NovaLogic has released the first
playable demo of Comanche 4, their upcoming combat helicopter sim. This "first look" demo will expire by November 16, includes one single-player mission, and require a high-end graphics card, but if you're willing to hover your way around all those requirements and disclaimers, then you can download the demo for a reasonable 42.7 MB. Thanks
Dogfighter.
Update: The demo has been temporarily removed, but a mirror is
online at 3D Gamers.
