Before the announcement of Shadow of the Colossus, a sequel to Ico was in the works. The game went under the name of Nico (clever since ni means two in Japanese) and this trailer shows a little of what the game had to offer. It starts out with a bunch of people riding horses and ends with a flash of a colossus flight. Except there’s one surprise that Ico fans are bound to get a kick out of. After watching this it’s clear that Nico was the ground work for Shadow of the Colossus.
