Grave Matters mod for Half-Life 2

Grave Matters: The Invasion of the Moonboot Zombies From a Planet Just off the Coast of Finland is a comic zombie survival mod for Half Life 2 where you take the role of Bob, who missed the last rocket ship to the moon, and got caught up in a swarm of zombies 'caus they do that. Now you have to hold out diverse locations that he got to somehow. I don't know, he jumped? Watch the matrix and assume Bob can do that to. Anyway, luckily for Bob, he had a shotgun in his colon when he missed the rocket so he can just shoot the living hell outta them. He also can survive multiple puncture wounds because he is Chuck Norris' second cousin. Oh and he's resistant to the infection because... because... because he is. He took his Swine Flu injections. There we go, everything is explained. Now wasn't that fun.

Grave Matters is being developed by me and an unfinalised mapper (I'd rather get a freind for that if I'm honest). We have a modeller, texturer, one of two mappers and map debugger, but we are looking for a coder and a bunch of playtesters. If you can code, or if you deem yourself a good game critic, contact us, we'll be more than happy to have you on board.

The zombies are very much like antlions, if you care to imagine that, but with custom models, textures and animations. They do not fly, but jump (hence moonboots). They do not burrow, rather leap out of the ground, and so on and so forth. The mod also includes new weapons and will, at some point after the first beta, have multiple zombie types. The types under consideration are as follows:

Classic: Regular old moonboot-toting zombie. This zombie will be available from the first beta
Heavy: Too large to accomodate the moonboots of his classic companion, and therefore floorbound, but he packs a punch and a half! The moment you're on the floor, he'll charge at you and punch you into the next century! Certainly one to avoid!
Ninja: Have to be careful of this one, as he is totally invisible! He may do a considerable amount less damage than the classic, but if you arn't alert one can take you down. Lucky for you he makes a distinctive screech when he's about to come down on you. Like a flannel.
Spitter: Much like the Classic, but this baby has a secret weapon! Spurting from his mouth like a majestic volley of impending doom come poisoned spikes! If that was not all, he will also explode violently on death. Probably because he drinks petrol. Or something.

Anyone kind enough to submit concepts for the heavy or spitter will be greatly appreciated, and we will specifically mention you in an announcement. This does NOT go for anything that either is a copy of someone else's work, unfitting in the project, badly made, or a combination of any of those 3, and we will cast you aside and may look worse upon future submissions by you. It does, however, go for ideas for new zombies, as long as they are not too complex (due to the lack of a coder, we are using barely modified versions of the base hl2 npc ai), so try to base your ideas upon hl2 npcs. New models and animations are fine though, as we have a very able modeller who can quite easily do most models in this style. The first, custom model-less alpha will be released within the week to test gameplay, but only to designated playtesters, so get your name on the list quickly!
