The internal scanners on the command deck displayed several sections on the map blacked out, the damaged sections. Near them and moving steadily towards the center and command deck were several xeno-lifesigns. The marines near the entrance had also heard the situation, and upon Sergeant Ramirez's orders, had departed there and were making their way towards the command deck. It seemed like they would make it before the xenos.
On the map were several places where potential ambushes or killzones could be set up. The command deck itself was fairly heavily fortified, with double blast doors at the entrance. From there, the corridors branch out to the 4 main sections, each roughly a quarter of the dome-shaped structure. Internal bulkheads were set up at every major intersections, as well as every room. It was designed to be able to operate in vacuum conditions, after all, so all sections could be sealed off.
"We already tried sealing them in where they came aboard, but that quarter is almost completely destroyed, and the circuits must be damaged too badly. We don't have any control over systems in that area."
Said the head operator, while switching between couple of monitors and trying to do something to slow the zerg.
