There are new achievements and avatar awards to sink your teeth into, too.
A trial version of the DLC is available, which gives you the complete Capture the Orb mode and a single-player version of Deluge for free.
Crackdown 2, from Ruffian Games, was released mid way through the year and scored an impressive 8/10 from Christian Donland.
