Basic model I put together a while ago for testing with (simple poorly put together humanoid with gun, animated with idle, walk, shoot and death animations, b3d format) Use or don't use for whatever you want. I've got quite a few things like this that I'd be willing to supply if all you are after is some low quality placeholder graphics...
