DOS Games Discussion

I forget the game of a old. Some fact I remember:
Plattform DOS, I guess early 90's
Genre: 2D Helicopter Game

Description. You played a helicopter in a 2D level, kind of a labirinth. A litte bit like PAC-Man. Every level was one screen big, no side scrolling. Game had arround 20? level, then It restart from level one. In the game you can find rockets, bombs, diamonds and cash. Rockets you can shoot vertically to kill the few existing enemys or more likely to create a shortcut in the "labyrinth". Bombs you just droped down but had the same effect like rockets. After each level you can buy with diamonds and cash you found new helicoters(=lives), rockets or bobms.

Maybe somebody had a guess which game this could be.Thank you!

Are you sure it was a helicopter? It seems strange that a helicopter would have to bother with a labyrinth, breaking walls that could be easily flown over?

Top down view I assume?

yeah it was a helicopter. You can only fly north(up) south(down) west(left) or east(right). No realy change attitude. View was top down, litte bit like pac man
