Marvel Rivals Season 4.5 released on October 10, 2025, at 09:00 UTC. NetEase estimated maintenance would last two hours, but that estimate was not a guarantee that servers would be playable at 11:00 UTC.

Season 4.5 release date and official start time

The official Marvel Rivals patch notes for Version 20251010, published October 3, 2025, give the update start as October 10, 2025, at 09:00:00 UTC. The notes estimate two hours of maintenance. The separate Season 4.5 Dev Vision announcement, published September 30, 2025, also names October 10 UTC as the start date but does not give another time.

Milestone Time What it means
Announced update start October 10, 2025, 09:00 UTC The time stated in the official patch notes.
Estimated maintenance end October 10, 2025, 11:00 UTC Arithmetic based on the two-hour estimate; not an official promise or verified server-restoration time.

How to interpret the maintenance estimate

The 09:00 UTC time is the announced start of the update process, not a confirmed time that players could enter the game. The patch notes estimated maintenance at two hours; actual availability could not be established from that estimate alone.

Use UTC as the reference and convert 09:00 UTC to your local time for October 10, accounting for daylight-saving rules where applicable. Marvel Rivals’ January 2025 patch notes provide background: starting with Season 1, the unlock time for daily missions, new store items, and most events moved from 07:00 UTC to 09:00 UTC. That schedule context does not independently establish Season 4.5’s release time.

Season 4.5 is a past release, not the current season

Season 4.5 was a 2025 update. The October 2026 official notes for Version 20261009 concern Season 10.5, which begins October 9, 2026, at 09:00 UTC. That is a separate release and should not be confused with Season 4.5.
