No official cheat codes exist for Metal Arms: Glitch in the System on any platform (PS2, Xbox, GameCube, PC). The game was designed around tight combat and platforming without built-in cheat menus.
Speedrunners and enthusiasts have found a few glitches, though they require precise execution:
These are unintended, version-dependent (often patched in Greatest Hits/Platinum releases), and not reliable for casual play.
The game's difficulty is core to its design. Overcoming its challenges provides the intended satisfaction. No trainer or mod can replicate the feeling of mastering its unique combat flow.
