Nightmare Horde Mode These other upgrades follow the Avatar update for Brawlhalla and the week-long Valhallentine’s 2023 event, which included a Valentine’s Day update with a number of new skins and other love-themed enhancements. Nightmare Horde Mode was unveiled the day following Valentine’s Day. The move from Valhallentine’s 2023 to the new Nightmare Horde Mode is both abrupt and amusing, reminding players that Brawlhalla is a game about beating up other players rather than falling in love. Brawlhalla’s new well-timed game mode will undoubtedly delight and challenge gamers. If players love Nightmare Horde Mode, other tougher game modes may be added in the future.
