A free trial of Call of Duty: Black Ops 2's first DLC pack Revolution will be available to Xbox 360 users this weekend.

The free trial, which goes live at 6pm BST tonight until Tuesday, May 28, gives those who haven't yet purchased the expansion pack to 'try before you buy', and is expected to offer players full access to the four multiplayer maps and additional Zombies 'experience'.

The trial will not be available on PS3 or PC.

Black Ops 2: Revolution launched on Xbox 360 back in January, before launching on PS3 and PC a month later.

The latest expansion pack, Black Ops 2: Uprising launched on 360 last month and PS3/PC last week.
