Prowler sends you deep into space, to Ursa Minor Delta-V, where the Peradins are on the attack. Fortunately you have at your disposal a Northall Q15 helicopter-jet hybrid, with advanced weaponry, a zoomable radar and strong shields.
The gameplay involves first-person action, depicted in 3D, with hovercrafts and aircraft among your potential targets. There are various game modes, including air and ground combat of varying intensity levels, as well as five skill levels and full training modes, plus ten set-piece scenarios. The tactical screen must be used to pick out troublesome sectors and launch advance attacks on them.
