Dead Space: Extraction

This trophy is story related and cannot be missed.

This is the first real fight you'll face, and it's a tough one. It's the last thing you'll do at the end of Chapter 6. When you enter the large open space you'll find yourself being attacked by large tentacles. The two front tenticles will move into the air, they will now simultaneously open at the end to reveal their 'yellow eyes'. When one of them does this you need to fire at the yellow eye to damage the tenticle, It will then back away. If you don't do it correctly you'll get swiped, and there is no blocking it.

After you have damaged both tenticles a couple of times you will move onto a walkway to the left or right. On here will be a fan, as you take a quick glance at the fan you want to use stasis on it to slow it down, to use stasis simply press the (DS3) / (Move) button. Damage the tenticle that is facing you until you have the option to look around, turn to face the fan, if you managed to use stasis on it then you will head inside he vent. The tenticle will follow you inside here and try to hurt you, when its yellow eye opens again shoot it & the tenticle will get caught in the blade causing the tenticle to be cut off. You'll now move back out into the centre of the area again.

Continue the previous process of damaging the last front tenticle until you move onto the next walkway. Use the same idea again as before. Stasis the fan when you look at it, damage the tenticle, when you have the option look at the fan to climb inside, damage the tenticle eye so it gets cut off. After that you will move into the centre area for the last time.

The next part is fairly simple. His two rear tentacles will attempt to grab you and drag you towards his mouth where he'll start biting you. If this happens keep firing at his mouth to get him to release you. What you have to do is pick up the floating red canisters using stasis and then throw them at each tentacle as it starts to come forward to grab you. You only need to do this once on each tentacle.

Finally he'll attack you with a ranged goo that hurts you. Thankfully spamming your rock saw with (on a DS3) stops you from taking any damage from these, but with Move you'll need to use stasis. While doing this aim with any weapon you've got at the large yellow lump on the bosses body. After enough hits it will die. As soon as you kill it the Chapter will end.

If at any point you die you'll get taken to the start of the boss fight again with low health and no health containers inside the two vents making it a lot harder, so try to do it first time. I used the Line Gun for the whole of this fight as it acts like machine gun and fires off a load of bullets at one time, this helps to make sure you hit your target.
