bolter to the head

"He raised his power fists, strode forward, and pitched in again, his arms slamming back and forth, a blur of mayhem. A bolt pistol was fired at his helm, and for a moment the concussion of the impact blinded him, and his display fizzed and darkened. He struck out on instinct, switched back and forth between power fists and storm bolters, blasted the enemy back, and booted out at grappling claws that sought to tear him down. His helm display steadied, though there was a line of white broken static buzzing across it now, and the Iron Halo rune was greyed out. He felt the suit inject him with an analgesic in the side of his neck, though he did not mind the pain."
