The October update, dubbed "Total Payback," will add cheat codes to the game. "Unlock the total-payback power of all weapons, vehicles and airstrikes in Mercenaries 2, as well as everyone's favorite: Infinite Ammo and Infinite Health," exclaims the press release.
In addition, six new playable characters will be added while removing region restrictions from co-operative play. The update will hit Xbox Live on October 13 and the PlayStation Network on October 20. The PC version of the game is already being patched, but the PlayStation 2 version of the game will have to go without updates.
Other than a November release window, no details were provided on the paid downloadable content.
