Capcom released an unannounced update for Ultimate Marvel vs. Capcom 3 on Steam on June 15. The patch introduced bug fixes and Windows 11 compatibility but accidentally disabled the Dark Phoenix mechanic for the character Phoenix.
The update marks the first patch notes for the game since 2017. It fixed the long-standing Kubota Escape exploit but introduced a new issue where Phoenix can no longer transform into Dark Phoenix even with a full Hyper Combo Gauge.
Players reported that the change stems from an altered code check requiring more than five bars of meter, which exceeds the maximum. Other bugs, such as Frank's zombie plungers, remain unfixed while several community mods broke due to the update.
Community members on Reddit and Discord expressed frustration over the accidental removal of a core mechanic. Capcom has not yet commented on the patch or announced any plans for a hotfix.
