  • 1 of 3: When you reach an underwater hallway where you can surface for air, look for a nearby grate in the floor.
  • 2 of 3: Bash it and go through it and make your way to a big wrecky room. Surface for air again, then dive down and find all the Mp5 grenades and crossbow dart clips that are on the floor.
  • 3 of 3: To leave and proceed on your way, push against the computer that's in front of the door to get it out of the way.
