Revvin' up your engine, Listen to her howlin' roar, Metal under tension, Beggin' you to touch and go, Highway to the danger zone, Ride into the danger zone... Ok I'll stop now, but seriously that's the tribute behind this Shoot em up, it's Top-Gun, a developer tribute to the film. In this game you'll be fighting waves of alien enemies as the world is under attack from an alien assault, but the only ones brave enough or stupid enough to take on this threat is America's best pilots, the top guns! Danger Zone, which is another reference is a vertical top down scrolling shooter from archvizer that sways more towards the avoiding of enemies and bullets than actually fighting in a shoot em up genre.
