Novel Cont. Numero Quatro

Hello everyone, I'm back, and I've written a bunch for my novel, so here it is.

    Damian looked up sharply.  He had to move, or he'd be caught between the blast and LARCO's private military forces.  Shrugging the satchel back over his shoulder, he grabbed the disk and ran.  The tunnel walls blurred into grey streaks beside him as he sprinted.  Gasping, he reached the elevator.  His hand grasped the lever, but it wouldn't budge.  He backed away slowly as the doors began to open.
    The first soldier took a step from the opening.  He was a light infantryman, armed with a submachine gun.  He raised it to his shoulder to fire, but he was a split second too slow. His helmet shattered as Damian's first shot ripped through it.  His body hit the floor mere moments before those of his companions.  Damian stepped over the corpses and into the elevator.
    There was an SMG on the floor.  Damian picked it up and inspected it.  It was just a standard issue LARCO SF90.  It was already primed, and he shouldered it.  The elevator reached the top of the shaft, and the doors slid open.  Peeking around the corner, he saw nothing.  He took a tentative step out, and that was his mistake.
    He hadn't checked the other side.  A soldier tackled him to the floor, stabbing down with a serrated combat knife.  Damian raised the gun to block, and sparks flew at the contact.  He batted away the second stab, and punched the man in the face.  The soldier rolled, dragging Damian over as well.  Damian kicked underneath him, breaking free of the grip, and stumbled to his feet.  He'd dropped his gun, and the soldier was now standing in front of it.  The soldier grinned, stepping forward and thrusting at Damian's chest.  Damian reacted swiftly, redirecting the lunge and placing one hand under the man's hand, which was clenching the blade, and one on the side of the blade itself.  He twisted his hands and the man's wrist shattered.  Yelling, the assailant doubled over in agony, then looked up.  Damian's boot caught him in the temple, and he crumpled.  Damian reclaimed his gun and ran down the hall.
    There were doors, everywhere, and about a million hallways.  Damian looked about, frantically searching for the right one.  They all looked the same.  There was a deep rumbling, and he took off at a fast jog.  The bomb would go off at any minute, and he was still in the building.
