sentences:  A video released in the weeks before E3 2009 showed early footage of the game with its working title, "Project Trico".The video shows a young boy befriending a griffin-like creature, which appears to combine the functionality of Yorda from "Ico" with that of Agro and the colossi from "Shadow of the Colossus", acting both as a companion and as a form of transportation which can be freely climbed upon.E3 2009 revealed the project's release title as "The Last Guardian".
