Activision released this latest behind-the-scenes look at Call of Duty: Black Ops focused on the upcoming "Rezurrection" DLC release. The primary focus here is on the "Moon" map, which sounds like it could be terribly good fun to play if only to see how the change in movement speed and control causes people to change up their tactics. I would think that it won't really offer much of a disadvantage to snipers.
Military shooters aren't my thing, but sci-fi shooters with zombies totally are my thing. Bit late for me to be jumping on the Black Ops wagon, though.
