10 Embarrassing Accidental Video Game Leaks
2. The Last Guardian
It had been four years since Team ICO's spectacular Shadow of the Colossus, and all they had released pertaining to their next title was a single image showing a chain hanging down a well.
Suddenly out of the blue one day in May 2009, Playstation Lifestyle blog posted a lengthy trailer for a game featuring the same chain, as well as a young boy co-operating with a giant, griffon-like creature, surrounded by environments reminiscent of ICO and Shadow of the Colossus.
The footage shown was that of a very early version of the game, but it seemed far enough along that everyone began to get excited to see more of Project Trico. A few weeks after the leak, Sony did reveal The Last Guardian at E3 2009 with a planned release of 2011. Little did we all know that the game wouldn't release until December 2016, over 7 years since the initial leak, and after 9 years of total development.
