GTA San Andreas mods: how to install them without breaking the game

The official position is the Mod Guidelines page on Rockstar's site, last updated on September 10, 2026. In short: mods are generally acceptable, but Rockstar doesn't endorse or sponsor third-party projects and can take down any mod. Prohibited:

• altering the official story, missions and characters as if it were a Rockstar continuation;
• moving content from one Rockstar game to another;
• porting games to platforms where they weren't officially released;
• making multiplayer mods outside the official licensed Creator Platform;
• making money from mods (monetization only through the Creator Platform) and using the voices of Rockstar's actors.

For San Andreas this means graphics upgrades, new cars, scripts and fixes for your own single-player game are normal community practice. "Remakes" on other engines and ports to other devices are already pushing the rules.

Almost every well-known San Andreas mod was made for the original PC version. You can't buy it now: the original's Steam page says the game is unavailable. Mods are installed by people who already own it, from a disc, an old Steam purchase or the Rockstar launcher (owners of the PC Definitive Edition were given the original until June 30, 2022).

The Definitive Edition is built on Unreal Engine 4, so old mod files don't fit it. The community makes separate tools for the remaster, such as CLEO Redux, which runs scripts in the "3D era" GTA games. The choice of mods for the remaster is much smaller.

CLEO. A library plugin that lets you run third-party scripts with the .cs extension. The CLEO developers themselves stress that scripts are written by users and aren't supported by the library's authors. CLEO runs through ASI Loader and ships with it.

ASI Loader. A small file that loads .asi plugins into the game. CLEO builds come with two options: Silent's ASI Loader or Ultimate ASI Loader (by ThirteenAG). Installing it replaces the game's original vorbisFile.dll file, so the developers advise keeping a copy beforehand.

Mod Loader. A plugin for GTA III, Vice City and San Andreas: mods go into a separate modloader folder, and removing a mod just means deleting its folder. According to its author, the game's original files aren't changed; everything is swapped in at launch. It's the simplest way to avoid "killing" the game with a bad mod.

These three tools are the foundation: most car, graphics and script mods are designed around them. Download them only from the projects' official pages, not from random "bundles".

1. Copy the whole game folder somewhere else. Restoring it is easier than reinstalling.
2. Back up your saves. In the original they're in Documents, in the GTA San Andreas User Files folder. Before mods that change missions or scripts, start a separate slot.
3. Install Mod Loader first, then put mods in its folder instead of replacing files by hand.
4. Add one mod at a time and launch the game after each. That way you see right away what broke the launch.
5. Don't run .exe "installers" from unknown sites, even if they promise "automatic installation". A proper mod is files and instructions, not a program with administrator rights.
6. Scan archives with antivirus and read the comments under the mod: does it work with your version of the game?

Cars. The most common search: mods replace the stock vehicles with real-world models. Usually these are model and texture files you drop into the Mod Loader folder. The more detailed the model, the harder it hits the old game.

Graphics. New textures, lighting, draw distance. Heavy graphics packs often conflict with each other, so the one-mod-at-a-time rule matters especially here.

Remakes on new engines. Fan projects like "San Andreas in the GTA 5 engine" or on Unreal Engine 5 move content between games, which the Mod Guidelines explicitly forbid. Rockstar can take such projects down at any time.

Multiplayer. SA-MP, open.mp and MTA:SA are fan multiplayer mods for the original PC version. Rockstar didn't make them; under the current rules, multiplayer mods are only allowed through the Creator Platform.

Officially, mobile versions don't support mods. "Android mods" are almost always a modified APK or OBB file that someone repackaged. The risks are direct: such files can contain malware, and the game stops updating from the store once installed. The legal official mobile versions and their prices are on the GTA San Andreas on mobile page.

If you want money, weapons or a jetpack, you don't need a mod: San Andreas has around a hundred built-in cheats that work in both the original and the remaster. The table is on the GTA San Andreas cheats page.
