I always wondered how they got the tape to explode. Anyway. The cheats here are very cool and they range from effects to weapons.
To input these codes go to the mission select screen and press the relevant buttons. If you do this right you will hear Ethan saying, "Ah, thats better".
The Codes For The Guns
Mini Rocket Launcher with 30 rounds - R, L, C-Left, C-Right, C-Down. This little baby turns the enemies into pastry.
UZI with 30 rounds - C-Right, C-Left, C-Right, C-Down, R. This is automatic death.
9mm Hi Power with 30 rounds - R, L, C-Down, C-Up, C-Up. This is quite a nice little blaster.
7.65 Silencer with 30 rounds - C-Up, L, C-Right, C-Left, C-Up. This is rather quite death.
The Effects Section
