# Open76: reimplementing Interstate '76 in Unity

> Open76 is a Unity reimplementation of Interstate '76. It parses and renders level contents, including cars, and can run the mission stack machines. Driving and camera modes work. The README says the car simulation, including the engine and gearbox, still needs work.
