"This can't be that big of a bunker," He said, flipping his Mark XI shotgun upside-down so the loading port was facing him as he dual-loaded the weapon, sliding in two slugs at a time before cocking the weapon. He knew these installations would delve further underground, but unless it was a forge world or a hive world, there would be no real need behind it. That still left a good few areas to delve into, however. Hopefully the action would drive out all of the foes so they could take them out without having to do a room-by-room operation. Zeb preferred a squad for that kind of work. 

Bootsteps could be heard across the way upstairs, but it was a door on their level that opened up, drawing their attention. A technician stepped out, or a man who was dressed as a technician. Zeb would have believed it too, had the man not had two diminutive hands jutting from his chest and a horn with a third eye on it protruding from his crown. Despite his fearsome appearance, he looked spooked when he saw Katiyah and Zeb, gurgling a yelp of fear before both Imperials shot him dead. 

"Mutants..." Zeb spat, disgusted. Katiyah looked even more disturbed, scowling. 

Lasers scorched the ground around them, the two slamming into the wall for cover and blindfiring potshots at a 45 degree angle, hoping to score a hit. So far a lot of lasers and ammunition on both sides was being expended for little effort. 

"Grenade!" Katiyah ordered Zeb. 

"I only have Krak grenades!" 

"All the better!" She cried, and finally managed to strike one of the four men, blowing a chunk of his shoulder off. Zeb realized then and there she intended for the second floor of the building to be demoted to the first floor, and that would certain solve a few of their issues. He pulled out the curious looking grenade and primed it, before throwing it right under the ruined stairway. Both Katiyah and Zeb hugged the corner of the rockcrete wall as the explosive detonated, shaking the entirety of the building as that half of the station collapsed with the men along with it.
