The catacombs of the Marathon, and a standoff - the Marine stares down a Compiler. This picture has always struck me as a little strange; the Marine's proportions look out of whack - his wide stance and long legs don't really match up with his shorter torso, and his helmet looks a lot like a welder's helmet. The compiler, on the other hand, looks singularly deadly. A larger version (549x691, 113k) shows the detail a bit more clearly.
