GameZone writes, "Sitting down with the Demo on Xbox 360, I played though it once by myself and once with a partner. Between the two, I would say I liked the coop better. My reasoning is that more story was told between the back and forth with Clarke and Carver; at times it even felt ‘buddy copish.’ What confused me about the story is why Isaac cares so much about Ellie in coop mode but doesn’t in single player. During my coop play through, Isaac was yelling for Ellie and concerned for her life; while alone he did none of that. In fact, she never even came up at all."
