Right now, I'm compiling a list of cliches from first-person shooter games, and I need help. I've thought of a whole lot of them, but I'm running dry. Even playing the first Doom and TimeSplitters 3, two cliche-ridden games, for ideas didn't help. So post some (hopefully) well-written cliches here and I might be able to put them in the list.
I've already gotten the obvious ones (exploding barrels, overuse of plasma weapons, etc.), so try to be original. Also, try to give the cliches clever names if you can, so I don't have to do too much work.
