A blog post by Bethesda announced that battle royale mode would be removed in September to allow the team to focus their work elsewhere.
The statement said: “When we first introduced Nuclear Winter, a large number of new players joined our community. We were excited to see increased participation in Battle Royale mode. However, over time, players began to switch to the other direction instead of this mode.””
After a troubled start, various improvements and bug fixes were introduced to the game for a while. But that wasn’t enough for the players. After the cancellation of Battle Royale mode, the team will evaluate this situation in another game mode.
