DOOM 3 - Delta Lab Video #2 [Low]
As always, the shotgun is your friend and will be quite helpful if you happen to turn a corner into a foe. Keep it handy!
What the Delta Lab lacks in nifty, new-age, features like switches, it makes for by being built with classic FPS deathmatch in mind. While playing, be sure to grab the mega health that spawns over the red spot on the floor in one of the rooms.
