Remember how replayable Interstellar Rift felt at its best? You might settle into these games easily.
Design starships piece by piece, staff them with crews of individually simulated people, and send them into physics-driven battles where every module can be blown off the hull. Explore a procedurally generated galaxy alone or with friends, test your designs in online PvP, or build without limits in Creative Mode.
