The actual materials that will make up the expansions for Fallout 4 were not initially established due to Bethesda focusing all of its efforts on ensuring the base game's launch is successful. Recently, the Maryland-based studio revealed that Fallout 4 will indeed have a Season Pass and DLC sometime post-launch, but perhaps the most welcome news came from Bethesda's later confirmation that the DLC will not be platform exclusive.
Ever since the official announcement of its existence during Bethesda's first-ever E3 2015 press conference, fans of the post-apocalyptic RPG franchise have continued to clamor for any new information regarding the game on a daily basis. Fallout 4 is arguably the most anticipated release of 2015.
