From boiling hot industrial factories to the decaying water maintenance zone afflicted by constant acid rainfall - Tertium Hive is a hard and unforgiving place even at the best of times.

You must team up with 3 other renegades. A Veteran, a zealot, and a large ogryn.

In the grim darkness of the far future…

There is only war.
