E2M4: The Testing Labs (Full On)

E2M4: The Testing Labs is the fourth map of Full On. It was designed by Tim Ackroyd.

Secrets

 * 1) After getting the yellow key, jump down into the lava to the north to a platform with a megaarmor (there are two sets of pillars that can be used).  This opens up a door in the southern lava section leading to a BFG9000 and a teleporter.  It can be reached by heading directly south of the megaarmor platform where a lift will raise you back to the walkway.  Note that if you drop into the southern lava section before opening up the secret door, it will be impossible to get out. (sector 225)
 * 2) Towards the south of the level is a corridor that lowers when an armor bonus (on medium and hard skills) in its centre is collected.  After lowering the floor, a door will be visible to the north.  It opens on shooting, revealing a path leading to a medikit, a box of shotgun shells, a megaarmor, and a partial invisibility. (sector 130)
 * 3) En route to #2 you will pass two other doors which open on shooting.  One of them has a rocket launcher behind it. (sector 134)
 * 4) The other door has a box of rockets behind it. (sector 136)
