It doesn't get much darker than a post-apocalyptic survival romp through Moscow's ruined subway system, as proven by these very dark screens for THQ's upcoming shooter Metro 2033.
I've the type of person that gets really into my story-driven first-person shooters, to the point where I get extremely jumpy and, at times, have to turn off the game and sit in a well-lighted room to assure myself that there aren't radiation mutants lurking around the next corner. Metro 2033 looks like the sort of game that thrives on the darkness, which means I will likely play with the brightness setting on my monitor cranked all the way up. It isn't cheating if I convince myself my monitor is broken.
