We remember the original Rainbow Six: Vegas game being reasonably pretty. Bloom lighting cast by neon tubes that lit detail-filled environments.
So what's happened here then? Visually the sequel should have matured like a pair of socks left to fester under the bed. But look at the blurry textures on walls (when the camera gets close enough), the bland lighting, the last-gen-style smashed glass and explosions, and the jagged low-polygon environments. It's not far off an old Xbox game.
See what you think in this in-game trailer, which is intended to show off the co-op gameplay, to the right.
