Meccha Chameleon v2.5.1 Patch Notes — Anti-Cheat & Osaka Bounds Fix

Official v2.5.1 hotfix: counters fake recommendation and rapid-fire cheats, and fixes Osaka map out-of-bounds exploits.

By MecchaGuide Editorial Published Updated · verified v2.7.0

Summary

v2.5.1 was a July 2026 hotfix after v2.5.0. The live public branch is now v2.7.0 (Egypt map + random-map toggles). This page documents the v2.5.1 anti-cheat and Osaka bounds fixes.

Confirm the build string on the title screen matches your lobby. Official wording: Steam news hub.


What changed

1. Anti-cheat — excess recommendations

Players could abuse systems that grant an excessive number of recommendations. v2.5.1 adds server-side countermeasures so lobbies stay fairer and scoreboards are less polluted.

2. Anti-cheat — rapid-fire

Rapid-fire cheats (actions firing faster than intended input) are blocked. Legitimate paint / tag cadence should feel the same; only exploit pacing is targeted.

3. Osaka — out of bounds

Fixed cases where players could leave the playable Osaka area. Community OOB routing from early v2.5.0 sessions needs a retest.

Player checklist after updating

  1. Restart Steam and confirm v2.5.1 on the main menu.
  2. Host a new lobby (do not reuse old rooms across versions).
  3. If friends cannot join: Invite Not Working or Version Mismatch.
  4. Playing Osaka? Retest corners and vertical routes after the bounds fix.
