Despite heavy opposition, Squads Pesaro and Limbus had achieved their objective, holding off the Genestealers until the alien data had been transmitted to the Blood Angels mother ship. Initial analysis of the data streams showed that the ship was not the floating hulk the Space Marines had supposed it to be but was in fact being directed by an external source based on the planet of Grazarch XXIV in the nearby Altron star system.
Further analysis revealed that the hulk had drifted through the Altron system some time in the recent past and had dropped a number of landing pods onto the planet. The only possible conclusion was that the small Imperial mining colony on Grazarch had been overrun and that someone or something on the planet was directing the hulk. All attempts to establish communications with Grazarch failed, but an Astropath on Formund informed the Blood Angels that all contact with the mining colony had been lost for three years.
Captain Lorenzo knew that he had to deal with this threat. The alien signal emanating from Grazarch could control more than just the hulk's movements - it might be able to activate the ship's weapons systems, force the hulk back into the warp, or even trigger a self-destruct sequence. The only way that the threat could be neutralised was to sever the communication stream before the alien intelligence could prevent them breaking its control.
While the bulk of the Terminator force continued to clear the hulk of Genestealers, Squads Myran and Catullus were despatched to destroy the alien receiver.
The Space Marines must get to the communications console and cut off the alien communication link.
Squads Myran and Catullus must sever the outside control link to the hulk.
A Space Marine must get to the computer console and spend 4 action points to terminate the link.
The Space Marines move first.
