MAP07: Research Lab (Doom 64)

MAP07: Research Lab is the seventh level of Doom 64, designed by Tim Heydelaar. The level is where creatures are being kept for study, but most have escaped. The level introduces nukage for the first time along with the radiation shield which appears as a bio-hazard sign instead of an actual radiation suit. It uses the music track "Relentless Coil".

Secrets

 * 1) After seeing the blue key for the first time, continue onward until you see a door. Check the wall on the left before the door to reveal a secret room (sector 101), leading to the cages housing an imp with boxes of rockets, and a rocket launcher with a Hell knight in the next cage.
 * 2) Go back to the door at secret #1 and press onward until you reach a room full with broken monitors and a blue door to the right. Take the left path until you find a room at the very end where a super shotgun is on a platform and a small health pack in the corner. Pick it up and jump onto the ledge, and follow the ledge while hugging the wall. The end of the ledge (just behind the stimpack, with a green light) has a fake wall hiding a computer area map. (sector 291)
 * 3) After picking up the blue key, the wall behind it can be lowered to reveal a soulsphere inside. (sector 95)
 * 4) Once the blue key is obtained, return the blue door and continue on to the lift after dispatching the monsters. Instead of going up the lift once it's lowered, access the right side of the wall to reveal a hidden room containing several shells and small rocket pickups, along with a berserk pack. (sector 236)

Trivia
