I must say though...titan mode is terrible. It totally adds a deadlock stalemate to many game types ( greed ). Where the titan players will just go on defense since they can't pick up the skulls, and therefore neither team can successfully score. Although I won't deny that titan mode looks cool, its just a mutator that really doesn't do anything except add stalemates to games, and make dominant players even more dominant hence increasing the slippery slope.
