Eryx stayed outside when they entered the building, these rebels couldn't live to be in the way of this operation. His helmet had triggered, he was adjusting to trajectory and firing paths of the rounds as well as enemy movement as his module had kicked in.

Bullets landed around him as he aimed the handgun up, firing controlled shots at the enemy position to punch through the material with inference on the location of enemy vitals on the other side.
