Getting the Yellow Key / Getting to the Yellow Key Slot (2)

Before entering the movie set area, collect Shotgun Shells from the median, a Large Medikit, and a Shotgun. Getting the Shotgun opens a wall revealing two Pig Cops and two Enforcers, ideal targets for Pipebombs. Enter this revealed room to find a Portable Medikit.

Proceed down the hallway, eliminating two Pig Cops and an Enforcer. Collect the Blue Key from under a phone and a Pistol from a corner. A hint for Secret 1 is on the wall in the dark.

SECRET 1: Return to the room with two registers (where the Portable Medikit was). Interact with the right register, then run to the Blue Key room to find three Atomic Health items.

Exit to the front of the studio and go around the corner to the Crash Site. Engage four Sentry Drones and a Commander (if previously encountered). Collect Pipebombs and Devastator Ammo from the corners.

Enter the crash site itself to find two Freezer Ammo, Steroids, and a Large Medikit. Ascend to a ledge containing a Small Medikit.

SECRET 2: Reach the ledge with the movie poster and walk through the far right portion of it. You will find an Atomic Health, a Freezer on a higher shelf, and Devastator Ammo on the ground. Exit this area.

Use the Blue Key to enter Stage 17-A. Defeat two Enforcers, two Mounted Guns, and a Pig Cop. As you advance, a large door opens, unleashing several Troopers; use the Chaingun Cannon to eliminate them.

Search the boxes for Shotgun Shells, a Small Medikit, and an Atomic Health. To reach the Atomic Health, you may need to use intact props on the ground for jumping or utilize the grates. Two Devastator Ammo are on the floor, and RPG Ammo can be obtained by looking through the grates.

SECRET 3: Examine the boxes in Stage 17-A. The secret is located under the largest stack. You will hear a door open as you search. Jump onto crates or use the Jetpack (recommended) to reach the secret room, where a Sentry Drone guards a Devastator.

Proceed to the Moon Set. Deal with two Enforcers and two Pig Cops at the entrance, and another Pig Cop further in. Collect Pipebombs from a corner and Pistol Ammo from outside the set. A Portable Medikit is to the left of the entrance, and Chaingun Cannon Ammo is outside the set.

On the actual set, fight three Enforcers. In the middle of the set, amidst a pile of guts, you will find the Yellow Key, a Chaingun Cannon, and a Jetpack. Jump onto the surrounding ledge for an Atomic Health at the top.

SECRET LEVEL: Locate the USA banner on the spaceship. Searching it opens a door within the ship, granting access to the Secret Level Tier Drops.
