So PS3 & PC got the "High Tides" Co-Op DLC for free now, still no word on the 360 :/
From the Steam page:
The co-op story is far from over. Hoyt’s privateers have ambushed the four survivors and taken them hostage. It’s up to you and your friends to escape an underground prison and find a way off this island of insanity.
This Free High Tides DLC Pack Includes:
- 2 New Co-op Maps: Jailbreak & Redemption
- 4 New Co-op Skins: "Warrior-ized" Leonard, Tisha, Callum & Mikhael
