As Jace disconnected the enslavement device the second robot got up and jumped towards him. Only for the other one to slam its body into it. The robot he freed pinned the second robot to the wall. Doing just what Jace figured they would do when they were freed. Assist him.
He finished disconnecting the device from the first robot just as he felt heat form on his side. The side of his armor was getting bathed in plasma fire as the special soldiers for the convoy had appeared. Likely drawn in from the battle.
His armor was unable to block the damage since its shields were still down. So he instead felt the heat move through his body. Once again, the attack was not doing any external damage to his armor, but he could feel the heat on that side of his body and it was starting to bother him.
