Time was running out, and the Imperial forces were completely outnumbered. The squads on the hulk had suffered heavy casualties, while as many as 35,000 Genestealers still lay in cryogenic slumber. There was one last tactic open to the Blood Angels: they could flood the cryogenic chambers with a deadly toxic gas.
The information retrieved by the C.A.T. had identified a cluster of ducts in a room more than four sectors away from the Space Marine beachhead. These ducts cycled air round the cryogenic chambers, and were the most efficient method of distributing the toxic gas. The remaining Space Marines advanced through extremely light opposition towards the target area.
As they moved it became obvious that a second wave of Genestealers, much larger than the first, was beginning to emerge from cryogenic slumber. Surveillance from the Intolerance assessed this second force as having a strength of 4,000, while the remaining 30,000 or more Genestealers were also commencing their recovery cycles.
By the time they were within two sectors of the target room, the Space Marine phalanx was down to only 22 Terminators. The area around the target room was, apparently by coincidence, occupied by a relatively strong enemy force. A frontal assault would be costly and time consuming. Success seemed to be slipping through the Blood Angels' grasp.
The order was issued to sacrifice almost half of the remaining Space Marines in a decoy action. If they could draw enough of the enemy away, the room could easily be taken, and, if they could keep going long enough, they would buy precious seconds for the cryogenic attack.
The Space Marines are attempting to reach a cryogenics chamber just to the south of the sectors shown here, both to destroy the several thousand Genestealers inside it before they wake up, and to draw off Stealers from the real target of the assault.
Squad Lysand and Squad Parin are attempting to get through this sector alive.
The mission is a success if five Space Marines leave the map via the red exit point.
The Space Marines move first.
Three blips are already present. Two more blips will arrive each turn.
