Head forward through the corridor and through the door. There's a store here, so be sure to stock up. Run through the next door and head through the corridor until you get to a large area you can utilize zero-G in. Jump all the way to the bottom where there's a blinking red outline. Run forward and make a jump so that you advance to the top of the structure. You'll float for a while, so just watch Vandal rise and rise. When you reach the top, you'll be greeted with the enormous boss monster you need to eliminate to complete the game. Aim for the yellow areas on its tendrils and keep pumping away at it with the Corer .As the fight progresses, more Necromorphs will pop up from the sides to attack. Take them out, then focus on the boss. Its tendrils can grab you and knock you over, so be prep
