I remember playing the crap out of it. It was a space game where you colonized asteroids and mined the ore to purchase defense systems against competing companies. I think the company you worked for was tetra corp, or something like that.
It had a bunch of cool little features like sending spies to other planets to sabotage defenses and different missle that would do various damage.
The only thing that was bad was it wasn't goal oriented where you completed a task then had another. It just keep going until someone attacked you or you attacked them.
Does anyone remember it or if there is something similar(a sequel maybe)??
