STORY RELATED CAN'T BE MISSED. Awarded after completing the game on the Hard difficulty setting. Stackable, however, when you first start playing the hardest difficulty available will only be Hard, so after your first runthrough you'll only be able to get this trophy and Survivor.

You'll unlock the Extraction Site Challenge after completing Chapter 2 of the story mode. The top score is 251,010 so you need more than this to earn the trophy.

You get 250 points for each limb you take off, 100 for each item you pick up and 20 for each perfect reload. You then also get points on a sliding scale based on how many enemies in a row you kill without taking damage, starting on 500. So if you kill 2 enemies without taking damage you get 500 for the first and 550 for the second. If you build this streak up to 20 you'd get 1,450 points for the 20th, 1,500 for the 21st and so on. I managed to get a 91 kill streak (there are only 91 enemies) and ended the challenge with 289,238 points. If you take damage in the first 6 waves restart or you won't have enough of a streak to get the required points.

I have found an incredibly easy way to get through some of these challenges. The flame-thrower. You can't unlock this until Chapter 3 in the main story and you'll not be able to fully upgrade it until the end of Chapter 8. Now if you are using a DS3 (recommended for challenges), what you need to do is constantly spam so you are using your rock saw. This acts as a sort of shield against necromorphs. While doing this you also want to gently tap while having the flame-thrower as your weapon (be sure to select it as the starting weapon before you begin each challenge). This will give off jets of fire which will set light to the necromorphs. You won't be able to get full points for dismembering limbs, you'll get a flat rate of 500 per kill + the sliding scale multiplier. This is more than enough to reach the score targets however.

The benefit of doing this is that you start with around 300 shots of flame which easily lasts until round 5-6. You also get 100 shots for every pick-up so be sure to check out crates and of course the floor after killing necromorphs. All you need to do is set fire to the necromorph and let them burn for easy points. When a necromorph is set alight it also staggers backwards a bit so you don't need to panic if they seem like they are about to hit you. It's an incredibly easy way to take out 3-4 at once when a normal gun would leave you getting swamped and more importantly, taking damage which kills the streak. Just remember, gentle bursts and not keeping your finger on the trigger or you'll be out of shots in no time. If you do find yourself out of shots then switch to one of the weapons you randomly got during the challenge and make full use of it until you get more ammo for the flame-thrower.

You'll unlock the Central Plaza Challenge after completing Chapter 3 of the story mode. The top score is 252,010 so you need more than this to earn the trophy.

Refer to the tactic in Overtime Sheet for this challenge. You'll face a new enemy, a flying necromorph. You need to be aware that they will swoop at you so be sure to be spamming so your rock saw stops them from damaging you. At the same time press to fire your flame-thrower and you'll set them alight so they burn as they fly around. I managed to get an 82 kill streak and ended the challenge with 277,631 on my first attempt so this is very easy. If you take damage in the first 6 waves restart or you won't have enough of a streak to get the required points.

You'll unlock the Maintenance Bay Challenge after completing Chapter 5 of the story mode. The top score is 253,010 so you need more than this to earn the trophy.

This challenge sees the introduction of the small necromorphs with the 3 tentacles sticking out the back. They will keep their distance and shoot at you. You'll also face the large mother necromorphs that spawn those annoying little things that damage you. For this reason the Flame-thrower tactic can't be used effectively. It is still possible, however you'll need to switch to the Rivet Gun to dispatch the necromorphs, or wait for them to move closer before you get them with the Flame-thrower. Provided you are using a DS3 and pressing , it is possible to deflect the projectiles they shoot at you, although if you're facing a number of them they'll get through. The best way I've found for this challenge is to use the Line Gun. Not only is it great for taking out the mother necromorph before it releases it's babies, but if you aim in the middle of a necromorph with the Line Gun you'll completely de-limb every part of his body which is 1,000 points right from the off. The only problem is you run out of ammo really fast so try to build up a streak of 50-60 at the start then switch to the Rivet Gun and whatever else you get. I got a streak of 49 and ended the challenge with 278,297 points. There are around 140 enemies so if you manage to get 3 streaks of around 40-45 or one streak of 80-90 you'll be fine.

You'll unlock the Mess Hall Challenge after completing Chapter 6 of the story mode. The top score is 254,010 so you need more than this to earn the trophy.

This is another really easy challenge and you can make full use of the tactic explained in Overtime Sheet. This challenge introduces necromorphs that fire goo at you. These can be destroyed with the DS3 rock saw attack. Alternatively you can catch the goo with kinesis and throw it back with . Be ready to use stasis on the mother necromorphs, and on the rare occasions when they are too far away for the Flame-thrower use your Rivet Gun. I got a kill streak of 118 (all of the enemies) which gave me 486,685 points. You want to aim for a streak of around 60-70 or 3 lots of 40ish to hit the target. If you get hit before wave 6 restart.

You'll unlock the Medical Bay Challenge after completing Chapter 6 of the story mode. The top score is 255,010 so you need more than this to earn the trophy.

This is another really easy challenge and you can make full use of the tactic explained in Overtime Sheet. I got a kill streak of 118 which gave me 536,550 points. You want to aim for a streak of around 70-80 or 3 lots of 45 to hit the target. If you get hit before wave 6 restart. Don't forget if you run low on ammo for the Flame-thrower to make use of other weapons. Early on you can use the Rivet Gun (if it's fully upgraded) and it does some serious damage, saving precious ammo for when you've facing multiple necromorphs. As usual make sure to use stasis on the mothers before they unleash the little necromorphs. If she does get the Flame-thrower out and fry the floor infront of you to stop them jumping on you.

You'll unlock the Water Tunnels Challenge after completing Chapter 8 of the story mode. The top score is 256,010 so you need more than this to earn the trophy.

This is another easy challenge and you can make full use of the tactic explained in Overtime Sheet. I got a streak of 63 which gave me 294,514 points. As with the other levels, a streak of 80-90 or 3 streaks in the high 40's will be enough to reach the required score. This level is the first time you'll meet those annoying necromorphs with the really long and thing neck and a head. They are very fast and are what constantly destroyed my streak so always be ready to fry them as soon as they appear, they take priority. You can always use stasis on them to slow them down but in my experience once they are being burnt, they won't then hit you.

You'll unlock the East Grow Chamber Challenge after completing Chapter 8 of the story mode. The top score is 257,010 so you need more than this to earn the trophy.

As we get further into the levels, making a streak of almost all the enemies becomes less important. 6 levels in, and the top score requirement has gone up by just 6,000. In contrast, the number of necromorphs in the first level was less than 100 yet this level has almost 160. This means a lot more points so getting hit once doesn't mean you need to instantly restart. I got a streak of 71 which gave me 384,083 points. A few streaks of 40's will do the job too though. While the tactic in Overtime Sheet will work fine, for this level I decided to use the Force Gun. There is a simple reason for this, this level contains a lot of containers making ammo less of an issue. I also find that the Flame-thrower can be a bit slow when trying to take out the dark necromorphs, while the Force Gun will happily take out 2 or 3 of those guys in just 3 shots. On top of this every limb is blown off the necromorph meaning you maximise your points. This counterbalances the higher likelyhood of actually taking damage and ruining your streak.

You'll unlock the Shuttle Bay 47 Challenge after completing Chapter 9 of the story mode. The top score is 258,010 so you need more than this to earn the trophy.

Yet another level where the tactic explained in Overtime Sheet works wonders. Alternatively the method explained in Herbal Remedies also works well as there are just under 200 necromorphs to this level, a staggering 40 more than the last level, and again the top score only increased by 1000 points. This is an extremely easy level to beat. I got a streak of 80 which gave me 455,050 points.

You'll unlock the Atrium Challenge after completing Chapter 9 of the story mode. The top score is 259,010 so you need more than this to earn the trophy.

This is another straightforward challenge that can be done using either the tactic outlined in Overtime Sheet or the one in Herbal Remedies. There are not any new enemies, although the map is quite a large one so you might find it a bit harder using the Flame-thrower. I got a streak of 56 which gave me 408,586 points. As there are a whopping 220 enemies in this challenge, getting a high streak is really not important.

You'll unlock the Life Support Room Challenge after completing Chapter 10 of the story mode. The top score is 260,010 so you need more than this to earn the trophy.

This level is a strange one because it is done in zero gravity. Because of this, the type of enemies you'll be facing are just two, the ones that crawl along the floor and attack you with their tail and the little baby ones with tentacles that fire at you. What this means is that you'll be able to use the tactic from Overtime Sheet, but you'll also need to be ready with the Rivet Gun as the baby necromorphs never get close enough to be able to get shot at with the Flame-Thrower. One thing to note is that at the end of each round you'll have to jump to the next ledge before the next round starts, which means you'll be able to reload all your weapons and pick up all the ammo before you do this. I got a streak of 52 and that gave me 280,591 points. There are not so many enemies in this round so you'll want to aim for as big a streak as you can. 80+ is good.

This can be a very tricky trophy to get as it requires a bit of skill and a lot of luck to get your timings correct. It can be obtained at the beginning of chapter 4.

Your aim for this trophy is to survive this flight but in the mean time take enough damage to get your ships defences down to less than 10%.

You will start off this mission by manning a cannon, your task is to fend off any asteroids that are about to hit you. Aim for the red asteroids as they are the only ones heading towards the ship. Here you will actually want the majority of the asteroids to hit you causing your ship damage to go down slightly everytime. During this section I only shot about 10-15 of the asteroids, the rest I let damage the ship.

Once the battle with the asteroids is over you will be facing another onslaught but this time from friendly fire. Look out for the white balls in the sky that are flying at you here. Once again you need to make sure you defend yourself enough so you don’t die but take enough damage so you can earn the trophy. This is the last portion of this flight so you need to get below 10% before the firing stops. During this section I let about 50% of the shots hit the ship.

You can keep an eye on your ship's damage percentage by the small symbol in the bottom left hand side of the screen. When your screen goes slightly red, alerts start blaring & the symbol turns a red colour you will be at less than 10% so try and keep it there from then on.

As I said before it’s all about timing, if you happen to die or don’t get the required percentage by the time you reach the Ishimura then just restart the chapter as this section is at the very beginning.

NOTE: When I earned this trophy I was on Normal difficulty.

To achieve a perfect reload you need to press to reload your weapon, then watch the radial dial cross-hair on your screen and when the blue bar is inside the grey area hit again. You should generally get into the habit of doing perfect reloads as it greatly speeds up reload time. I've found the rivet gun to have the easiest perfect reload bar. You also have infinite ammo so you could theoretically "farm" this. When you get to a point in a chapter where you've got to open a door, don't. Instead shoot your rivet gun once then reload. Repeat until you're confident you're up to 80% or above. Best done in the earlier chapters such as 1 or 2.

This is pretty simple and refers to firing your weapons. Yes, all weapons count towards getting this. You can't fire one shot with the plasma cutter getting 100% and then use another weapon for the rest of the Chapter firing whenever you like. With whatever weapons you use you need to hit 80% all the time.

To make this trophy easier for you I would simply wait until a necromorph is right near you. This increases the target meaning you have more of a chance to land a shot.

Another trick you may want to use is with the rock saw weapon you get on Chapter 1. If using a DS3 you can constantly spam as a necromorph is near you; it basically creates a small barrier meaning you are less likey to get hit. Now as the necromorph is right in your face you can pick off your shots more easily.

Getting 80% Stasis accuracy is a walk in the park. On any Chapter use stasis on a necromorph one time. Make sure you do hit it. Now simply don't use stasis again for the rest of the Chapter and you'll get 100% accuracy. This is best done in the earlier Chapters, as later on you'll find you actually want to make use of it. Try to do this in chapter 1, 2 or 3. To use stasis simply aim at whatever you want to hit and press (DS3) / (Move) to activate it.

Earned while going for Mega Star. See that trophy for help.

Earned while going for Mega Star. This trophy should be earned during your first story mode playthrough.

Earned while going for Mega Star. Unless you're really struggling with the game, 3 stars should easily be achievable on each Chapter the first time you do it. Therefore you'll most likely earn this trophy during your first playthrough of the story.

• The amount of damage you take
• The number of times you restart because you failed something or died
• Your accuracy with a weapon
• Your accuracy with stasis
• The number of items you pick up
• Your puzzle success rate

Oddly, difficulty does not play a part in determining your rating. For this reason I highly recommend you attempt your 5 star run on Easy. That way if you do take damage it will be very minimal. Even if you never use stasis in normal play, make sure to use it at least one time and hit a necromorph so that you end with 100% accuracy. If you don't use it at all you'll get 0%.
