GTA IV - Mod Installer + MI Packager

GTA IV, like its predecesors, has a big tolerance for a lot of modding. With the right skills you can modify or add cars, scripts, textures, maps, skins, weapons and more.

For those who posses limited modding capabilities or simply don't want to bother with a lot of manual tasks, Mod Installer was created. With it you can avoid dragging and editing files to get what you want, meaningly a game with plenty of interesting and fun stuff added to it.

It comes with a user-friendly interface which is pretty much self explanatory, making it easy to handle by even the most novice of users. With it you can also download mods automatically instead of having to browse for them online.

Apart from the mod installer, the download provided on this page also offers a packager that allows you to build packs that are compatible with a certain version of the game.
