"Grand Theft Auto IV" from 2008 has a cheat code that allows players to spawn an undercover FBI police car out of thin air. The code is available for the Xbox 360, PlayStation 3 and PC versions. The police car is not only faster than many other vehicles, but it has a siren. When you use the siren, traffic immediately moves out of your way, which makes getaways that much easier.
Cheat Menu Access
The player gets an in-game cell phone after completing the tutorial mission. The cell phone is the window to the cheat menu. Press the directional pad "Up" on the Xbox 360 and PlayStation 3 to bring up the cell phone in the bottom right corner of the screen. Press the "Up" arrow on the keyboard for the PC. You will be able to type in a phone number with the cell phone open with an on-screen keyboard.
Entering the Code
Use the on-screen keyboard on the cell phone to highlight digits and press "A," "X," or "Enter" (the action buttons) on the Xbox 360, PlayStation 3 or PC respectively to enter a number. Enter the number "2275550100" then press the "Call" button on the cell phone. The phone will ring for a few minutes, then go dead. Press the "B," "Circle," or "Esc" button to put the phone away.
Accessing the Car
Bring up the cell phone again after entering the cheat and you will be on the phone's main menu. Scroll down and select the "Cheats" option, then scroll to the "FBI Buffalo" option. Select the "FBI Buffalo" option and the police car will instantly appear in front of you. It can be driven like a normal car. Click "down" on the left thumb stick on game consoles and the "H" key on the PC to activate the siren.
Use the code when you're standing in front of an empty street. If you are standing in front of a wall, the police car will spawn, but part of it may be stuck in the wall. It will not spawn at all if you are in an enclosed place like the bowling alley or your apartment. If you're on a rooftop, the car may spawn partly over the edge of a building and fall off. The car may fall into the water if you spawn it near any body of water.
