Slitherine and developer The Artistocrats’ previously-announced “Raising Hell” expansion for Starship Troopers: Terran Command has busted out of development, and is now available. The expansion includes seven detailed missions set on the fiery volcanic planet of Gehenna, as well as a roster of new units and mechanics.

Gehenna, the hellscape central to Starship Troopers: Terran Command – Raising Hell, is prime real estate. A massive stream of space freighters feed from Vilon Station, located high above the lava and flames of Gehenna’s surface. A nexus in mining and trade, the fiery planet is critical to the Federation’s war efforts. With Arachnid infestation rising sharply, the contracted mercenary groups are no longer sufficient for protection. The Mobile Infantry is once again called upon to deploy.

Players will take charge of some fresh Mobile Infantry forces, including the new Powered Suit Incinerators and Powered Suit Officers, and gain access to Mercenary units, from tough mini-gun equipped Shredder Mercs to Engineering Bipeds with their powerful drills. You’re not the only one with new toys, however. The Arachnids have evolved in the harsh environment to spawn their own new units. These include nimble Stingers shooting superheated projectiles, airborne Pyroflies, and the monstrous Immolator, which can explosively burst when mortally wounded.

Currently, Starship Troopers: Terran Command is available for PC via Steam.
