GTA2: Hacker's Remix
This is a meta mod for Grand Theft Auto 2 (1999) that features a new split screen mode as its main feature. In the current state, all players need Xbox360 controllers (or compatible). The entire mod is designed to work on both Windows and Linux (partially via Wine).
Actually, there are 2 versions in the archive: for Windows and for Linux. Instructions from the author for use are also available inside the archive.
