Echelon PC comments

Echelon is a futuristic flight combat game
that puts you in white-knuckle combat over lush alien landscapes and
towering cities as a member of an elite fighting force facing a revolution
on a colonial outpost.

Featuring branching campaigns, a broad range of player craft, and three
unique flight models, Echelon's intuitive controls allow you to customize
your experience to that of a pure action game, or one with more flight sim
elements. Support is provided for keyboard, keyboard/mouse, or joystick.
