At an announcement during Microsoft’s E3 press conference, Todd Howard, game director and executive producer at Bethesda Game Studios, announced that mods on PC for Fallout 4 would be playable on Fallout 4 for Xbox One.
Later, during an interview with Geoff Keighley at YouTube’s E3 press-box he told Keighley, “[the Fallout creation kit] is not coming out at launch” and that the “creation kit is gonna come out soon after, probably very early ’16”. Also adding, “after that [the Xbox One playable mod launch] we do hope to get it on PS4.” and explaining, “we want to get this to everybody , but there’s a lot of hard work that has to happen”. The Fallout creation is also for PC only, any and all creation will be done from a PC to be played on Xbox One and later PS4, hopefully.
Howard also went into the new freedom of the game in the interview giving the example that players have the ability to start a dialogue, look away and do something else quickly, come back and finish up the conversation.
Fallout 4 is set for release November 10, 2015. Stay tuned for more details about Fallout 4 and E3 2015.
