Comanche 4

Althought quite old I will never stop liking that game.... you basically flew a comanche helicopter and blew stuff up .... what more could you want? but the graphics would be classed as bad nowadays... thought the explosions still look pretty nice... if you dont have this game or played why not just go and grab the demo here:
