Fallout 4 will be free on Steam and Xbox over the coming weekend. The Xbox promotion is reserved for Live Gold members. Interested members and Steam users will have access to the base game as well as be given the opportunity to try out some mods.
The free trial period for Fallout 4 will last 25 - 28 May for PC via Steam and Xbox One. The game will be discounted on the two platforms as well as on the PlayStation Store during this free trial period. There is no mention of a free weekend for PlayStation 4 in Bethesda's announcement.
For those few gamers that missed the title since its launch back in 2015, this is quite a unique opportunity to see for themselves what all the fuss is about. The promotion will include the game's base content and allow access to community mods.
Fallout 4 was received quite well critically, and had a mixed reception among fans. Regardless of its reception, the game sold exceptionally well, and has spawned 6 DLC packs since its release.
