Honkai: Star Rail is preparing for its version 4.4 update, which will introduce new story chapters and a highly anticipated collaboration.

The game will undergo maintenance on Tuesday, July 14, or Wednesday, July 15, depending on the player's time zone. This downtime is expected to last approximately five hours. Players are advised to use any remaining Fuel before maintenance begins, although the new battle pass and new relics will become available with the update, suggesting some players might wish to conserve resources.

Maintenance start times are scheduled as follows:

  • 3 p.m. PDT on Tuesday, July 14 (North America West Coast)
  • 6 p.m. EDT on Tuesday, July 14 (North America East Coast)
  • 7 p.m. BRT on Tuesday, July 14 (Brazil)
  • 11 p.m. BST on Tuesday, July 14 (United Kingdom)
  • 12 a.m. CEST on Wednesday, July 15 (Western Europe)
  • 7 a.m. JST on Wednesday, July 15 (Japan)
  • 8 a.m. AEST on Wednesday, July 15 (Australia East Coast)

Version 4.4 is expected to go live shortly after maintenance concludes, with approximate release times aligning with the end of the downtime period:

  • 8 p.m. PDT on Tuesday, July 14 (North America West Coast)
  • 11 p.m. EDT on Tuesday, July 14 (North America East Coast)
  • 12 a.m. BRT on Wednesday, July 15 (Brazil)
  • 4 a.m. BST on Wednesday, July 15 (United Kingdom)
  • 5 a.m. CEST on Wednesday, July 15 (Western Europe)
  • 12 p.m. JST on Wednesday, July 15 (Japan)
  • 1 p.m. AEST on Wednesday, July 15 (Australia East Coast)

Hoyoverse generally adheres closely to these maintenance schedules, though minor variations in start or end times can occur. Players can anticipate the servers coming online around these times.

Version 4.4 continues the Planarcadia storyline and features the addition of Himeko Nova, a new five-star playable character. This iteration of Himeko utilizes Fire damage and the Erudition path, supported by a colossal robot. Notably, Himeko Nova receives unique damage buffs when paired with other Astral Express crew members. The update also heralds the commencement of the second phase of the Fate/Stay Night collaboration, introducing Rin Tohsaka and Gilgamesh as playable characters.
