revised zombie mode

now this might be a wild idea, i'm certain just about everyone who's played CF as long as i have, have at least seen pictures of zombie mode

now i'm a wee bit curious about this because it seems like the gameplay will become extremely monotonous with the humans sitting in a corner while the "zombies" charge them
this gameplay seems like it'll be fun for an hour but then will just become quite boring
i think it'd be neat to have at least lower powered zombies controlled by the player that are faster and aren't knocked back

or better yet (this has been suggested several times for awhile)
a co-op mode where you play NPC zombies
but wait why stop there why not make NPCs with guns, where you play co-op missions with 1,3,7, or 15 other players, with the gp reward being from 100gp to 5000gp depending on difficulty and time consumption
