They have a playable version of the first quarter of the game ready! I highly recommend you give it a try, I know I will!

It looks like they need some help with 3D modelers. If you’d like to help him out, the guy included his email address!

PS: oh, it looks like you actually have to have bought the game or have a copy of it on your computer. I’ll keep looking for places you can download it, it’s worth the trouble.
