Unlike previous entries in the Fallout franchise, this November's Fallout 76 is a multiplayer-focused, always-online game. Bethesda plans to release free DLC to keep people coming back as part of the game's larger games-as-a-service model. But how long will the game last? According to Bethesda marketing executive Pete Hines, until the end of time.

"Forever," he told Metro when asked how long he envisions Fallout 76 lasting. "I'm not being ironic. Like, forever."
