Inside the VAULT there is also a small opening in the floor. Below is a roughly H-shaped network of underwater passages. Jump in...

...and swim to the left. When you reach the middle of the passage (just before the first floating corpse), turn right.

Swim through the diamond-shaped opening, then turn right again.

At the end of this passage, just beyond next two floating bodies, turn left...

...to find the final save/power-up crystal. Snag it, turn around...

...and swim back to the right.

Then follow the long, straight passage to the end, where you can surface. Climb out on either side of the pool, rather than in the middle, where there's a flaming barrel.

Shoot the armed guard and his dog.

Finally, climb the grating, through the trapdoor you opened earlier.

Then and approach the room full of goodies to end the level and the game.
