Fighting off these fuckers wasn't nearly as easy as it had been in the hallway, even with a larger force. For one, the room was open, they could maneuver more easily, and Nick had to be constantly alert for someone sneaking off behind him. This was particularly annoying with the limited vision afforded by his possessing of only a single eye, though his hearing was impeccable and that helped a little. Beyond the Crimson Dynamo's initial intervention, he was also left without any other aid and using his arm might be a bad idea with all the technological equipment. Nick also had to be aware of the fact that their main target would be Tony, who was making himself more vulnerable when he started getting himself intimate with the machinery and removed his helmet. So, really, Nick had his hands full.
His communications with S.H.I.E.L.D. were still veritably dead. He was getting random words, but nothing more, and it wasn't like he could give it any attention when he was trying to dodge bullets and kick ass. The doomsday countdown as a little distracting too, and Nick made the vital mistake of glancing over at it at one point and getting a bullet into his shoulder for his troubles. "Mother fucker!" he roared in pain and then tackled the guy who shot him to the floor. He slammed his head repeatedly until the soldier was unconscious and, sure, there was a lot of blood but the bastard would probably live.
It took approximately eight minutes to take out the remaining three guards and it felt like a lifetime and then there was still the problem of securing them all somewhere in case they regained consciousness because he definitely wasn't going to be stupid enough to just leave them sprawled there where- like in any cheesy action flick- they could jump up at the last moment and attempt to sabotage the whole operation. So Nick dragged them all into a small room across the hall and barricaded the door and all in all this took about twenty minutes and all the while the countdown continued.
He returned to the control room, ten minutes left on the screen, and made his way to hover near Tony. Nick shrugged off his coat and pulled a knife from his boot to begin digging at the bullet in his shoulder with a small hiss of pain. His eyes flickered from his wound to the screens, all these characters in a Cyrillic alphabet that he couldn't understand and he didn't even know how much Tony had done and, worst of all, there was nothing at this point that he could do.
