Well, you do get a flashlight. The darkness is really just so they can "hide" more enemies (hiding spots have been pretty obvious). But so far it's not impressing me too much. It's just been really repetitive... go into the next room, clear it out, be sure to check behind you, pick up more amor/health/ammo, rinse, repeat. I mean, it's not a bad game... just a bit overhyped IMHO.
