Grand Theft Auto IV (weapons)

Before using cheat codes

You cannot enter any cheat code before your cellphone really works. Thus, you have to succeed the 2 first missions in order:

1) Drive to Roman's Place mission.
2) It's Your Call mission: go to see Roman at the cab depot, drive him to the hardware store, then back to the cab depot.
3) Now your cellphone works. Let's cheat!

CHEAT CODES

1) Press Up to display your cellphone.
2) Press Up again to access the keypad.
3) Enter the following numbers to activate the corresponding cheat code. Press A to call.
4) The cellphone calling, then ''Cheat activated'' displays and the phone hangs up. The cheat is on!
5) Once you enter the first cheat code, the new ''Cheats'' menu appears under the ''Options'' menu. You can now access the cheats by just validating the corresponding cheat's name.
6) Save the game to keep the cheat codes in your phone. But carefull! As in all GTAs, saving after enabling a code can cause some problems. Note that this may disable some Achievements. A message always indicates the blocked Achievement(s).
