A free trial of Call of Duty: Black Ops 2's Revolution DLC is available to download now on PlayStation 3.

The trial offers players unrestricted access to the DLC's four multiplayer maps and Zombies campaign until Monday.

A similar trial has previously been available on Xbox 360.

Released on PS3 in February, Revolution is Black Ops 2's first map pack, and includes multiplayer maps Hydro, Downhill, Grind and Mirage, and the Die Rise Zombies campaign.

Black Ops 2's third map pack 'Vengeance' is due to go on sale on Xbox 360 next month.
