Hi I just tested the game - Fantastic work. I only have a minor complaint: The vehicles, at least the Space Marine ones (Rhino + Land Raider) are waaay to small. The Rhino is lower than you Point of View, and the Land Raider would never be able to carry 12 Marines.

So I think you should upscale them a bit.

Here is a good reference, you can see a Space Marine manning the stormbolter: http://wh40k.lexicanum.com/mediawiki/images/a/a4/LandRaider.gif

Here you can see the the Land Raiders ramp is even higher than a Space Marine:

And here a Predator (same chassis as Rhino): You can see that the Marine is smaller than the tank, even with his jumppack. He would fit easily through the open ramp: http://s7.directupload.net/images/130429/5yau5lkh.jpg
