Officially announced at the Tokyo Game Show 2010, The ICO and Shadow of the Colossus Collection is a PlayStation 3-exclusive re-release of the classic PlayStation 2 games Ico and Shadow of the Colossus. Both games are on one Blu-ray Disc, and feature full 1080p HD remastering (including a smoother frame rate), 3DTV support, and Trophies. Also, the box contains a PlayStation Network voucher for a dynamic XMB-theme and video content from Ico, Shadow of the Colossus, and the upcoming The Last Guardian (the video features are on the disc in the US version).
The HD versions are based on the European release which means that the games contain additional features not present in the original North American version on the PS2. Alongside the different artwork, the Ico remastering contains altered puzzles from the original release. It also includes the ability for players upon completing the game to allow them to restart and see the English translation of Yorda's speech and make use of the two-player mode that was not included in the original American release of the game on the PS2.
Shadow of the Colossus meanwhile has a slightly different ending as well as some small tweaks to the gameplay. The gameplay changes are that the stamina system depletes slightly faster than on the PS2 and so climbing is more difficult and the player is move easily knocked off their balance or tossed around whilst on top of a Colossus. The game's framerate is also slowed down upon defeating a Colossus for several seconds as the player strikes the killing blow rather than immediately transitioning to the death animation as it did on the PS2 release.
The collection was initially due to be out in Spring of 2011, but in April, Team Ico announced that the HD collection along with their current game, The Last Guardian, would be delayed. A Japanese trailer was released in the run up to E3 2011 stating a Japanese release date of September 22nd 2011. In Japan, the games are released separately on disc, while also being made available in a "Limited Box" which also includes an art booklet and a code for downloadable content. Sony's US and European PlayStation blogs confirmed the game's final release date as September 27th and 30th, respectively.
