I can't wait to try this demo out!
Ubisoft has today announced that a single-level demo of the forthcoming title Rainbow Six: Vegas will available to download from October 23rd via Xbox Live Marketplace. The level, which features part of the "Dante's Casino" mission, will demonstrate the OPA (Observe, Plan and Assault) strategy in the game, as the counter-terrorist team hunt down the leaders of the terrorist cell.
