The Last Guardian and previously referred to by the working title “Project Trico”, is an upcoming adventure game developed by Team Ico, to be published for the PlayStation 3. Existence of the game was first hinted in a January 2008 job listing on Sony Japan’s corporate website, which depicted a single screenshot of the upcoming third Team Ico title for the PlayStation 3 and advertised open positions for the development team. A video released via the PlayStation Lifestyle blog in May 2009 shows early footage of the game with its working title, Project Trico, reportedly from a proof of concept trailer that had been circulating internally at Sony for over a year.

At E3 2009, Sony unveiled the latest version of the same trailer, that is somehow similar to the early one, but with various differences: the boy has a different character design, the details in the scenario are improved and the exterior of the palace that they explore was changed. Thanks to Pikol’s Youtube Channel we can see a nice comparison between the beta trailer and the “final” one!
