G'day mate,

Top-down sprites of zombies and/or humans were what you were after, am I right?

After a quick Google search I found a thread on another website asking for the same thing, and suprisingly enough they were provided with a large amount of sprites and tilesets. 

I'll write here that, although these sprites were posted for pubic usage on a public forum, I'm sure the poster of the artwork (llama man mostly, unless you decide on using JWRAC's sprites posted also) wouldn't mind a bit of recognition and/or consideration afterwards. ;-)

Here's the link: http://gmc.yoyogames.com/index.php?showtopic=553529

I would also like to ask whether or not you'd be up for perhaps taking on a group project with this game online as I believe together we could progress it much further than only one person could, and being a lone wolf can sometimes hold you down with some heavy weight upon your shoulders at times during the creation. (My experience with video game creation varies from all different ranges from simple top-down RPG's to a rather complex shooter/platformer).

Hopefully you will consider this offer, however, if not, good luck on your project!

Cheers, ~pa1indr0m1c
