In January, Playstation 3 owners will receive an exclusive DLC titled "High Tides". This DLC is adds some more content to the co-op mode in Far Cry 3.
The High Tides DLC will add two new chapters to the co-op mode, Jailbreak and Redemption. Ubisoft claims that these two chapters will "feature the culmination of all the hard work, they've implemented in the co-op campaign."
The High Tides DLC will take place where the original co-op characters left off, marking their final moments. The DLC will feature bigger fights, new missions, bigger competition and more explosive moments than we've seen before. I have yet to play to the co-op mode myself, but judging by how good the campaign was, I don't doubt that co-op will be anything less than great.
