I made my own mode called "Float!"
Basically, it will be a FFA King of the Hill. However instead of normal KOTH, you aren't allowed to touch the ground or roof.
With a Concussion Rifle and Golf Club your goal is to float around the arena killing everyone else and be the last one standing. It's best of 3, 5 minute rounds. When you die you go into a spectator area where you wait until the next round.
Sound any good to you folks? Imagine this with 12 players all going at it.
