When the Invictors were dispatched to investigate a mysterious Space Hulk that had recently emerged into realspace from the warp, they soon encountered and ancient and foreboding enemy, in the form of vile Genestealers - harbingers of a Tyranid Hive Fleet.

History
When a mysterious and ancient Space Hulk emerged into the materium from the warp, the opportunity to explore and discover potential STC or ancient archaeotech was too good an opportunity to pass up. The Invictors of Mars dispatched their finest warriors from both the elite 1st and 2nd Divisions. Both elements boarded medium-sized Space Hulk and began their systematic search of the various derelict vessels that made up the bulk of the Space Hulk, for any lost or potentially vital technology that could be reclaimed on behalf of the Omnissiah. Unknown to the exploring Astartes, within the massive confines of the derelict Space Hulk, lying dormant deep within, were hundreds or thousands of deadly genestealers, who could wake at any second to devour the intruding Space Marines.

With the Chapter's speciality being the best solution of survival for the teams that boarded the hulk, they slowly moved around the ship, strategically placing bombs along the way. When they reached the main reactor, they fortified this area from any genestealers from entering. They then placed a belt of krak grenades inside it. The Invictors had quickly realised upon entering the Space Hulk, that the risk in battle-brothers' lives were not worth the potential gain, and instead opted to destroy the massive derelict, destroying any potential xenos and to prevent any technology from falling into the wrong hands. The Invictors withdrew from the Space Hulk, taking only minimum casualties, as their timed explosives detonated after they had already boarded their awaiting vessels, destroying the Space Hulk in a spectacular fashion.
