In this level you have to explore the temple and the labyrinth underneath it to find a pda that will allow you to open up the portal to win the level. Enemies and weapons in the labyrinth are placed
randomly, so be sure to explore it thoroughly to find powerups and stuff. You have unlimited flares (press F to use them). You can return back to the surface at any time to heal yourself at the health machine and the first time you go back there will be ammo lying on some of the boxes. It was left there by the magical helpful gremlins who live in the temple and keep all the candles lit. There is no second level, so it will say map not found when you reach the end. Read the pda once you find it. It tells you where to go. No quicksaving until you get to the final room. Unless you are a lameass who is scared of the dark! You really might want to quicksave when you get to the final room. Go back for health and ammo.
