Judging from a quick Lets Play watch, the game is a top down 2D space combat with 3D graphics. You can go down on planets, but it’s a small map and meant mostly to upgrade your ship and repair it. It’s a space game with big focus on combat, but with nothing remotely comparable to NMS, really. Despite the irritating sound effects, I’m actually curious to trying it out sometime in the future.

It had 4 player local co-op, ship to ship combat, and actual meaningful progression and it came out in 1999.
