DOS Games Discussion

Can anyone help me find this old space game. I played it in the early 90's.

You fly a craft styled on the asteriod craft around various obstacles whilst being fired at by various ground stations. You can only fire five shots at a time until they hit something then you can fire again. THe shots move slow by todays standards. You can also switch to a single missle or bomb. The manovering is very stricky through some very tight corners and horizintal paths.
The game is very slow and controlled requiring concentration as opposed to shooting em up.
Any ideas?

I believe the game your describing is OIDS I looked for that game actually about two years ago and found it. It wasn't very hard to find but that sounds exactly like OIDS.
