Marcus Stephenson better known as THQ Tank is on his way out. He is leaving due to having a "new opportunity" he's received. His replacement hasn't been named yet but in the meantime "THQBasol" will be taking over for Tank on an interim basis with WWEGames. "THQ_Shamownage" will be taking over on the UFC Undisputed front.
