To celebrate the 25th anniversary of the Fallout franchise, anyone can play Fallout 76 for free for a week.

Bethesda has announced that. The company plans to celebrate the anniversary with special events throughout the month. The free Fallout 76 week has now started and will run until October 11. Prime Gaming subscribers can also continue to play the game for free.

In addition, Bethesda must give “significant discounts on the entire Fallout franchise”. The discounts run through October 12 on Xbox and PlayStation and through October 18 on Steam. Also coming next week is a free update for the free-to-play game Fallout Shelter, which will require players to counter an alien threat in a new storyline.

The first Fallout game came out in 1997. From Fallout 3, Bethesda took over the development. The last mainline single player game in the series, Fallout 4, was released in 2015, although the online multiplayer game Fallout 76 did appear in 2018. The game was criticized on release, but Bethesda has made many new content and improvements in recent years. A Fallout television series for Amazon Prime is also in the works.
