Captain Freedom fighting with a broken rib

Freedom looked at the approaching wave of undead. The cracked ribs flared as he turned. His legs flexed and he hurled himself away from the crater.
As he landed a dozen exes reached the edge where he’d been. They tumbled in. The first few hit the glassy floor with the loud cracks of breaking jaws and noses. The dead made no attempt to break their fall. Some of them crawled away before the second wave fell on top of them, but not many. In a minute the pit had become a mass of undead limbs and chattering teeth.
Three other exes reached Freedom. He lashed out with his massive fists, breaking teeth and skulls and glad for his Kevlar gloves.
