Getting to the Exit (19)

Board the conveyor belt in the Crane Room and wait to be picked up.

Upon landing, you will be attacked by a Trooper and a Captain behind some barrels. Steroids can be found there.

A Large Medikit is in the opposite corner, and Protective Boots are on the same wall.

Be extremely careful of the potent acid pit, which can damage you even without direct contact.

If you lack a Jetpack, save your game before attempting to cross the acid pit. Equip your Protective Boots, run up the acid fall, swim under the obstacle, and swim up to a platform with barrels.

A Trooper is behind the barrels on this platform. Microwave Expander Ammo and a Large Medikit are also present.

Exit the small door to face an Alien Drone and a Trooper.

Collect Chaingun Cannon Ammo and Shotgun Shells from the window sill.

Past the window, a switch unlocks an elevator leading to the beginning of the area.

Alternatively, a passage just before the window leads to another elevator that also descends to the same area.

Proceeding left then right from this area leads to a room with barrels and three Troopers.

You can enter the pool in this room to find two Devastator Ammo and an Atomic Health, guarded by Octabrains.

A switch near the pool allows access to the top of the barrel moving complex.

On top, find Pipebombs, two Chaingun Cannon Ammo, and a Large Medikit.

Drop down to the side opposite the door (into the water to avoid damage). Before dropping, consider using Pipebombs to clear the area below, which contains a Battlelord, two Octabrains, and Slimer Eggs. A Jetpack is very useful here.

After defeating the Battlelord, collect the Atomic Health near the pool and dive in.

Swim down the green column.

Take out the four Octabrains, possibly using Pipebombs.

Reach the very bottom of the green column to find the Exit Symbol.
