With the Mechwarrior games being my only Simulation experience, I bought this one mainly for the cool pictures on the box. For once, they did justice to the frosty disc within. Playing Lt. Casey, you fly missions against a strange invading foe, intent on extinguishing all life they find. Spanning three discs, I lost count of the missions I flew. I was so involved, I actually jumped when I was blown up! I've never played a game that left me shaking afterwards...this one grabs you by the neck, wrings you out, and leaves you exhausted but wanting more. Keeping it from 5 stars is a small glitch that makes the mouse pointer travel across the screen by itself, making menu items difficult to choose at times. A small flaw indeed, but an annoying one.
