At first I was very sceptical about the youtube review, but after playing the demo I have to echo the sentiments of everyone here, the demo is rougher than a bears behind.
At first I thought I had loaded up Prey, bumpmapping ahoy!.
Did anyone else notice the "effect" used on the broken mirror on the right?, rather than the mirror actually being broken, they just applied a texture on top of the surface of the mirror, everything else has height definition, that textured overlay did not.
Mechanics wise, very cumbersome... that 4x4 handled like a dead cow, and he was bang on about the AI, it just isn't there, one minute I'm being sniped, the next I'm being zerg rushed.
Oh, and the placement of that ammo crate sucked.
Gutted.
