Call of Duty: Black Ops 2's first DLC pack 'Revolution' is free-to-play on PS3 this weekend, courtesy of developer Treyarch.
MP1st reports that the free trial lasts until June 24.
To grab it, simply head to the Black Ops 2 in-game store and choose 'Revolution Free Trial'.
The pack includes new maps Grind, Mirage, Hydro and Downhill, as well as the new Peacekeeper SMG weapon and Zombies map Die Rise.
I appraised the Revolution DLC when it hit Xbox 360. You can check out what I thought here.
