Titled Old World Blues, the add-on will be available simultaneously for PC, PS3, and Xbox 360 on Tuesday, July 19th. With this add-on being pushed back, the fourth add-on Lonesome Road will most likely be pushed from its original July release schedule.
The base game will see an overall update prior to the release on Old World Blues that brings improvements to performance and stability in major areas according to Bethesda Blog.
Old World Blues has players being forced in partaking in a gruesome science experiment that also offers a closer look at the Mojave’s mutated monsters. Players will also have to choose to either battle the scientists or join them to fend off a bigger threat. The add-on will add five new levels for the player to gain and new opponents to battle. Also, Old World Blues will let players keep their equipment unlike the other expansion.
