With the ACA and Hive invasions successfully thwarted, Tranquility's newest colonists are struggling to rebuild. Peace has finally come to humanity's furthest colony, and life is finally starting to return to normal.

The peace was not meant to be.

After receiving a distress call from a distant scouting mission, Lander and the newly formed military find themselves deploying to a dead alien world, where the heart of the Hive lies in wait.

The fate of Tranquility, and Earth itself, hangs in the balance, and for humanity to survive, Lander, Koskov, Gray, and their new companions must stand against the Hive's overwhelming armies and find a way to destroy the most terrifying opponent of all.
