The facility reacted. Blast doors closed and more robots were released. Gel that hardened into a substance harder then metal began to spray from nozzles all along the halls whenever Diana drew near. It was meant to stop and freeze escapees in place. The artificial gravity turned off, which didn't bother the robots at all.
New robots began to appear...a overwhelming sea of miniature robots no bigger then a fingernail that packed poisons and electrical shocks. As a last resort, they began pumping out the air until the escapees passed out from lack of oxygen.
