Sin turned as a human Spartan began fighting the Loyalist Covenant forces as well. He gave a nod to the Spartan and continued firing is Assault cannon at the other Covenant. A rather brave or stupid Skirmisher got close to the Hunter and sent a plasma round into his exposed "stomach." Sin gave a growl and charged the offender, slashing it's neck nearly all the way off with the blade on his shield. He stepped on the Skirmisher's corpse as he moved forward and blasted another Brute, causing some of the Grunts he was commanding to flee.
