Ubisoft have revealed their plans for upcoming Far Cry 3 updates. Changes will include a new difficulty mode, extended custom map features and, most interestingly, the option to reset all of the game's Outposts. Available after completing the game and capturing all Outposts, the reset option will let the pirates move back in, causing each one to become hostile again. It's not quite as elegant a solution as the PCG podcast's Eternal Twist DLC idea, but is still a welcome extension to Far Cry 3's best bit.
Also incoming is the harder Master difficulty setting. According to the game's community manager, "Seasoned veterans will find themselves challenged by more aggressive wildlife, tougher pirates, and more deadly privateers. Your skills as a master of the Rook Islands will be tested."
Finally, changes are incoming to multiplayer, too. Specifically to how you find custom maps. A new rating system will let you give feedback to user-rated battlegrounds, including an overall rating as well as specific ways in which you think a map could be improved. Map authors will also be able to beta test maps, allowing them to spectate while testers fight it out.
