Rabbit Hunt
I saw this one once, players join as blue, while the host is red. They have to roast him a chosen amount of times, but he has a bigger opportunity in moving around the level. This mode is CTF-based.

Bird Hunt
After seeing Rabbit Hunt, I came up with this one. Instead of a rabbit, the server is a bird (use XJJ2 or JazzForce).

King Of The Hill
This was a single pack of about 3 levels. I forgot who made this. This is a kind of a race, where you go to a chosen point and then try to stay there as long as possible and as the only one there.
