Grand Theft Auto: Liberty City a total conversion modification for Grand Theft Auto: Vice City. Ever since GTA: Vice City was released, ongoing work has been done to bring the world of GTA III into the new game engine. This allows you to play with features that are not present in GTA III (like motorcycles, helicopters, ability to kill vehicle occupants, and tire bursts). Although there are many similarities between the two game engines, there are enough complex differences that people are still working on the project to this day. Helicopters, Planes, Bikes, all the enhancements you found in Vice City, inside the GTA III world. Ever wanted to attack Marco's Bistro from an Apache helicopter? This is the mod for you! Now you can fly, die and ultimately have a whole new barrel of fun in the Grand Theft Auto III world!
