Getting to the Red Key Door

In The Cinema, press the switch near the glass to open the curtains. Break the glass and shoot an RPG round at the crack in the screen.

From the upper area, shoot at the four Troopers below. Jump onto the seats to avoid falling damage and eliminate the remaining Troopers.

Warning: If you walk on the seats, another Trooper will spawn.

Collect Pistol Ammo found between the rows of seats, near the doors, and on the movie stage. Body Armor is also on the movie stage.

SECRET 7: Jump into the hole in the screen. Kill the two Troopers and take the box of Shotgun Shells and the Jetpack. Break the window.

Outside, throw a pipe bomb to kill the Pig Cops.

In The Street, use the Jetpack to get onto the bridge above. Kill the Pig Cop guarding the exit.

SECRET 8: Drop onto the ledge below the bridge. Follow it around to the front of the street, picking up a Large Medikit on the way. Continue until you reach the cinema sign.

Jump onto the nearby palm tree, then face the windows and jump into them to reach a room containing a Chaingun Cannon, a Shotgun, an RPG, and some Pipebombs. Return to the bridge.

On the Bridge, use the Jetpack to ascend as high as possible.

Warning: You will take laser fire from Mounted Guns. Destroy these with the RPG and enter the small ledge.

Collect Shotgun Shells and a new Jetpack from the ledge.

In The Pig Room, open the door opposite the Exit Symbol. Kill the Pig Cop inside.

Toss a Pipebomb at the canisters in the middle of the room and detonate it to likely kill the remaining Pig Cops. Open the next door.

In the Box Room, kill the Pig Cop, take the box of Shotgun Shells, and head back to the Snack Stand Room through the theatre entrance doors.

Be aware of a Trooper at the theatre entrance doors.
