MX vs. ATV is an American racing video game franchise developed by Rainbow Studios and published by THQ Nordic that focuses on off-road racing, as a crossover between THQ's MX trilogy and Sony's ATV Offroad Fury series. Early games in the series, starting with MX vs. ATV Unleashed, were published by THQ prior to its bankruptcy and liquidation in 2013. As the name suggests, the series' main focus is racing with motocross bikes and all-terrain vehicles, although other vehicles such as dune buggies and sport trucks were also featured in the games. Players can also fly airplanes and helicopters in some of the games.
