I'm gonna have to nominate Crackerz Cyanide Campaign, for that! Especially the second level, with the repeated assasination attempts! I'd have nominated Blood of Heroes, but

Crackerz based the plot on a movie, and

since I'm unable to play multiplayer missions, I haven't been able to try it (btw, any chance of a single player version?) It sounds really great, though. Oh, well.
So Cyanide Campaign, it is!
