One More Level released the first official update for "Immortal Legacy" on all platforms on October 16, with the console version displaying version number 1.004. This patch focuses on fixing progression blockers, crashes, and graphical anomalies.
Regarding progression, the issue where progress could not be saved correctly after defeating the boss and watching the cutscene in Chapter 4 has been resolved. A progression blocker in Chapter 12, along with special cases such as cutscenes not triggering and the next lantern not unlocking, have also been fixed. Errors related to starting and advancing the side quest "In the Name of Art" in Chapter 5 have been addressed as well.
The patch also fixes several common crashes across all platforms and resolves some graphical glitches on the Xbox version. The team stated that work on Xbox graphical issues is ongoing, and players encountering further anomalies after the update are encouraged to submit feedback. An issue where Volunteer enemies stopped attacking after being backstabbed during patrols has also been corrected.
The PC version now includes a graphics driver detection mechanism, which automatically prompts users if their driver version is outdated. The developers stated that updating drivers is one of the most effective ways to improve performance and stability. This update also reduces error logging to prevent minor performance impacts in rare cases. PC players who participated in the demo or preview versions and are still experiencing performance issues can delete old game configuration files from specified locations as recommended by the official team.
