Playing Unreal Tournament 2004 I had one of these. There's an Assault mission which requires you to fight your way into a factory and destroy this giant generator. I was on the attacking team, and we hadn't been doing too well--we were down to the last 30 seconds, but managed to fight our way into the final room. After blasting at the generator for a while I was taken out by an enemy, respawned, grabbed a rocket launcher, ran out in to the central room with two seconds remaining, and, seeing the generator down to about 2% of its total health, fired the rocket, only to have the time run out before the rocket hit the core. On the freeze-frame screen announcing we'd lost, you could see the rocket about a foot away from colliding with the generator. Ergh.
