Getting the Yellow Key (2)

You start in a small transport vehicle. Inside, find Pistol Ammo and a Small Medikit. The next room contains another Small Medikit.

In the following room, a compartment on the left wall holds a Shotgun. The third room has three Sentry Drones; close the door quickly to try and make them explode.

In the 'View Room', an Enforcer, two Troopers, and a Sentry Drone will attack. Find Shotgun Shells, Chaingun Cannon Ammo, and two Large Medikits. In a compartment near the exit, find Night Vision Goggles. Activating the switch in the middle opens viewing windows and a door to the right, which contains a Sentry Drone and Atomic Health.

SECRET 1: Open the obvious door near the computers to find Pipebombs.

SECRET 2: In the back of Secret 1's compartment, a secret door leads to Body Armor.

In the 'Hallway', two Captains are present. Near the forcefield, find a Small Medikit.

SECRET 3: Jump through the 'Earth Defense Forces' logo on the wall to get a Portable Medikit.

In the 'Armory', go to the top of the ramp; the wall opens downwards. A Trooper attacks inside. Find three Laser Tripbombs within armory doors. Elsewhere in the room, find Shotgun Shells on a computer and Pistol Ammo near the exit.

SECRET 4: Facing the armory, go right to panels with green lights. Open the right panel to reveal a secret area, causing an Enforcer to drop. The secret room contains a Freezer and a Holoduke.

In the 'Rotating Platform Room', the floor raises, and three Troopers attack. A blue-lighted platform has two rotating platforms with Atomic Health. A Chaingun Cannon is located behind them. After collecting these, two more Troopers spawn. Be aware of a Mounted Gun in this room. Pressing the switch drops the forcefield in the hallway and releases Sentry Drones.

SECRET 5: Facing the rotating platform, look right. Open the right panel with green lights to find Chaingun Cannon Ammo.
