Zero Sum Games' StarDrive is now available on Steam for $26.99. The game is currently 10 percent off until May 3.

StarDrive is a new entry in the "4X space strategy" genre, and has players "starting with a single planet and a small number of space-worthy vessels" before seeking out new worlds to conquer and colonies to build and defend. The game features real-time gameplay, eight playable alien races and customizable fleet formations.

StarDrive's publisher is Iceberg Interactive, which published another popular 4X game, Endless Space.
