GoldenEye 007 on Nintendo 64 - Agent Mission 7: Cuba - part iii: Water Caverns

1. Minimise scientist casualties

The goal of the level is to pursue Trevelyan. In practice, you can arrive before him, that works too :D. It's even easier because the doors are open. Normally, you can overtake him fairly easily on the big climb because by strafing sideways while moving forward, you go much faster than him. If you overtake him, don't go down the stairs after the crates room and take the first door on the right, then the big door on the left, then right. In the corridor there's an automatic pistol. At the end there's the elevator.

a. Minimise scientist casualties

If 3 scientists die, you lose. As an agent, if you head straight for the objective, you shouldn't even run into any.
