Find a way through the Derelict to find the prisoner | Mission 8: Rampart A: CM Guide
Last update: 11 May 2016
Move through the linear corridors and after a while you'll find yourself in a larger room (the above screenshot) in which you'll run into some new enemies. Notice that the game gives you a chance to surprise them; it definitely pays off to use this opportunity and deal with several closest enemies before they have a chance to return fire.
In subsequent battles, try to get rid of enemies from a large distance and find covers as you go so as not to become an easy target for anyone. Don't use grenades this time; since the fighting takes place on small galleries, most of them may land in the wrong places.
Keep moving forward, picking up whatever supplies you find. Make sure to look inside the first building you'll pass by (the one on the right); there is an Audio Log inside. When you take it, head for the second building (left) and go all the way through it.
Get ready to eliminate the last group of mercenaries which will show up by the door at the end of the current area. Traditionally, take proper precautions when you notice the heavily armored enemy. When the battle is over, search the place for collectibles (the elite soldier should have a full set of armor) and use the elevator pictured on the screen.
Wait until the elevator takes you to another level and move forward. Don't hurry; as soon as you reach the above area you'll be forced to fight off fresh waves of Weyland-Yutani mercenaries. Luckily, the underground complex facilitates the use of grenades, so use them a lot to kill the enemies hiding behind covers.
Continue onwards until you reach the large oval room. Make your way towards the platforms on the left, but turn right the first chance you get. Examine the end of the above gallery to find a new Dog Tag (Cpl S. Baroski).
Afterwards, retreat immediately and hide behind a cover, because new enemies will start showing up in the distance. If possible, try to shoot them from as large a distance as you can, using the scope. Same as with the other battles, be on your guard when it comes to the heavily armored soldier.
When the fighting is over, pick up supplies and make your way towards the only exit here (the above screenshot). Follow the linear corridors. There'll be some more fighting on the way, but, providing you don't charge, use grenades and your best weapons, not too challenging. Continue the way towards the exit and you'll get new objectives.
