cutter and Contact Beam as these two weapons are absolutely crucial for the last few chapters.

Across the game you will see many Green squarish containers on the floor with small lit up lights at the corners. Press to stomp on 10 of them for useful items and this trophy. You should get it in early of Chapter 2.

Missable! You are going to need a minimum of 2 playthroughs (and NG+ to carryover stats) as there are very limited opportunities for this. On Chapters 3, 4 and 7 you will find large rectangular windows with inscriptions "Future Expansion" on them and yellow-black hazard bar on top (see Skewered in Space video for impression). Be very careful around them. When there are enemies around, shoot this window to break the glass and suck enemies into space. You will have to shoot the red triangle above the window to prevent yourself from following suit, or you'll die and the kills won't count.

On Chapter 7 use the following strategy from B0SS Zombie to obtain more kills:

You can track your progress by pressing and checking the "Trophies" option, this stat displayed is tied to your current save file. Your progress will carry forward to the next playthough only if you choose to play on New Game+.

Some enemies such as the Spitter and Stalker may appear to be crawling with their hands in certain spots of the game. For other enemies, you will need to shoot off their legs first to get them into crawling position. Scorpions at full health do not count, unless you have dismembered one of their hands and they're crawling. Press to stomp on their limbs and kill 25 them. It is advised that you freeze them with Stasis first so you can avoid damage, especially if attempting this on harder difficulties.

Hold and press on a grappable object to lift it with Kinesis. Press to fire the object on any target. You should aim to get this early in the game when enemies are relatively weak and easy to kill. You can grab anything that looks like a pole, floor mop, spikes, dead enemies' claws and the like and impale enemies with them. On Zealot difficulty it typically takes two impales to kill an enemy. You can upgrade your Kinesis-impale damage on your RIG.

Crawlers are infants with an exploding sac on their back, which you will encounter first in the Elementary School in Chapter 6, 9 and 13. It is possible to obtain this in one playthrough, but you will need to attempt this everytime you come across Crawlers. You need to aim to sever their heads or legs off, and the Plasma Cutter's ALT attack (in horizontal position) is ideal for this, as well as the Force Gun and Flamethrower.

You can either use your personal Stasis Module (press ) or grab Stasis Cylinders and fire at enemies to freeze them temporarily. While enemies are in this state, dismember and kill them for a total of 50 times to unlock this. You can track your progress by pressing and checking the "Trophies" option.

Press while you are injured and if you have a medkit available to heal yourself. Do this 10 times.

The theme of this game is to dismember Necromorph's Limbs in order to score a kill. Most of the time you're going to have to target the arms for a confirmed kill. You can also stomp () on dead corpses of enemies to dismember them and it'll count towards this trophy. It is possible to obtain this in a single playthrough, but don't worry about it considering that you have to do two anyway. A Zealot playthrough from the start will net you around 1500-1800 dismemberments. You should get this automatically while going for your Hardcore playthrough.

You will find the Schematic for the Advanced Suit in Chapter 11. Purchase it for 40,000 credits (36,000 if you have Vintage Suit equipped) to unlock this. See The Engineer trophy for location of the schematic. If you missed the schematic, it will be automatically added to the store during Chapter 13 just like the rest of other schematics that you may have missed.

The RIG and Stasis requires 18 and 12 Power Nodes respectively to fully upgrade them. You'll most likely achieve them very late in the game. On my Zealot playthrough, I focused only HP upgrades from the start for the RIG and did not upgrade the Statis Module at all until the later chapters.

You can exploit a glitch found by jpric18 of X360A which allows you to pickup unlimited Power Node to save yourself from an extra playthrough just for this trophy, see HERE.

See Fully Loaded.

To unlock the trophy, you simply need to have upgraded all stats of 4 weapons. You DON'T need to fill in every slot, just make sure that the slots that have effects are filled. I highly recommend you upgrade the Plasma Cutter and Contact Beam first, as they are absolutely crucial for Zealot and Hardcore difficulties.

You can exploit a glitch found by jpric18 of X360A which allows you to pickup unlimited Power Node to save yourself from an extra playthrough just for this trophy, see HERE.

You need to get a kill with each of the following weapons. Normally you will need to find the schematics for these weapons and bring them to a Store to be able to purchase them. If you missed a schematic however, fret not, the weapon will be added automatically to the store in Chapter 13, but try not to let this happen as some weapons are just too valuable to miss.

Plasma Cutter
Line Gun
Javelin Gun
Pulse Rifle
Ripper
Detonator
Force Gun
Flame Thrower
Contact Beam
Seeker Rifle

Missable. In Chapter 3, this rotating statue is infront of the Bold Stylings shop, the area where Daina labels Patient 5 a “Psychopath” and there’s music playing in the background. Shoot its limbs to dismember it, just like Venus de Milo. You revisit the place in Chapter 6, so you get another chance if you missed it earlier. Video by PowerPyx.

Missable. In the Main Frame room of Chapter 7, you’ll have to connect fuses in two circuit rooms with Kinesis. In the left circuit room (the one with the Slasher, not the parasites), as soon as you climb out there’s a holo-panel on your right with blue block symbol. Fit the circuits according to this holo-panel so they turn blue. This reveals a switch to rotate the cylinder to the secret room with Peng, power nodes, and a large medkit. The trophy unlocks immediately upon collecting the treasure and thereafter it can be sold for alot of credits. Video by Powerpyx.

Logs are acquired automatically throughout many dialogue transmissions between you and other plot characters, as well as picking up Audio and Text Logs that add more to the backstory of the game. I achieved this in Chapter 11 after passing through space. See the Collectible Guide for help.

Semiconductors are usually found after defeating tough foes such Tripods, Brutes, Bosses, and in Power Node-locked rooms. There are a whole lot more than 10 in the game and its very hard to miss this trophy. They can be sold for valuable credits.

Collect 10 Schematics that are littered throughout the game and bring them to the Store. The trophy will unlock after you bring the last one to the Store. Schematics allow you to purchase new types of weapons, armor, med kits and ammunition. See the following video by Powerpyx, or the Collectible Guide for help with this trophy.

This is easily done whenever you’re faced with The Pack (necromoprhs that look like kids) as they come in huge numbers, wait for 6 of them to come very closely and Stasis them, then fire the Line Gun’s Alt-Fire which is a bomb that will detonate in 3-4 seconds, killing anything nearby and hope you take 6 of them out. You can do this in Chapter 3 and Chapter 5 when you come across The Pack.

Just like My Boom Stick trophy above, but first use the Javelin Gun’s Primary Gun and fire at an enemy in a group, then Alt-Fire to activate an electricity field from that Javelin to shock nearby enemies.

I recommend using the Ripper's primary attack , which will extend a saw blade that hovers infront of you, on a group of weak enemies (preferably the The Pack) and quickly saw off their limbs with 1 Ripper Blade to unlock this.

Once you have acquired the Detonator Mine schematic and bought the weapon, press to deploy proxmity mines that will extend sensing lines. Any objects that interferes with these sensing lines will cause the mine to explode, dealing damage to anyone near the mine itself, and less damage to those further away from the mine or on the sensing line. This is a very useful weapon and I tend to shoot them on the ground so that they sense upwards and therefore the object/enemy has to be directly above to trigger it, thus receiving maximum damage.

Once you have acquired the Flamethrower schematic in Chapter 6 and bought the weapon, use this to burn 50 enemies. You should target weaker enemies like The Pack as the flamethrower tends to eat alot of ammo very quickly.

You will first encounter Stalkers in Chapter 4, but only obtain the Seeker Rifle in Chapter 6 and your earliest chance to use it against the Stalkers is in Chapter 9. They look like giant Ostriches and will run from cover to cover but peak with their heads out, then charge at you directly with their heads. You best chance to obtain this is in Chapter 9 in a large storage area and there are Stasis cylinders lying around in the ground. What you should do is Kinesis-grab one of the cylinders, wait for the Stalker to charge you and you fire the cylinder at it slowing it down. Quickly whip out the Seeker Rifle, hold to aim and to zoom, then dismember and kill the Stalker, earning you this trophy.

Pressing + with the Contact Beam equipped will make Isaac drive the gun onto the floor and create a sort of shockwave that will knock enemies in proximity down. Thereafter, quickly press and hold + to charge a ball of energy and decimate the enemy with your Primary Fire. Try to do this before fully upgrading your Contact Beam as it may be too powerful and kills enemies instantly when fully upgraded.

To impale an enemy, you need to either use Kinesis ( + ) and pick up a pole-like item or the Javelin Gun and fire it at a necromorph to impale them on the opposite wall. The target must stick onto the wall for the kill to count. Use stasis to buy yourself time to aim if necessary. If you use a Slasher's own arm to impale itself, you'll unlock Taste of your own Medicine at the same time.

Video by PowerPyx with the Javelin Gun.

Anytime you see a necromorph will those 2 extra arm-blades, shoot one of the limbs off, grab that broken arm with Kinesis and fire it back at them with them between you and the opposite wall and you should be able to impale them very easily. They have to stick to the wall surface.

This is basically the same as Vacuum Cleaner trophy above, only you're supposed to impale the enemy on a Decompression Window and he gets sucked into space immediately. One of the best places to do this is in Chapter 3, as you enter the Unitology Recruitment Center. A group of necromorphs will spawn infront of you and all you need to do is pickup a pole on the ground and impale any on of them on the wall at the far side. Remember to shoot the triangle icon to shut the hatch and save yourself from the same fate.

Hardcore is basically Normal difficulty, with a twist - you can only save 3 times, no more than that. The game will warn you and indicate how many save opportunities you have left whenever you approach a save point. Ammo drop rate varies between Normal and Survival difficulty. The game is fairly generous with Medpack drops, especially towards the end of the game.

Completing the game on Hardcore does NOT unlock Zealot difficulty trophy (i.e doesn't stack) and vice versa.

This setting is not for those with faint of heart and lacking dedication. Enemies are moderately tough and ammo is a somewhat limited resource. In addition you will need to be able to play for long hours as the game has 15 Chapters. You-will-be-dying-and-restarting, alot. Your first ideal save point should be somewhere in Chapter 6 or 7. Your second save point should be somewhere in Chapter 9 or 11. And your last save point at the end of Chapter 13 or end of Chapter 14 if you can make it that far.

Do refer to the Hardcore Difficulty Guide for useful tips and strategies. If you feel that this difficulty is too much for you to handle, consider investing in the Supernova Weapons & Armor DLC pack as the free items can turn this mode on its head as long as you make full use of your experience gained from previous playthroughs.

You’ll first encounter Lurkers in Chapter 5. These small little things will spring up their 3 tentacles when their about to shoot projectiles at your from a distance. Wait till their on the ground and when they do so immediately aim and fire your Line Gun with so that you cut off all 3 in 1 shot.

Video by Powerpyx.

You will have your first real fight with a Brute in Chapter 6 when you meetup with Ellie and Thross. He walks around with his two huge hands like a Gorilla (not to be confused with a Tripod!), has a running charge attack and his weakspots are the 2 areas between his left and right shoulders and body. Focus on 1 area only, wait for him to charge, run sideways then turn around and Stasis him and use the Plasma Cutter, Line Gun, or better yet a charged Primary attack from the Contact Beam. Once you break one of his limbs the fight becomes much easier as you can then stand from afar, wait for him to spit one of the mines and use Kinesis to grab it and throw it back, otherwise finish him with your gun. Be careful not to any damage during the fight, restart from last checkpoint if you do.

If you missed this opportunity, there are 2 more encounters in Chapter 10, one after the other, and a final encounter in Chapter 13.

Video by PowerPyx in Chapter 6 using Stasis.

See Epic Dismemberment.

A Cyst is a small round thing mounted on any wall/floor/ceiling and will shoot mines directly forwards if something approaches it. Grab something with Kinesis, throw it near the Cyst and it will pop the mine, grab the mine while its still in the air and fire it back at the Cyst for this trophy.

Near the end of the game, you finally catch up with Lexine boarding a Transport and two Infectors on the ground in front of you. Take the two Infectors out, and go around collecting all the items in the area first. There should be a Store and a Workbench in the previous area where you came from incase you need it.

When you're ready, hack the panel near the ship and a QTE event will occur. Complete the QTE and Gabe will be heavily wounded and lying on the ground. During this part, you are required to destroy 4 Fuses on the far wall in front of you while Necromorphs spawn from your left and right.

Delay destroying the Fuses and take out the Necromorphs instead. There's no limit to them so all you have to do is get your aim right until the trophy unlocks, then you can proceed with the final objective.

Missable.

After the Grinding House in Chapter 1, you'll come upon a barely living human calling out to you from above. Go up to him (he'll die in the process) and you'll see an Infector over his dead body. Quickly kill it (and the corpse if it gets up), then activate the panel in the middle. You MUST stay on this platform at all times. Credits Devilish47 for this info.

You will be ambushed by a couple of Leapers, Super-Fast Slashers and The Pack which comes in 3 waves, while the AI system counts down until the door nearby unlocks. Survive this section and the trophy unlocks.
