The cerebral third-person shooter, Spec Ops: The Line, has officially received a free downloadable content package, including a cooperative multiplayer mode. The mode is separate from the main campaign, and will support only two players, but includes four brand new missions with unique objectives and different characters to fight through the sandstorm-ruined Dubai with. You can expect some pretty standard fare here, including wave-based objectives where you’ll be pitted against the elements and a whole bunch of enemies, alongside others. The content is available now on Xbox 360 for the wonderful price of free.
