Cerberus pinning, stunning, and shooting St George

The broken hand slammed into St. George’s face. The two remaining fingers grabbed his head in an awkward pinch. He reached up to grab them and the stunners fired up again.
His muscles tensed. This time he felt it in his tongue and teeth and eyes. His eyelids twitched. The finger-claw tightened on his skull and lifted him off the ground. He reached up, tried to shake himself loose, but couldn’t grab hard enough.
He felt the muzzle of the M2 settle against his stomach and a moment later he was punched in the gut a dozen times. At point-blank range the sound itself was a weapon. The barrel rose and the furious rounds battered their way up his chest. Then the impacts tore him free from the damaged fingers and he tumbled away.
St. George staggered back but managed not to fall over. He took in a deep breath to blind the titan with a burst of fire and his chest screamed with pain. A hundred spikes stabbed between his ribs. He coughed out some smoke, a few flickers of flame, and then slumped to his knees.
