Quick suggestion - infected

this is my first post, so i hope it goes well :O

How about a infected mode? 3 players are infected and have to hunt down the others? At the start they would be in a cage and have to break out, so the players can get a small run away. Heh...

Or maybe a mode where 1 player is in a cage, he has 1000 health and causes high damage. However, his life keeps going down 3 health per second, when he kills someone he gains a extra 100 health. (And the cage he is in takes 15 seconds to open. He can only use the weapons he purchased. (The infected one kinda looks like a zombie thing)
