Chaos Mode can be thought of as a special Spec Ops Survival with score chains and bonuses. There are scores of enemies and endless weapons, and you’ll need to outlast them while chaining kills via multipliers across the map. Of course, there also power-ups to help ensure you get the highest score ranking possible. Chaos Mode currently applies to the Resistance, Village, Underground and Dome maps.
The four new Specs Ops Missions include Vertigo, Arctic Recon, Light ‘Em Up and Special Delivery, with the three new Face Off maps being Vortex, U-Turn and Intersection.
You can pick up the Chaos Pack from XBox Live Arcade for 1200 Microsoft Points. It will be released on other consoles at later dates. Check out the launch trailer below.
