You can make one of the two doors on the train car before the fight with General RAMM stay open. Open either door and go to the other door. As the screen darkens, press X to open the door. Note: You must allow the screen to darken first before pressing X. The door will stay open during your fight with General RAAM. You can go back to collect ammo and/or weapons, but the Kryll that appear from the sky can get you while you are in this train car. When Dom says "Kryll", you will die if you stay in this train car.
