A few months back, we brought you details on Call of Duty: Modern Warfare 3's wave-based challenge, called survival mode. At the time, we highlighted our thoughts on how it plays, as well as our thoughts on some of the unlockable upgrades. If you'd like to see it in motion for yourself, Activision and Infinity Ward have a released a new trailer showing off just that.

The clip shows the same Dome level we wrote about in June. As you can see from the trailer, it's significantly different in tone and pacing from the series' now-standard zombie modes. The enemies are faster and smarter, and they play with a precision that online veterans are more accustomed to. Things ramp up quite quickly, so don't expect much breathing room once you hit start.

Look for the game when it ships November 8, 2011.
