searching for a game, too

[Matthias Söllner <soellner.matthias@t-online.de>]

Hi!
ten years ago I had a game on my iic which I would like to have again,
but I can't remember the
name of this game. Perhaps anyone can help me?

Description of the game:
you had to steer a submarine. This submarine could shoot to the upper
side and to the right side.
the aim of the game was to defence against other submarines, which come
on the screen from the left and from the right. In higher Level, they
shot at you, I think. on the top of screen was a huge boat, where you
could refill your shoots (or your fuel, i don't know)

Thanks in advance
Matthias
