Space Cops!
From D&D Wiki
This system uses the Tiny Frontiers setting
Background
Space has been colonized, but it's full of space criminals. Enter UCOP. The United Coalition of Planets. A conglomeration of all the galactically recognized major players that sends their best of the best to help sort out the galaxy's problems.
This was a one shot game that I rather enjoyed and wouldn't mind picking up later.
