Glaring at the man, "Thanks captain obvious.."

His eyes widened at the sight of the invasion force, it was something straight out of the Lord of the Rings. David jumped when the guy shot lasers from his hands. Great, the guy had lasers too. Of course he had lasers. Quickly drawing his two crossbows, the shadow arm drew the sword at his hip. Raising a eyebrow, he didnt tell it to do that. It must react to his emotions, and it seemed to want to defend him at will. Maybe it had a mind of its own?  "Alright, lets take out as many of these guys as we can.

Aiming carefully, he fired the crossbows watching as each bolt hit their mark. Surprised by his new found markmanship. He didnt even think he could do something like this. At least, he think he coudlnt. In the blink of an eye he quickly reloaded both before firing another bolts. One pierced the shoulder of a enemy, and the eye of another. The one who was hit in the shoulder, howled as he charged at him. The Shadow arm moved to defend him. Blocking each strike with a parry. Before thrusting the blade into the neck. 

His eyes widened as a particularly large goblins hit him in the chest with a hammer. Cursing as he was hit into the wall, the shadow arm dropped the sword. Hitting the stone ground with a clank. Gritting between his teeth, he watched as the goblin charge again before the Shadow arm lashed at the goblin clawing it's green face. Seeing it blinded the creature. Drawing his crossbow again, he fired hitting the goblin in the neck. As he stood up he spat some blood on the ground, the Shadow arm gave him a thumbs up before picking up one of the crossbows. 

Seeing one of the goblins charge at Dexter, shooting the crossbow at its back. "Hey Kid, if youre not gonna fight. Get somewhere safe!" he snapped, before firing a few more bolt. Looking at Mackenzie, "Any idea how many are left?"
