The Sentinels: Underground

The Sentinel Force has protected the three remaining Marble Cities on the planet Centauris for centuries. They have fought against the vicious creatures known as the Lontanus for as long as anyone can remember. Now, they seek any opportunity to end the war, once and for all. This has never been harder, however, as a leader of the Lontanus, known as a Dominant, challenges them. Her fury will be known across the Marble Cities for generations, but so will the tactics and determination of the Sentinels.
