Cerberus and Peasy exchanging punches

The cannons roared again. Between the walls of the Mount and the nearby office buildings the sound itself was a weapon. The gate guards winced. Another two trucks vanished in clouds of shrapnel, and Seventeens screamed. More exes vanished in splashes of dark blood and rotted meat. Rodney staggered back as a hundred rounds punched through him like a swarm of high-caliber hornets.
The counters dropped into double digits, single, and the cannons clanged open. The silence was deafening.
Rodney stood up and coils of meat unspooled from his stomach. The intestines spilled over the ground and he reached down to tear them loose. “Someone hasn’t been paying attention,” he laughed. “Body shots don’t do nothing and we don’t get tired. Twenty minutes with your boy toy and I’m still fresh and ready to go.”
He lunged at the armor and they met eye to eye. His massive fists clanged against the armored helmet. He drove his knee up into the battlesuit’s crotch and jerked it a foot off the ground.
Cerberus brought her own knee up and heard his pelvis crack. She shoved him away and slammed her gauntlet into his ragged face.
He grabbed a gun barrel in his hands and twisted. Metal shrieked as he tore the cannon away from the battlesuit’s arm.
Inside the helmet a handful of warnings flashed. Two subsystems shut down on their own to prevent shorts.
