Tomahawk was not here to kill humans, he was here to save mutants. The sniper rifle would be fun, but he needed to conserve the ammo for the generator. That was what the shotgun was for. He slipped the straps from his side arm to the rifle to keep it in place as he took off from the most recent carnage. 

Still covered in blood, he made his way to the hole in the wall made by the cannon fire And spotted two guards using the covered exposure to open fire. Squatting down, he snapped up into a leap beyond a human scope and fired off a round right into the helmet of the one of the left. Their armor would protet them, but all he needed was just for the knockout rather than a headshot. Not to waste the momentum of the surprise, he grabbed the wall lip with his left hand and swung with the right to take the gripped gun and bring it in sideways on the kneecap with a wet snap of satisfaction as the guard went down enough for him to hook the body with the barrel to pull the human out of the hole to fall to the ground.

Securing himself in where the guards had positioned themselves, he took a moment to pop off the guards shattered helmet and remove his ear piece to gain tactical information on the enemy, it was risky having a device in each ear, so he had a choice to make. Wait, no he didnt, he cant make a better use of this, but there is someone who can.

"Forge, can you rig something from Enemy headsets like a high volume screech or something to stun them? I have one to bring you as a sample if needed."

From up on the catwalks where the hole in the wall was made. Tomahawk continued to work his way further into the prison to the Primary generator, from here he would have to cut even deeper into the center for the backup generator.But for now he took a nook in the rafters above the catwalk and sighted up his shot.
