Cerberus Mk 2 closing a gate on Exes

The exoskeleton reached out and grabbed the gate with gore-soaked fingers. Cesar swung it toward himself and then pushed it shut. Two or three exes pressed against it, but the suit overpowered them with minimal effort and power drain. One last dead person, a man with blood-streaked sideburns, tried to stumble through the shrinking opening. The battlesuit’s servos whined once and crushed the man’s arms between the gate and the latch.
Cesar shifted his feet. He set two steel toes against the base of the gate and locked the joints. “I got it,” he called back.
The targeting system lit up something in the rear cameras. The kind-of-Madelyn. It was inside the gate.
