Posted it in my squad's private FB group, but everyone said "awesome" and haven't been giving much criticism and would like some.
NOTE: Just about all of these, besides perhaps the first one, will be played by a mod or admin (and even then the first one likely will also).
All of these are based in part of the 4 Horsemen of the Apocalypse and likely only one of each type.
Conquest: Has a sword (perhaps Nerf sword) and a 1-2 minute stun time. Wears a long red bandana above the orange. Pretty much a charge into the action zombie. Thinking about making any hit, even on the sword count as a stun. I know the Nerf weapons hurt, so it will likely be used by an admin/mod or a very padded weapon.
Starvation: Three darts or two socks to stun, doesn't actively attack humans but will grab darts and socks, even if it is one it is stunned or semi-stunned by before the sock or dart hits the ground. Darts/socks are returned at the end of the game or mission. Has a long, thin, black bandana above the orange. Thinking that the return rate may be reduced as time goes on. So it starts off as after the mission, then only 1/3, then 1/2, then only at the end of the game or after a person is killed. Not sure how it will play out, since a lot of people will leave ammo around, but it would serve as a game mechanic that cleans up after the humans.
Plague: Either gives out minor power ups/exp. to zombies or acts as an instant respawn. Chooses when to do it via a high five. Has a long green bandana under the orange. Not sure if this should be stunable, as the person will not be a constant respawn and will be a mod or admin. If it gives out power ups (perhaps spitter socks or shields) it will be able to be stunned and would have to be protected (thinking the power ups are a one time thing, once you are stunned, you lose the ability and have to return it, but the added stun timer is only for the Plague, which would have zombies protecting it a bit, which could be a problem).
The Reaper: Slow zombie, literally walking, so speed walking. Cannot be stunned though (slow but always coming for you, like death). Has a long off color or light grey bandana under the orange. Kind of like a tank I've seen at other schools. It is used only to keep the pressure on humans to keep moving, not specifically to turn them. Could make for a nice rock and a hard place scenario though.
So there you go, like it, hate it, love it, loathe it? Not really sure if it would or could play into the game as a theme, just as special typed zombies.
Oh, and if you simply like all of these, what would be your take on a Nemesis? Zombie with a blaster that takes multiple shots (10-20) as a final boss? Thinking about having an evil scientist turning into one, depending on how the game works out mission wise. I wouldn't have it able to kill all the humans, perhaps just 1/3 - 1/2 of them. This would be either an optional thing, face it or run, or would actually be the final thing to kill. Slow moving and slow fireing as the zombies either surround it or attack at the same time. Again, this would be a mod/admin, so it wouldn't be gunning humans in the back as they faced an entire horde, perhaps an in between rush type of thing.
