[PC][late 90's / early 00's] Top down Space shooter

Got the game before 2004, on a disc probably with other games on it as well. It was top down, arcade style play (don't remember having to use the mouse, space shooter. I cannot remember any plot line at all, I do seem to remember being able to gather or mine minerals from asteroids, sell things at stations and destroy other ships. It looked similar to continuum (subspace) graphics wise but it was single player. It's not escape velocity, transcendence, space rangers or solar winds although it does appear very similar to transcendence just a bit better graphics.

I seem to remember being able to upgrade multiple aspects of the ship, cargo hold perhaps, shields / weaponry definitely, there were other NPC spaceships around - some hostile some not.
