A few days ago I watched a Yogscast video on a Garry's Mod game that had an elevator going up, opening at funny floors and finally reaching the top to win.
This gave me the idea to suggest a game mode very similar to this, basically have a lobby/spawn area with several elevators, once those elevators reach a certain player count, they go up. Each floor the players will encounter a dangerous thingy (ex: mob, rockets, ect). The last player standing will win, gaining points.
