New maps, new spec ops missions and a new multiplayer mode is set to be included in this bundle.
The new multiplayer mode is called “Face Off” the maps will heavily focus on small battles, you will always have a sightline to look to and always be in the action, as the maps are smaller than the standard maps you will only be able to play 1v1 or 2v2 battles on these maps.
The Face Off maps are Aground (a beached ship off the coast of Scotland) and Erosion (Ruins off the coast of Italy below an erupting Mount Vesuvius), will release for free on 15 May, ahead of the full release. There are also two other Face Off maps that will be included in the content collection itself, Getaway (a beachside mansion) and Lookout (an observation post in Afghanistan).
On top of that there are three standard mutliplayer maps included also Foundation (a Korean cement factory), Sanctuary (monastery in Greece) and Oasis (coastline in the United Emirates). Both Foundation and Sanctuary have already been released through Call of Duty Elite.
And finally we have two more spec ops missions, Ironclad from the campaign where you and another have to help pave the way for a tank division, this mission also includes the ability to drive a tank, and Killswitch that is set in Russia where one you will provide sniper support and the other player will be on the ground where eventually you will set off an EMP device.
Content Collection #2 is set to release 15 May for Elite subscribers and 22 May for everyone else on Xbox 360, the PC and Playstation 3 release is still unknown at this time.
