The Last Guardian Wiki

The development behind The Last Guardian is a complex story, arising largely from earlier games in Team Ico's history.


Last Guardian is partially based on the interaction between the protagonist of Shadow of the Colossus and his horse, Agro. Much like Team Ico's titular game Ico, the concept of a follower who plays a central role in progressing the story and gameplay was a huge driving force in the development of The Last Guardian; lead designer Ueda stated that the interaction and relation development, especially the development of "emotional attachment" between main character and side character, would play a huge role in The Last Guardian. Similarly, the concept of climbing a mammoth creature would carry over to Trico itself, and is considered by many to be a combination of the mechanics in Ico and Shadow of the Colossus; Ueda has stated that "there's a bit of each of those [games] in there".


Ueda has stated that he wants Trico to behave as realistically as possible (at least for an animal that doesn't exist), detailing that he wants to avoid "the unnatural idiosyncrasies of the virtual animal" which occurs in most games. When developing Trico, the designers purposely made the animal a bit strange, stating that the design was "deliberately unbalanced because looking strange was important here". Certain interactions and subtleties were added to Trico early in development, such as facial tics (similar to those a cat would make when being petted, challenged, etc.) and detailed keyframes for motion as opposed to the industry standard motion capture, which lent an eeriness and serenity to earlier character models.

The Boy

The "main character" of The Last Guardian was also considered early in development; fluid motion and subtleties became even more important, because gamers often inject themselves into human characters, making subtle movements (such as the fact that when near a wall, the Boy will place a hand on it for balance) important for absolute immersion. Life-like animations, accurate rendering models, and even the sex of the character were hard thought and heavily-developed aspects of the early game.

The Engine

The engine for The Last Guardian features a full physics emulator, a departure from earlier Team ico games. Ueda has stated that the trailer, in which a boy throws a barrel at a creature, who then bites and destroys it, was fully seated in that physics engine, and was used as a test to demonstrate it's power. The engine also includes versions of the previous AI systems used by Team Ico's games, but with an advanced interlocking system allowing for more complete artificial intelligence. Ueda has also stated that the engine renders the effects of wind on each of the creature's feathers.

  • March 2014 - Scott Rhode states "we're not not going to announce what platform it’s coming on, who’s working on it, who’s involved.

  • June 2014 - IGN suggests that The Last Guardian is cancelled based on an internal meeting with a Sony Russia executive.

Yoshida states that the game was changed from PS3 to PS4 because of technical concerns, and that "the announcement trailer of 2009 wasn't representative of how the game actually performed - but was "specced up" for the occasion [...] the game was running on a much lower frame rate." He stated that "there were a lot of technical issues. The game was not performing at speed. The game was running on a much lower frame rate. Some features were still missing. [...] It was clear that the team had to make a compromise in terms of features, as the PlayStation®3 hardware struggled to cope with the game's vision. [...] So it was clear that the team had to make a compromise in terms of features and number of characters so while they were taking time, the engineering team ported the code on the SPU [processors of the PS3] to improve the performance, but it was taking lots of time. [...] But, in the meantime PS4 arrived, the development environment was available. So in 2012 it became apparent we should move it to PS4 to achieve the visual [ideal.]” He stated "[the team has] a certain level of confidence about the launch window, which is why we showed it.”
  • September 2015 - The Last Guardian is shown at Tokyo Game Show with a giant animated and reactive installation of Trico.


  • May 2016 - The Last Guardian is stated to appear at Tokyo Game Show 2016. A 2016 release date has been confirmed[7].
