Looks like they're kinda going with the Starcraft model of upgrades. Make it sharp, make it detailed, make it pretty, don't go for photorealism. That's fine with me. Of course, the real test will be making it look good in motion. I can't wait to see that.
Edit: Scratch that a little. Looking at the high-res shots, they're going pretty insane with the bloom there and blood effects. Pretty awesome, even if it's almost too much bloom.
So far, the best news is there's totally a
beakie in one of the pictures. I'm so sold.
