What is mecchaonyx?

MecchaOnyx describes itself as a hack tool built for a hide and seek style Steam game called Meccha Chameleon. According to its README, it adds features like seeing other players through walls, automatically aiming at opponents, flying around the map, teleporting, becoming immune to being caught, and having unlimited use of the in game paint mechanic that the game is built around. The README lists its features in four groups. Visual features let you see enemies through walls, show distance and health information, and highlight players with on screen markers. Combat features aim at enemies automatically, including a silent version that does not need you to actually look at the target, plus automatic firing and removal of weapon recoil. Movement features let you fly, teleport, and move faster than normal, ignoring gravity. Protection features make you immune to being tagged, give unlimited paint, and let you change the match timer. To use it, you download a packaged release, extract it next to the game's install folder, run it as an administrator, launch the game, and open an in game menu with a keyboard shortcut to turn features on and off. It only supports 64 bit Windows 10 or 11 and needs modest amounts of RAM and storage. The README also describes techniques meant to keep the tool from being detected, including automatically updating internal memory offsets, randomizing behavior to look more human, and injecting itself without leaving an obvious signature. A troubleshooting table covers common problems like antivirus software blocking the tool or the game crashing. Tools like this modify a live multiplayer game in ways the game's developers and other players do not expect, and using one typically violates a game's terms of service and can get an account banned. The README itself only calls the tool educational, but its actual described purpose, giving one player an unfair advantage over others in matches, sits outside that framing.
