- This article is about modifying game files. For the garages that modify vehicles in Grand Theft Auto: San Andreas, see Mod Garages.
from GTA V, in GTA San Andreas.
A popular car to mod, particularly in GTA V, is the police cars.
Car modifications that put real-life cars into the game (for example, McLaren P1
) are among the most common and popular modifications throughout the entire GTA series.
A modification (known as a mod for short) is an alteration to a Grand Theft Auto game. Grand Theft Auto modifications are created by fans after the game's release, and are normally 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 and, recently, mobile (iOS and Android) versions of Grand Theft Auto games, although the latter two require jailbreaking (iOS) or root access/APK editing for certain mods (Android). There are methods of modifying console versions, but these are complex and usually break the license agreement of the game and the game console.
Modifications are applicable for:
- Grand Theft Auto 1 (PC)
- Grand Theft Auto: London 1969 (PC)
- Grand Theft Auto: London 1961 (PC)
- Grand Theft Auto 2 (PC)
- Grand Theft Auto III (PC, iOS, Android)
- Grand Theft Auto: Vice City (PC, iOS, Android)
- Grand Theft Auto: San Andreas (PC, iOS, Android)
- Grand Theft Auto IV and expansions (PC, PS3, Xbox 360)
- Grand Theft Auto V (PC, PS3, PS4, Xbox 360, Xbox One)
Different Types of Modifications
Modifications in special websites usually are distributed on several categories, depending on the aspect of the game that they change:
An example of a map mod. Shown here is the Chiliad Chalet, which adds a chalet styled club in the top of Mount Chiliad
Adds 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 include:
- Odie's Stunt Park (GTA III)
- Pleasure Island (GTA VC)
- Liberty City (GTA VC)
- San Andreas (GTA VC)
- WTC (GTA SA)
- Chiliad Chalet (GTA SA)
- Verdant Meadows Marina (GTA SA)
- Countryside Mountains (GTA IV)
- Ghost Peak Mountain (GTA IV)
- San Andreas (GTA IV)
Alters or replaces the mission script (main.scm in all of the GTA III Era games) of the 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, including but not limited to:
Some patches or fixes attempt to restore hidden/removed features in the game, such as the Ghost Town in GTA III and scenes for adults in GTA San Andreas.
An example of a player/ped mod. Shown here is the mod that lets player play as pedestrians rather than Franklin
without the use of Rockstar Editor.
- Player / Pedestrians
Basically it changes the model of the protagonist or other NPCs in the game, adds new clothing items, or even adds new sound/animation data. These began after the release of GTA III, which contained an appreciable alternate skin for Claude. Examples include:
Changes vehicles in the game. It can range from simply replacing vehicle colors or tweaking the performance stats to adding new vehicles, replacing them with a hi-poly modeled and textured version, or even replacing them with a brand new vehicle altogether. This is the most common type of mod in the GTA series. Examples are:
As a side note, the majority of vehicle mods are real-life vehicles, usually ripped from other games with vehicles (e.g. racing games, although other Grand Theft Auto games are also applicable).
An example of a weapon mod. Shown here is a scissor melee weapon on GTA Vice City.
Alters weapon models and data, like accuracy or rate of fire, and shot sound. Weapon models are usually taken from other action games (e.g. Half-Life, Halo, etc.), although other Grand Theft Auto games are also applicable.
- Total Conversions (TC)
Total Conversions encompass many of these features at once. TCs generally change everything in that GTA game, including the map, vehicles, pedestrians, player, and missions. A few TC mods been made and completed (e.g. GTA Long Night, GTA Gostown, GTA United, a zombified Vice City total conversion mod for GTA Vice City), and there have been many more planned that have never reached a release.
Sometimes known as script mods, gameplay mods change the way players play the game. These mod usually have their own custom script but don't interfere with the main.scm script file. Script mods are also sometimes known as "for fun" mods because they are often used to spawn so-called "myths" in certain places, giving players special weapons, the ability to control the weather, etc. 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. Sometimes these mods are just simple, such as modifying the game's clock to last up to 24 hours.
Another popular type of mod is fixing the physics. Originally, the physics engine was unrealistic. However, because of CLEO mods, some gamers have been able to change the physics engine by importing the RAGE engine (Rockstar Advanced Game Engine) into GTA San Andreas and GTA Vice City. A popular mod is the "GTA San Andreas Rag-doll" mod. In GTA III, this is much harder to do since limbs come off in the PC version.
Another popular type of mod is cosmetic replacement. For example, there are mods that replace fictional brands into real ones (e.g. Burger Shot changing into Burger King) or replace vehicles with their real-life counterparts (e.g. the Super GT from GTA IV changing into an Aston Martin DB9). Sometimes, these even replace district names to match their real ones. An example is the GTA San Andreas real mod.
Texture mods qualify as these (e.g. adding real-life badges onto the car being modified).
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 the game files.
Example of a trainer mod. This one is the Enhanced Native Trainer mod being used in GTA V.
Trainers are programs that run alongside the game and manipulate 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.
Example of a multiplayer mod. The picture shows a gameplay shot of Multi Theft Auto, a multiplayer mod for GTA San Andreas.
As all PC versions of the GTA III Era games lack multiplayer capabilities, gamer communities started creating 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 servers, but usually are versions of FPS-like deathmatch/CTF or rally/street races. Examples include:
Example of an enhancer mod, which adds reflection, replace the sky textures with HD ones and improve the vegetation textures. The picture shows the effect.
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 enhancers also apply modern shader post-processing effects to game graphics. Notable enhancers include:
Some things, like car colors and handling, weapons characteristics, and ped relations, can be changed easily because all the data necessary stay 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) is more difficult, 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 ZModeler are also used. Textures are less complex, but still tricky. Textures normally should be the same size as their originals, because bigger ones may cause the game to lag depending on FPS, as those appear in higher resolution. Also, some textures may contain an alpha texture.
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. Recently, however, a tool called Design Your Own Mission (DYOM), specifically for San Andreas, makes making missions less complex, but these are usually simple.
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 vehicle in a few hours. Many modifications take months.
- Vice City Mod Manager
Vice City Mod Manager (VCMM) is a tool for modifying objects in GTA 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
San Andreas Mod Manager (SAMM) is a mod manager for GTA San Andreas. It does the same thing as Vice City Mod Manager.
A Modification on construction for GTA San Andreas.
Vehicle, player, and weapon mods 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 vehicle, weapon, or character model 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 change 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, where the mod comes in the form of an archive which you must unpack to the original game's directory. This simplified installation costs large files to download. Other mods come with special installers ("mod installers"), which automate work with IMG archives and text-files editing. Both methods are usually incompatible with other mods present, so you must install them over special fresh installation of the original game.
One of the most popular vehicle mod in GTA San Andreas, the Stinger
. The Stinger
was one of the most popular sports cars in the 3D Universe
GTA Series that were absent in GTA San Andreas. With some modifications, the Stinger
can be inserted into GTA San Andreas and driven like a normal car. Shown model is the GTA Vice City version.
- Some gamers consider modifications to spoil the integrity and theme of the game — for example:
- 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 you try to load an old savegame file.
- Modifications that were badly coded (mainly missions) or contain many hi-quality textures and models may result with game performance degradation, jerky framerate, and various graphical glitches, especially on old hardware.
- Some visual modifications can make the game show even more brutality, violence and even NSFW content, which is not very recommended for young players.
- Also, most modifications are made for PC, while the rest are made for iOS/Android. Attempting to install the mods cross-platform (iOS/Android on PC, and vice versa) may result in either graphical oddities or even game crashes.
- Usually, when installing new vehicle/weapon mods, the game will still display the original vehicles' or weapons' names. (For example: Ferrari Enzo still had the Cheetah as its in-game name) To correct this, modify the GXT file of the language you are using.
- Except for the iOS/Android version of GTA III, the iOS/Android versions of GTA III Era games no longer use TXD files, instead putting all textures in a gta3.txt file, along with extra files corresponding to a certain graphics processor (pvr for PowerVR, etc.).
Modding on GTA IV
As with the previous GTA games, modding continues to be prominent on Grand Theft Auto IV.
While most players mod the PC version of Grand Theft Auto IV, many players also mod the Xbox 360 and PS3 versions of GTA IV. One of the most predominantly used mods on the console versions of GTA IV will give the player the ability to shoot rockets out of guns other than rocket launchers. Many modders will also use a "speedup" mod that allows them to drive vehicles at incredibly fast speeds, sometimes fast enough to make the vehicle start flying. Modders also spawn cars that are not available in multiplayer with an array of unofficial paintjobs. Modders will also spawn story mode characters as bodyguards. Many people feel angry and annoyed to see a modder in a Free Mode game, usually because they are killing the other players with their modified weapons. Often times a modder will be kicked out of the game or trash-talked to. Despite 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.
Modding on GTA V
Modding in GTA V starts in the same time as the release, which was on April 2015. In this image, a player and vehicle mods were seen.
As with the previous GTA games, modding continues to be prominent on Grand Theft Auto V. However, Rockstar originally banned modifications, even in Single Player, due to the presence of Grand Theft Auto Online. Each update deletes some data modifications installed and disables script mods usability, meaning the player will have to install them back in, as long as they have been changed to be compatible with the new version.
GXT files are now known as GXT2.
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 vehicles) before attempting to install larger and more complex models.
It is also recommended to test one mod at a time before proceeding into another, because some mods can also introduce new bugs, glitches, or even crash the game. After you think it is fine to use, then you can start proceeding into anothers.
Remember also to check the files for any harmful programs. Some mods can also contain computer-breaking files or even viruses, such as the infamous Angry Planes and NoClip mod for GTA V that was found out to contain malware, and contain a keylogger to steal your accounts' passwords.
Always read the instructions thoroughly, and always backup files before you edit.
Should you bring any modifications to GTA Online and your account will be immediately locked with a ban.
