This a slightly spruced up version of the free The Ur-Quan Masters. However, far as I understand it, it is provided by the original makers of Star Control II (that have since lost the IP).

Description from Steam:

Experience the award-winning space saga. Travel to hyperspace, discover alien worlds, and meet an eclectic cast of characters. Find out what happened after the Ur-Quan invasion. And if the war still rages, fight for Earth and the Alliance of Free Stars!
