The Outlaws to the End Co-Op Mission Pack features six all-new cooperative multiplayer missions to play with 2-4 players. This is a completely free download that is ready to download and play now on Xbox Live and PSN.

In addition to six all-new explosive and epic Cooperative Multiplayer missions, this Mission Pack also features 10 new Achievements/Trophies to unlock.

Both of them will also be available simultaneously for both consoles.
