From Grand Theft Wiki

This article is about modifying game files. For the garages that modify vehicles in Grand Theft Auto: San Andreas, see Mod Garages.

A modification is an alteration to a game. Grand Theft Auto modifications are created by fans after the game's release, and are not authorized or endorsed by Rockstar Games. Modifications can be obtained from many Grand Theft Auto websites and fansites.

Almost all modifications are entirely free, and may be downloaded and used by anybody. However, there are restrictions on editing and distributing the modification, so always ask permission from the author.

Modifications are mainly only used on PC versions of Grand Theft Auto games. There are methods of modifying console versions, but these are complex and usually break the license agreement of the game and the game console.


Different Types of Modifications

Modifications in special websites usually are distributed on several categories, depend on aspect of game they changes:

Maps - modifications of this type add buildings, islands, towns and other objects to an existent landscape of the GTA game. They consist of the added model description with corresponding textures and collision data. Examples are Pleasure Island mod for GTA Vice City and WTC Modification for GTA San Andreas.

Missions - modifications of this type alter or replace the mission script (main.scm in all of the GTA III Era games) of GTA game. These could alter details of missions or even add entirely new missions. The mission script file is responsible for what-happens-when, so modifying it can achieve almost any effect.

Patches (fixes) - modifications of this type do not change anything appreciable but only correct errors present in the original GTA game, like DFT30 missing rear wheel in GTA San Andreas and wrong placed Cuban Outfit in GTA Vice City. Some of modifications attempt to restore hidden features in game: Ghost Town in GTA III, scenes for adults in GTA San Andreas.

Player (clothing) - modifications of this type change protagonist model in game, add or replace available clothing items, sometimes also offer new animation or voice data for the player. Creation of modifications of the given type began after release of the GTA III, the first GTA game contained appreciable protagonist model. Pedestrians modifications also often appoint to the given category.

Vehicles - modifications of this type add a new cars, boats, planes & helicopters to a GTA game, or change existent vehicles colors and handling, sometimes even replace certain cars with new hi-poly modeled and textured version of them. This is a most popular kind of modifications (as also the lungs for realization), often united in large thematic packages.

Weapons - modifications of this type alter weapons models and data, like accuracy or rate of fire, and sound of shooting. They also usually provided as thematic packages.

Some modifications encompass many of these features at once - these are known as Total Conversions (TCs). TCs generally change everything in that GTA game, including the map, vehicles, pedestrians, players and missions. A few TC mods been made, and there have been many more planned that have never reached a release. Most of TCs made for the GTA San Andreas, that is explainable by the time of occurrence of ready tools for development in all aspects and growth of a community. Examples are notorious Grand Theft Auto: Great Britain, Grand Theft Auto: Criminal Russia and GTASA: Liberty City, all are still in development for the Grand Theft Auto: San Andreas.

Gameplay - Sometimes known as Script mods,this kind of mod changes the way player plays the game.This mod usually have their own custom script but didn't interfere with the main script.scm.The mod is also sometimes known as "for fun" mods because it often used to spawn the so-called "myths" in certain places,giving players special weapons,control weather,and what ever. To date,the only Gameplay mod known today are CLEO Library for GTA San Andreas. Script mods usually start the player off with maxed-out muscle, a wad of cash, all cities/bridges unlocked and sometimes with an entire arsenal of weapons to use.


Some third-party programs wrongly count as modifications. The basic criterion for modification is changing the original game 'content' files, and these programs actually do not touch that files.

Trainers - are programs that runs alongside the GTA game and manipulates the game's data stored in memory. These programs can change many different things, ranging from the player's health, armor, weapons, skill and even location; to being able to spawn vehicles, modify the current vehicle (e.g. color, damage etc) and edit vehicles stored in garages; to modifying the time, game speed and weather.

Multiplayer - As all PC versions of the GTA III Era games lacks multiplayer capabilities, gamer community start creation of unofficial multiplayer clients & servers. These programs allow to play online with other players on public servers, or offer 'head-to-head' competitions between directly connected players. Types of gameplay provided may differ between different realizations, but usually are versions of FPS-like deathmatch/CTF or rally/street races. Examples are Multi Theft Auto, Vice City Multiplayer and San Andreas Multiplayer.

Enhancers - are additional programs/libraries which remove or increase certain GTA game engine limits and restrictions, like maximum draw distance and number of objects in scene. Display of these restrictions are well known drops of road texture, delays of LOD textures on buildings when moving fast and traffic unification with current protagonist car driven. Some of enhancers also apply modern shader post-processing effects to game graphics. Noted enhancers are SA Limit Adjuster and ENBSeries tweakers.

Creating Modifications

An example of GTA San Andreas CLEO mod.Shown here are the Gravity Gun.

Some things, like car colors and handling, weapons characteristics, ped relations, can be changed easily because all the data necessary stored in plain-text files, with basic guidelines for their usage from game developers in file headers. However, creating more advanced modifications (such as entire buildings or cars) are trickier, and usually requires some advance experience in creating models for games. Google SketchUp is a good program for creating building models. 3DS Max, Lightwave and Zmodeller are also used. Textures creation is also not so simple; textures must match with specific game engine limitations and should be organized by special order into TXD files.

The mission modifications are even harder to produce. First, mission script for a game must be presented in compiled form, which require use of special compiler/decompiler tools for any changes. Second, script language is not officially documented, and worse, each script editor has their own interpretation of it. Finally, many script features depend on hardcoded functions in the game executable, which can lead to unexpected troubles with different usage approaches, game region versions, official patches and even depends on end-user hardware. These results with mission modifications are usually simple gameplay missions. The most often used mission script editor is Mission Builder by Barton Waterduck and its derivative, Sanny Builder.

For Total Conversions, there are even more specific tools needed, like ped & traffic paths editor, GXT (texts) editor, interface (menu) editor and so on. It is strongly advised that you do not attempt to do more than you are capable of. Do not expect to be able to recreate your favorite car in a few hours, many modifications take months.


Vice City Mod Manager

Vice City Mod Manager or VCMM, is a tool for modifying objects in Grand Theft Auto: Vice City. VCMM uses its own file format VCM, and mods can be downloaded in this format from many different websites.

San Andreas Mod Manager

There is another mod manager for GTA: San Andreas. It does the same thing as the Vice City Mod Manager.

Installing Modifications

A Modification on construction for GTA San Andreas.

Vehicles, player and weapons modifications are usually constructed on replacement of already present game objects, because there are limits to number of objects of such kind in game engine, often already filled up by developers, and addition of the new model will require a lot of 'precision' editing in many game files. Therefore, a new car, weapon or clothes will replace the existing one and all installation is reduced to work with IMG archives and little editing of one or two game files in text editor. Always do backup of files touched before any changes occurs.

Installation of larger modifications, such as maps, depends on a method chosen by the developer of mod. Some mods are made as file replacements, mod comes in form of archive which you must unpack to original game`s directory. This simplified installation cost large files to download. Other mods come with special installers (mod installers), which automates work with IMG archives and text-files editing. Both methods usually uncompatible with other mods present, so you must install them over special fresh installation of the original game.


Some gamers consider modifications to spoil the integrity and theme of the game - for example, they don't think a 2005 Lamborghini belongs in a fictitious 1990s world, although you can make your own decisions on these matters.

Most modifications do not alter the status of your game. However, if you install a modification that edits or replaces the mission script file, you will have to begin a new game (except in rare cases), or use a provided savegame created for that specific modification. The game will crash immediately if tried to load an old savegame file.

Modifications that were badly coded (mainly missions) or contain many hi-quality textures and models may results with game performance degradation, jerky framerate and various graphical glitches, especially on old hardware.

GTA IV modding

Many players on the online community of GTA IV on Xbox360 often complain about a player shooting missiles out of his/her weapon. It is a mod made by the creation of an illegal copied disk of GTA IV. This mod will give the player the ability to shoot missiles out of their primary weapon, it lets the player drive a vehicle at any speed. It also makes single player cars (with an array of unofficial paintjobs) and story mode characters to spawn around the modified player. Many people feel angry and annoyed to see a modder in a game, killing them unfairly. Often times a modder would be kicked out of the game or trash-talked to. It is unknown if these players are brought to justice by the xbox live complaint system. Despite the modding being relatively annoying to some, others find modding fun and use it as a way to obtain various abilities or vehicles for their own personal enjoyment or for the players in the current multiplayer game.


You modify your game at your own risk. There is no guarantee that all modifications you download will work, or whether the instructions will be complete. You should make yourself familiar with simple well-known modifications (such as cars) before attempting to install larger and more complex models.

Always read the instructions thoroughly, and always backup files before you edit

Through modding, a player wields two Energy Swords at once, impossible in normal gameplay.

Modding is a way of changing the form and play of a game by manipulating its base coding. This can vary from changing colors of a character, to re-making a map or weapon, such as in Halo 2. Using the mods can significantly alter the processes of a game. As modding is often used for cheating, it is not allowed on Xbox Live and the use of a modded Xbox on Xbox Live will result in a terminated account. However, Halo: Custom Edition, an expansion of Halo PC, was created by Gearbox Software and it is a legal form of modding.

An example of a Meta Tag modding program is Halo Map Tools, or the more supported, advanced Eschaton. Existing modding programs examples are: SparkEdit, or SwordEdit as the Mac equivalent it named, and DotHalo. DotHalo is viewed via winzip for certain computers.


Modding for a Challenge

Some players who get bored of playing the same level over and over again can mod the game and do things like:

  • Turn allies into enemies
  • Change the type of enemy (Grunts to Hunters, Elites to Prophets, etc.)
  • Make new standard weapons (Enforcer Needler, Scarab Gun, Prophet Beam, etc.)
  • Make enemy vehicles appear in different levels
  • Increasing enemy forces

Modding for Cheating

Modding can add weapons, turn weapons that are single-wielded into dual-wielded weapons, such as the Covenant Energy Sword or even Sniper Rifles. Also, mods can make a player jump incredible distances and in some cases, break the game or map barrier. These mods can be used for everyone's enjoyment.

For example, if the assault rifle is modded by the host of the game to shoot tank rounds or sniper bullets, all the players can shoot out the sniper bullets and tank rounds. However, if a joining person has a modded map that shoots out tank rounds, when he shoots, it will appear to him as he's shooting tank rounds, but it has no function - everyone else shoots normally, and everyone else takes normal damage. So in this way, you can't cheat, only do it for everyone's enjoyment. Modifying the game will only work if you are the host. That way people that modify their own maps only mess up their game play.

Modders are legitimate players and do not cheat. They discourage cheaters to be called modders, rather hackers.

Other mods include:

  • Changing a characters' programming
  • Playing as any character (Grunts, Elites, Hunters)
  • Making enemies your allies
  • Auto-Headshots
  • Infinite Ammunition
  • Super-Speed
  • Making undrivable vehicles drivable (e.g. Pelicans, Longswords, Phantoms, etc)
  • Extra Damage Delivered
  • Damage Resistance
  • Cloning yourself
  • The creation of new Weapons
  • The modification of weapons and vehicles (like combining two different vehicles to create a new one with both characteristics) in Halo 2
  • A flying Warthog in Halo: CE
  • The modification of maps
  • The modification of weapon, vehicle, and player spawn points
  • Automatic power weapons, like Sniper rifles and Rocket launchers
  • Creation of energy barriers
  • Creation of flying turrets
  • Changing the physics on a map to make players lightweight or super-dense
  • The introduction of AIs into maps
  • Swapping weapon abilities and characteristics (example: Shotgun ammunition turns into a spray of wraith shots, Plasma pistols shooting Overshield power-ups).

Most of these maps are hard drive maps such as Containment (Level) or Terminal (Level). It is possible to modify the maps on the Game Disk, but it is a very hard process and may break your DVD drive. The easier way is to copy the game to the Xbox hard drive, but you won't be able to play on Xbox LIVE with them.

All of these mods are used in Halo 2 to give the "modder" a slight edge in gameplay. However, he/she can only use a lot of the mods if he/she has host of the game. Often, modders are in a party with a "bridger" or a "stand-byer." The bridger uses a program on the computer which interacts with other players' routers and xboxs to make a modder or anyone else host of the game. This is effective in the process of "leveling-up." This is when gamers join a modder's game to get their level boosted up because the modder is almost unstoppable. Stand-byers use many techniques to freeze other gamers games. This includes: Pressing the "stand-by" button on a modem, and slightly unplugging the Internet cable from their Xbox. When a stand-byer is successful, other gamers either get the dreaded "blue screen" or they get a similar black screen. Everyone but the stand-byer gets this. This allows the stand-byer to run around the map and kill all opponents. This is effective, but illegal, as are all mods.

Any use of these mods is in violation with the Code of Conduct and will get their account banned from all matchmaking games.

Game Crashing

PC modders should be aware of something called an Exception on both Halo PC and Halo 2 for Windows Vista. This occurs when something goes wrong with the mod, or when something done is uncalled for. For example, some mods require a Level restart, or the game will crash, leading to an Exception Error.

In Halo PC, Game crashing usually leads to a Window showing, "Gathering Exception Data" which means the game had crashed through an uncalled for mod, or a physic glitch. While in Halo 2 Vista, the game does not show the window. Instead, it will automatically close, which some claim is an exception.

On Xbox users, Wikipedia stated that there's something called, "Console Crashing" leading to something called, "The Green Screen of Death". If not, the game will freeze.

Bungie takes action

Main article: Halopedia:Bungie With Teeth
The consequence of using mods online

This has become such a widespread problem in the "Matchmaking" system that Bungie was forced to resolve the problem by releasing auto-updates which ban hackers from the system and terminate their accounts. Bungie has banned thousands of players and is working to clean up the rest, earning in the process the moniker 'Banhammer.' Several sites offer a list of cheaters and hackers.

Although there used to be several ways to mod, Xbox Live and Bungie have collaborated to rectify the programming mistakes and prevent the game from being modded as much. They are also reinforcing much stricter punishments for cheaters, such as instant bans and longer suspensions.

Demo Modding

Modding maps in the Demo/Trial version of Halo: Combat Evolved is also possible, although there are a few differences:

The Demo does come with every gametype though. You can access them through modding.

  • Editing: The differences in Demo maps are small, but leave the maps incompatible with other versions of Halo.

The header is scrambled, and the magic used in its monolithic structure has a difference of exactly 0xBAD0000 from the retail version. There are applications which allow for the conversion of retail/CE maps to usable Demo maps, which expand the game to far more than the stock Silent Cartographer and Blood Gulch, but they are considered illegal and are therefore shunned by a portion of the modding community.

Modding for Everyone's Enjoyment

The map Ascension, modded to look like an island.

Most of the time, though, people mod for fun by making the mods on the maps able to be used by everybody in the game. This is what modding was originally intended for: fun and messing around. Often modders make a map with a theme, such as a snowy version of a normal map, a night time version of a normal map, a SWAT type map, or anything you can imagine. Some mods add player models from a Campaign map to a Multiplayer Map, including Heretic Elites, ODSTs etc. Sometimes people make mods just to see what kind of new and innovative things they can do such as "Active Scenery" which allows objects, like Pelican Dropships, to move around the map without AI or anyone controlling it. An example of Bungie made active scenery is the Train on Terminal or the Monitor, 2401 Penitent Tangent, on Backwash.

Modding isn't limited to the Xbox. Halo PC is easily modded, given the right tools, and Halo: Custom Edition even encourages user-created maps. Many popular maps available for Halo: Custom Edition are Yoyorast Island, which is basically a twisty racecourse, Extinction, a very large map set between a large UNSC ship resembling the Pillar of Autumn and a large crashed ship resembling a Covenant ship, and Coldsnap, another very large outdoors map that relies mainly on vehicular combat.

Some also mod to make nice screenshots like those seen at Halouvre, or even to create machinima.

It should be noted, however, that this type of modding can still result in a ban from matchmaking, and is still considered illegal, although Bungie doesn't appear to mind it as long as the modder does not go onto Xbox LIVE.

Halo 3 Mods

Like Halo 2, and Halo: Combat Evolved before it, Halo 3 has already gained some notable[citation needed] mods, provided by community members unaffiliated with Bungie or Microsoft. Though not always used for cheating or providing one player or team an advantage, the use of modded content on Xbox Live in any regard is still considered illegal, and can result in a ban. The biggest change with Halo 3 is the ability to share modded content via File Share making anybody without any modding experience able to play with or view the modded content.

Map mods

Currently, the only way mod maps is to either have a dev kit which requires some files, or to hardmod your 360 and patch some files.[verification needed] Map mods for Halo 3 are like Halo 2, allowing anything to be done to the map that is discovered at the moment, or that you can do in a hex editor or modding program.

Map Variant mods

Mods allow custom map variants to include removed material from the Halo 3 Epsilon build such as Deployable Lookout Towers, Shade turrets and Vehicles like Hornets and Banshees on Narrows and Warthogs on The Pit. Mods also allow objects that can't be forged such as the Elephants on Sandtrap to be duplicated. Additionally, they allow objective melee weapons such as bombs, skulls and flags to be used without playing that gametype. It is also possible to place object out of the map boundaries, but this less impressive because it can also be done using glitches.

Note: Modded content on a map will disappear when a new round in started or when the map variant is saved as a new variant, with a few exceptions.

Gametype mods

Gametype modifications allow changes to certain settings in gametypes. Bungie used enumerated values for Halo 3's Gametypes, so most of the settings are only the ones available from the beginning. There are some settings stored as integer values, for example:

1. Respawn Time

2. Return Time

3. Sudden Death Time

4. Captures per Round

5. Reset Time

Most other values are accessed in a 'list' fashion, which removes much purpose from creating specialized modding tools to edit settings in the main menu. One exception to this is the Primary and Secondary weapons, which have entries enumerated that are not usually accessible to the player. Setting these values produces a blank text in the mainmenu, but a functional weapon ingame. If the current map does not have a selected weapon, the default ( Assault Rifle) is loaded. The list of weapons that can be specified are as follows:

  1. Battle Rifle
  2. Assault Rifle
  3. Plasma Pistol
  4. Spiker
  5. SMG
  6. Carbine
  7. Energy Sword
  8. Magnum
  9. Needler
  10. Plasma Rifle
  11. Rocket Launcher
  12. Shotgun
  13. Sniper Rifle
  14. Brute Shot
  15. Depleted Sword
  16. Beam Rifle
  17. Spartan Laser
  18. No Weapon
  19. Gravity Hammer
  20. Mauler
  21. Flame Thrower
  22. Missile Pod

Gametypes also have the .blf (Blam File Header/Blam Library Format) header, which stores information such as Variant Name, Variant Author, and Variant Description. These fields may be edited to anything, including censored terms, and displayed in the menu. It can become difficult for the original author or any information about the file to be verified locally.

Video & Screenshot mods

With the help of modding, player armor in Film Clip and Recorded Games can be changed to what ever the player wants, even Recon and Bungie Armor. It is possible to share modded map variants and game type variant without being banned through a modding trick: Recorded Games store the game type variant and the map variant information and you can extract these and videos of mods (not modded videos) on File Share will not get you banned.

With modding, it is also possible to replace Screenshots with other pictures such as pornographic material.

Softmods and Hardmods

Contrary to common belief, getting a chip installed in your Xbox is not the only way to have mods. Many popular mods are retrieved through what is called "soft" modding.

  • Soft modding does not require a chip; it is done through a special file and an Action Replay.
  • "Hard" mods are done by acquiring a special chip and installing it on to your Xbox.


Note- There is no "True Source" for modding as it is done at a players demand. However, it may be witnessed in the following games.
