If the Ymir launches from the bay, and you’re still alive, then you win. Don’t let too many aliens attack the Ymir. It can be damaged beyond repair if it’s hit too much. Most enemies come from in front of you. Collier will always die, so don’t try to save him. (Designated red shirt.) You can only lose four maglocks. If shadow tanks get by you, they will pick off your buddies from behind. Watch all corners as Radar is useless until you reach the Ymir.
