OpenIV is a robust and comprehensive tool kit that allows prospective modders with the utilities they need to make adjustments to some of the most popular Rockstar games. Rockstar Games is perhaps the most aptly named developers working in the game industry. Every single one of their games exudes swagger, and they've earned a reputation as a company able to put out games with a depth and quality largely unparalleled in the industry. While the Grand Theft Auto series in particular is a franchise so big that every release is an event, practically every game Rockstar puts out is loaded with hundreds of hours of possibilities. For some fans, that's not enough. A number of modding tools have appeared on the market that allow you to change everything from the physics to the character models to the abilities available to players and the physics that define the world. OpenIV is one of the best around, and it's the go to platform you want to own if you're looking to dig into the guts of a Rockstar game and make something original with what's available there. It allows you to manage and archive components of Grand Theft Auto IV, Grand Theft Auto V, and Max Payne 3.
