Ubisoft announced in December that the PlayStation 3 version of Far Cry 3 would be getting an exclusive digital downloadable expansion called High Tides. Now the developer has announced that the new DLC will officially release on Tuesday Jan. 15.

The new expansion will add new content to the game's co-op campaign that takes place after the original chapters of the co-op mode. The new co-op chapters, Jailbreak and Redemption feature the final moments of the game's co-op characters.

The High Tides DLC will also be free for PlayStation Network users. Here is the original PlayStation blog announcement regarding the add-on:

"Hey, gamers! The studio that brought you Far Cry 3's online experience is preparing something big to kick off the new year: the co-op DLC pack, High Tides, exclusively on PS3 for console gamers. This January, we're releasing two entirely new co-op chapters, Jailbreak and Redemption. These new chapters feature the culmination of all the hard work we've put into the main co-op campaign.

High Tides will take place where the original six co-op chapters left off. These are the gang's final moments, and we're really challenging ourselves to go all-out. We've got new missions, tougher fights, bigger competitions, some great up-close time with your favorite characters, and explosive moments unlike anything you've seen before. Can you tell we're excited?

We want everyone who loves Far Cry 3's co-op to get even more quality time with the whole gang - Leonard, Tisha, Mikhail and Callum. So pick up your copy of Far Cry 3 for PS3 today, and find out in January what happens when the gang tries to escape the island in these final chapters."

The cooperative campaign mode features four player-controllable characters; Callum "the Scottish Thug," Leanard "the Crooked Cop," Mikhail "the Russian Hitman," and Tisha "the Ex Soldier." The plot of the coop mode takes place six months before Jason Vandenberghe's search for his girlfriend and centers around the aforementioned foursome being scammed out of money by pirates. The four then pursue the pirates to the island in search of revenge.

Far Cry 3 is now available worldwide for Microsoft Windows, Xbox 360 and PlayStation 3. You can check out our review round up for the game here and our list of the game's five best trailers here. Learn more about Far Cry 3' multiplayer and co-op modes here.
