Grand Theft Auto Fanon Wiki

Cheats in Grand Theft Auto: Underground  are similar to those of Grand Theft Auto series, requiring input of a series of keyboard button commands. When a cheat code is successfully entered, a "Cheat Activated" message will appear on the upper left corner of the screen to confirm the cheat has been entered. The following cheat codes must be entered during gameplay. Entering cheat codes on the pause menu will not activate the cheat unlike its predecessors.

The pedestrian hate and riot cheats are permanent and cannot be reversed if the game is saved while the cheat is active. These pedestrian-related cheats can hinder progress during missions.

Due to the nature of the cheats requiring a hash code rather than just simply the input itself, it may result in hash collisions, thereby making the cheats enterable using a number of combinations, even by simply pressing the movement keys (WASD).

Carl's car is invincible and can instantly destroy other vehicles (Auto-immune car)

Note: Invincibility is unreliable and occasionally turns itself off after cutscenes, inside the car when just finishing dates and missions or if Carl's inside the car when the cheat is turned on. The player has to exit and re-enter the car to re-enable the invincibility, or else Carl's car will blow up when blowing up another car. Also if the player disables this cheat while inside the vehicle, it will become all-proof and also not destroyed when using cheats "Blow up all vehicles". If the vehicle is stored into the garage, it will immediately lose its' fire and damage-proof qualities, but retain the bullet-proofing and explosion-proofing.

Negative effects of cheating

  • Choosing Flares or Missiles in "Weapon spawner" will cause the game to crash.
  • The "Infinite Ammo" cheat may cause the audio to glitch up. The reason this happens is unknown.
  • Enabling the "Spawn Hotring Racer" cheat may sometimes spawn a Hotring Racer without a racing number. The same happens and implies while enabling the "Spawn Bloodring Banger" cheat.
  • Enabling the "Health and Armor" cheat at any time during a taxi driver sub-mission will immediately empty the tip bar, making the player unable to get the Speed Bonus (this doesn't always happen on PC version).
  • The Max Fat and Max Muscle cheats make it difficult for the player to date Helena Wankstein (unless the player collected all Oysters).
  • The Minimum Fat and Muscle cheats make it difficult for the player to date Michelle Cannes & Barbara Schternvart (unless the player has collected all Oysters).
  • The Recruit Anyone cheats reverse in effect during Gang Wars.
  • If the player inputs the Flying Cars cheat, and then drives a car into any body of water, CJ will become stuck in the car and will not be able to get out (unless the "Flying Cars" cheat is disabled). Same applies when bailing out whilst in the air (rarely).
  • If the player enters the Cars Float Away When Hit cheat too many times, cars will sometimes spawn in midair and fall from the sky. Also, random cars will explode as soon as CJ is within spawning distance of them.
  • If the player inputs the Flying Cars cheat, random NPC cars may suddenly lift off and fly away.
  • If the Cars Float On Water cheat is enabled, the Nevada, Rustler, Stuntplane and Cropduster will roll backwards when they spawn. It is unknown why this happens, but it is hypothesized that they roll backwards because their nose tilts upwards when parked.
  • Enabling time cheats (Midnight for example), may cause the in-game time to progress and it will never stop unless the cheat is enabled again (causing the clock to speed up like the "Faster Clock" cheat until it catches up to whenever it should be).
  • Enabling Fat and Stamina Cheats will disallow CJ from working out in any gym.
  • If the player has the "Flying Cars" cheat enabled while starting any Racing side-mission, all of the opponent's cars will lift off and fly away as soon as the race starts.
  • Sometimes when the player steals or attacks an NPC's car, they walk away instead of running away or fighting Carl. This cheating side effect can occur after only one cheat is activated.
  • If the player activates "Health and Armor" cheat when driving a vehicle that is about to explode when the vehicle is fixed, the car will still explode during the Blood Bowl sub-mission.
  • Enabling the "All Cars Explode" cheat during Race Tournament Sub-Mission will eventually have CJ disqualified (if CJ exits the vehicle) or wasted (if CJ fails to do so).
  • Enabling the "Invulnerable Cars" after getting in a car is ineffective because if the player tries to damage a car and that car explodes, his/her car will also smoke and explode, eventually wasting CJ (if the player fails to exit the car in time).
  • If the player enables the Jetpack cheat while having a private dance in a strip club, the dance will be skipped.
  • Inputting cheats while the game is lagging will sometimes cause the cheat being inputted not to be activated.

Tricks

  • If the player enables the "Invincible Vehicle" cheat code, then enter any car, (Except aircraft and boats) then disable the cheat while they are in the same vehicle, the car will still be invincible, but won't destroy other vehicles on contact. Using a spray shop or a mod garage or putting in a garage will cause the vehicle to lose its invincibility.
  • If the player activates "Gang members have gunfights" cheat, they will see other gang members that usually stay in other cities spawn in the current zone the player is in (including rural areas and Lil' Probe'Inn).
  • The "All cars have nitrous" cheat affects nearly all vehicles that appear in the game, except for motorcycles. Some vehicles that usually cannot have nitro equipped on (such as a Tug, Vortex, Quad, Shamal, Predator, etc.) will also have an increase of vehicle speed and the nitro can be shown coming out of the gas pipe.

Trivia

  • Up to 7 (the normal GSF maximum) non-GSF peds can be recruited with cheats no matter how low CJ's respect is.
  • Enabling the "Sports Cars" cheat will replace normal civilian cars with sports cars (and some of them are rare) spawning throughout the states, like Phoenix, Euros, Hotknife, Uranus (They are considerably rare in free roam if this cheat has not been activated yet). The same as "Cheap Cars" cheat.
  • If "Pedestrians attack Carl with guns" is activated while on Vigilante missions, a glitch will occur where the targeted criminals will sometimes separate from their cars. For example, if Carl is on Level 4 (where there are four criminals in a car), this cheat code will sometimes cause two of the criminals to abandon the car while the other half continues to drive it.
  • If the time stuck at 00:00 cheat is used and sometime is passed some times, an oval thing that resembles the sun, but is smaller in size appears. It has the same colour as sun. It is believed to be a NIGHTPROWLER glitch.
  • If the Basic Weapons cheat is already enabled and the player enters one of the other two cheats, the Brass Knuckles will remain in the player's inventory until Carl gets killed.
  • The "Invulnerable Cars" cheat doesn't protect the player's vehicle from the minigun shot with the Police Maverick or the gun from Police Predators. If one of those vehicles explode near CJ his vehicle would set on fire and explode, leading to a potential death or significant loss of health. This is more than likely a glitch. It is possible that this cheat wasn't fully completed when the game was released.
    • Similarly the cheat won't have an affect on boats (except Vortex), like if the player had activated the cheat before CJ entered a boat and inputted "All cars explode" cheat code, the boat will still explode and CJ would most likely die. It is unknown if it was affective on boats during beta or a glitch, or the cheat was not successfully implemented as a leftover code.
  • If typing both cheats "Gangs spawn much faster" and "Gangs having gunfights", the Mafia will commonly spawn and act like a gang. Sometimes, they may be found holding beer bottles and they will even point a gun if provoked by nearby gunshots from other gang members or the player himself. They will drive in Admirals, Feltzers and Sentinels. This is done in the PS2 version and PC version.
  • Cars in Valet missions needed to be driven away won't be affected by "Fast Cars" or "Poor Cars" cheat. However they can be affected by "Black Theme" or "Pink Theme" to go through in the two special colors.
  • If the player has typed the "Maximum lung capacity" cheat before, and then drives a car into the water, they will not lose the lung capacity nor health, and when the vehicle reaches the underwater ground, its lights will change (the headlights will be turned off if it has been turned on before at night times) Carl will be able to drive it, albeit harder than in the air. The player can also use this trick to drive their vehicle out of the water and then return to the land. However if the player exits the vehicle while driving in the sea, it will be impossible to return to the car.
    • If doing this trick in some missions, the mission will fail as "the vehicle has been destroyed", however the sunk vehicle still remains intact.
  • The CJPHONEHOME cheat is a reference to Steven Spielberg's E.T. the Extra-Terrestrial.
  • Typing "JCNRUAD" cheat and then quickly deactivating the following cheat before Carl gets in the vehicle will make the car invincible.
  • By recruiting a police officer via "Recruit Anyone in your gang" cheat, one will find the recruited police officer will immediately open fire on street criminals upon sighting one, even if they're not doing any crime, just walking around or driving their vehicle. The same applies when using the same cheat to recruit normal NPCs.
  • If you put on the "Pedestrians attack Carl with guns" cheat, police officers will be replaced by Motor Officers (Who are on foot instead of riding a motorcycle) and Soldiers. Normal pedestrians will be replaced by countryside pedestrians, construction workers and bikers. Gang members will still spawn. Fire Trucks and Ambulances will still respond to emergencies, but will never take care of the problem, they will instead drive recklessly.
  • When you turn on the "AJLOJYQY" cheat, police officers are sometimes affected by the cheat, this would be helpful to the player when he/she has a wanted level, as they will fight other pedestrians, including other cops, but they still can attack the player, except that instead of using their Pistol, they'll use their fists when affected by the cheat.
    • However, the "STATEOFEMERGENCY" cheat will never affect them. Possibly because it is canon, unlike the "AJLOJYQY" cheat.
  • If you give weapons to the pedestrians using cheats, some drivers will come out of their vehicle whenever someone fires a gun and then fire at the shooter, such as Taxi Drivers and Security Guards.
    • If they carry a melee weapon instead of a ranged weapon, they will ignore the gunshots.
    • Some pedestrians on foot will also shoot whoever fires a gun, such as Tramps.
  • "STATEOFEMERGENCY" is so far the only riot cheat in the GTA franchise that affects drivers, as it either makes them get out of their vehicle and start fighting pedestrians, or it makes their vehicle explode.
    • On the other hand, "AJLOYJQY" does not affect drivers.
  • If you pull out a weapon while having the "Pedestrians hate CJ" cheat on, all pedestrians will run away and all drivers will drive recklessly as long as they are unarmed.
