Nintendo DS

Overview

A game created by Square Enix featuring two main characters Ibuki and Yui who live atop the back of a giant creature known as Gigant. Square Enix had a special teaser site with a countdown to build anticipation for the reveal of this title. The game was also shown in Shonen Jump but little is known about the gameplay still. Obvious similarities have been drawn to Shadow of the Colossus although that is certainly a fair and flattering comparison.

Gameplay

As Ibuki and Yui, you must defend Gigant against attackers or comparable proportions. This means you'll be fighting colossal creatures and the games first trailer demonstrates that such a daunting task will be undertaken by performing actions like running up the creatures arm and attacking it's head.
