Head through the corridor and through the door. There was a Store here so be sure to stock up. Run through the next door and head through the corridor until you got to a large area that you could utilize Zero-G in. Jump all the way to the bottom where there was a blinking red outline. Run forward and make a jump so you could advance to the top of the structure. You would float for a while so just watch Vandal rise and rise. When you reached the top, you would be greeted with the enormous Boss that you need to eliminate to complete the game. Aim for the yellow areas on it's tendrils and keep pumping away at it with the Corer. As the fight progressed, more Necromorphs would pop up from the sides to attack. Take them out and focus on the Boss. It's tendrils could grab you and knock you over so be prepared to jump back up to your feet. Keep taking the yellow areas out on it's body one by one. Avoid it's sweeping tendril attacks. The yellow spots would reappear as you eliminated them over and over. When you damaged it enough, it's tendrils with yellow spots would be hanging over the balcony. Destroy them and a yellow weak spot on the monster's back would appear. You need to use the giant drill in the middle of the room to pummel the creature and shoot the yellow weak spot on it's head to terminate it. You would be grabbed by a tendril as Vandal's helmet flew off, setting the stage for the end of the game to ensue. Watch as Karrie Norton was revealed and hang in there for the rest of the game. Congratulations! You just beated Dead Space (iOS).
