MTX Mototrax Demo / Tony Hawk's Underground Cheat Codes? Demos Don't Have Them

Demo versions do not include cheat codes. They're stripped-down builds for preview purposes—cheats would defeat the demo's goal of showcasing core gameplay.

Full Game Cheats (For Reference)

• MTX Mototrax (PS2/Xbox/PC): Enter at main menu → "Cheats" → codes like UNLOCKALL, MOTOCROSS, FREESTYLE (varies by platform)
• Tony Hawk's Underground (PS2/Xbox/GCN/PC): Pause → Cheats → e.g., always_special, perfect_balance, unlock_all_levels

If you own the full game, check the in-game cheat menu or GameFAQs for verified lists. Demos? Just play the levels provided.
