Title Update 1.07 was released on September 12, 2011 for the Xbox 360 and PlayStation 3 versions of Red Dead Redemption. This automatic update is a requirement, and without it the player will be precluded from utilizing the Myths and Mavericks DLC released the following day. This update also addresses issues as detailed below. Players will be prompted to apply the update when starting the game while an Internet connection is active.
Undead Overrun - Restores original settings, with an additional change to help players:
Restores extended sudden death and removes explosive retcher spit. Returns maps to original (expanded) boundaries. These items were initially changed by Title Update 1.06.
The addition of an option to exit Undead Overrun without sacrificing XP. From Rockstar's support site: Due to community feedback, we will be changing Sudden Death back to the way it was [...]. Extended sudden death will be back, explosive spit will be gone, and players who have already died will have the option to keep their XP and quit out of the game if someone is prolonging Sudden Death by running around or camping rooftops.
Fix for exploit which resulted in use of weapons from Undead Overrun in Free Roam.
