Two final downloadable content pieces to add to a great puzzle of add-ons over the year are to be arriving soon for MW3, after they had their times of released announced. That will be started by Collection 3: Chaos Pack & Collection.
This pack will release on August 9th. Then, on September 6th, Collection 4: Final Assault is also set to arrive. These are of course, release dates exclusively for Xbox 360. Other platforms will get them not long afterwards.
There will be a new Special Ops Chaos Mode in Collection 3, along with three new FACE OFF Maps, as well as four new Spec Ops Missions. A last batch of five multiplayer maps are to be released in Collection number 4.
