Lasting Light (Doom Mod)

The concept is simple, thrust into a sudden black-out and the ever approaching presence of the Screecher, Creeper and Stalker; you must take your lantern and make your way to the exit, before your soul falls victim to the dreaded monsters. You are utterly defenseless, relying only on the light of your lantern to keep you safe. Keep your fuel in check and your breath calm, those are the only things to keep you alive.

Note: I did not make the mod. Credits to Ral22 for the original mod.
