Not that there's a sizable audience that still plays
Gearbox Software's hero shooter meets MOBA hybrid thing
Battleborn. But, it's still disappointing to hear that online titles with single-player components can cease to exist.
In the case of Battleborn this means removing the game from storefronts, putting an end to virtual currency sales, and then in January 2021 switching off servers.
With publisher 2K Games noting, "The game’s servers will remain active and the game will continue to be playable until January 2021. However, once servers are deactivated, Battleborn will no longer be playable."
And this extends to the single-player story-driven campaign too, which will also become unplayable. So yeah, no Battleborn past the title screen as of 2021. The first phase of the sunset plan, which includes removing the game from sale has already happened.
