Ubisoft has announced that the The Escape from Durgesh Prison DLC for Far Cry 4 is now available. The DLC Is available on all platforms for $10 ($0 if you have the game's season pass.) Escape from Durgesh Prison can be played either solo or co-op, but the catch is that you only have one life. If you die, you have to start over.
The goal is to have the fastest escape time. There are also leaderboards that track your stats. Ubisoft has posted a small walkthrough video for the DLC that can be found below.
