may be the sixth in name, but it's the eighth in the main series (not counting spin-offs or ports). This latest video demonstrates campaign co-op play and the kind of teamwork, hazards, and combat that dynamic duos will face as they team up to tackle the zombie threat.
The game will feature three core characters
across three unique campaigns. Each character will have individual co-op comrades and the three stories share key plot points as story arcs cross over revealing more detail as to how previous events led to certain scenarios.
Don't forget, there's a demo set to hit Xbox LIVE
on September 18th, with the full title debuting in stores from October 2nd.
