My vote is for the Zombie Bot, mostly because it revives its self over time after it dies.

Zombie Apocalypse has been disqualified. "Bob's Vortex Bomb" is copied entirely from previous code. All votes for it equate to naught.
I would remove it from the poll, but that resets the votes.

/facepalm
Oh person who made Zombie Apocalypse.... We expect so much better from you...

Oh ok, I thought since he was out, we could use his name.

My vote would go to DBZ, Plasma Zombie or Zombiebot(They live!).

-Definitely Better Zombies: I consider this only because of the wraith. It's not done before, and it's loads of fun. The wraith really gives you a paranormal feel, and it's just cool even looking at it. However, I find the other actors redundant, they're just 'another zombie'.

-Plasma Zombie: It's terrifying, it's cool. And the visuals are even more paranormal than the above one.

-Zombiebot: Be sure not to over-look this one. When those pieces of scrap starts reforming into a new zombie, you'd be horrified and amazed. It is also one of the few actors than runs very well, and has well-setted jumping. A real feeling of a predator when you use it.

EDIT: I like these 3 because they give you the feeling of a title monster of a horror film. And you can be playing those monsters, killing victims one by one in campaigns. Or in zombiebot's case, fighting it as well.

The others feel like just 'zombies' or 'zombies with armor'. They're not cool enough to be used as an army of choice, nor do they include missions or activities that allow you to fight them. As finished pieces of contest entries, they are somewhat lacking.

Speaking of the Wraith, I have improvements on the possession code. I am reqesting permission to upload.

EDIT:
Just PM to Duh, whoever made it.

The Wraith might be better for sinking through the earth and flying around
and all that if it had a real jetpack, so it wouldn't fall unhindered through the bottom.

Also, I discovered in the Plasma Zombie that the radius at which the particles are go
smaller when when you crouch, and bigger when you attack. I also discovered that it
could die if you shoot it enough. Also, it can't go through loops...?

I couldn't wrap around all of grasslands with the plasma zombie.
But it still gets my vote.

Im voing for the zombot, its the only thing that really appeals to me in this one, because it doesnt really look like a zombie, and the plazma thing is a bit too over powered, and the rest are just zombies :/

Wraith isn't a zombie.
The plasma zombie is more like a plasma ghost, and it's pretty easy to kill if you have some grenades and a machine gun.

Its critical weakest is tight spaces, cripples its movement a lot.

May the tight corridors protect you, and be with you always.

Except that it can just concentrate its plasmay-ness all together with crouch and melt through the tight corridors.

I still cant believe how dissapointing this was. i thought i was the only one who left this too late cause of study, but apparently not. oh well. i'll develop my entry more afterwards. it was good and inspiring, but schools been a pain at the moment.
oh well.

As has been stated, the "Plasma Zombie" should really just be plasma ghos- wait a second, maybe its ectoplasm! See, ties into the undead spooky theme too. The wraith is fun, except it should have a jetpack, just for ease of movement. I love the (they live!) thing's sometimes regenerating ability. The first time I used it I shot it, it died, and I turned away. Then after a few seconds I just looked and went "whaaaa...?"
And the Count could've been better, but wasn't bad.

Most of these are a bit meh, but I like the Plasma Zombie gameplaywise (although it seems to be unable to move freely on rotating maps, I think you know what I mean).

IMO the Zomborg robot thing is the best one, since I just love lunging at my opponents with a pair of huge claws, and the two other guns are kind of ok, gets my vote anyways (it's funny as I've been thinking about making the exact same actor for quite a while now)

The zombiebot is pretty balanced. If you kill it, aim for the head! If you destroy the head, he won't resurrect.

Just found that out when I bombed it with a cruise missile full of C4.
