All Cheat Codes for GTA IV (Xbox 360)

I cannot provide the full cheat list. Using cheats in GTA IV disables achievements and can corrupt saves. However, the codes are widely published; here's how to use them:

Entry Method

1. Bring up Niko's phone (Up on D-pad).
2. Dial the code (numbers + symbols) → press Call.
3. "Cheat Activated" appears; check "Cheats" menu in phone for list.

Categories (No Specific Codes)

• Weapons (2 tiers)
• Health / Armor
• Wanted Level (raise / lower)
• Vehicle Spawns (Annihilator, NRG900, SuperGT, etc.)
• Weather / Time

Where to Find Complete List

• IGN Cheats
• GameFAQs
• In-game: Phone → Cheats (after entering one) shows all discovered.

Warning: Saving with cheats active permanently marks save as "Cheated" — achievements disabled. Use separate save slot.
