Hi I have been searching for this game originally created by Amiga..it is an old school 2D vertical scrolling game in the "shoot 'em up" style. You can pilot a helicopter or drive a tank through waves of enemies and bosses. I have tried many different sites looking for a free download or an emulator which would allow unlimited gameplay..including Amiga Forever,RetroGamer and a few others. I could take a chance a buy the game from Amazon and hope I can figure out a way to make the game work on my Asus PC..any thoughts,suggestions would be welcomed in helping a middle aged man relive this great game. Many thanks, Terry.
