Getting to the Red Key Slot (8)

Return to the moon set and approach the Red Key door.

Open the Red Key door and enter the room.

Inside, you will find two Laser Tripbombs (explosive devices that detonate when a laser beam is broken) and a Night Vision Goggles (item that enhances vision in dark areas) on top of a switch box.

Behind the monitor, there is a door. Open it to find two RPG Ammo (ammunition for the Rocket Propelled Grenade launcher).

Hit the switch located in this room. This action will open a wall back in the Entrance portion of the level.

Go back to the Entrance portion of the level.

Warning: A Battlelord (a powerful enemy) has spawned in this area at some point; do not engage it.

Proceed down the stairs.

At the bottom of the stairs, collect the Portable Medikit (a healing item) and the Chaingun Cannon (a rapid-fire weapon).

The Exit Symbol (indicating the level's end) is located here.
