Development Timeline of Shadow of the Colossus

Shadow of the Colossus, like any game, had several different development periods. This is a list of all of the known ones, with details for each one. The dates were taken from the ICO and Shadow of the Colossus Collection Booklet.

They are divided into "World Eras", each marking a major change in the shape of the game.

• World Era 0 = Planning > Prototype
• World Era 1 = Test Stages > Parts Library Map
• World Era 2 = Height Map > 24 Colossi Map
• World Era 3 = Colossi & Map Reduction > Final Shape

Period names are subject to change

World Era 0

Planning Period

In September 2001, the presentation of the new concept to the staff was done. Two types of games were conceived, a game for a male audience and a game for a female one. The former with strong action was adopted.

Sketches of designs drawn by Kazuhiro Numata for the boss design of the pilot movie, shared on the developer's twitter account.

In late-January 2002, the first storyboard draft for a presentation demo was completed.

In March 10th 2002, the staff rode horses on a training camp at Mount Fuji. The horses were observed and their movements studied. The motivation of the staff was increased.

Prototype Period

Nico tech demo - Shadow of the Colossus

In mid-May 2002, a real-time demo depicting a group of horned boys taking down a colossus was completed. It is available in the Nico bonus DVD, showing the battle against the colossus that would turn into the 2nd colossus. However, the background soundtrack in the video from the Nico DVD wasn't yet created. As stated in the World of Fumito Ueda artbook, originally the demo used the opening track of Sam Raimi's Spider-Man as Fumito Ueda thought it would be perfect for it.

In June 2002, Team ICO began trial production of "NICO (Tentative name)" and developed a test version with a small group of people. Ueda worked with coders on the deformation collision for six straight months which involved creating a flexible pole, "kind of like a plant" and having the player character climb on it.

In July 2002, started recruiting staff on the web and in magazines. Since the scale of development would be larger compared to the previous work, Team ICO was recruiting ready-to-work staff from the general public.

World Era 1

Masked Boy Period

In May 2003, Team ICO began production of "NICO" and presented a prototype at an internal meeting. Development approval was given after the first presentation. This is the time in development when the player was still a horned boy in a mask. The colossi were few and still rather simple and were tested in separate stages with no seamless map; that is, the open world divided by quadrants from the final game.

Clips of it are available in the Nico bonus DVD.

Horned Boy Period

Later in 2003. Many colossi were in the works and their environments were taking shape. The player character lost the mask, while still keeping the horns, blue shirt and pants. Development on the unused colossus named Saru stopped around this period.

In July, the first monitor meeting was also done, which was a survey of the public's reaction to the game's core design.

Some pictures of the artbook and clips featured in the Nico bonus DVD show this phase.

Full-scale Development Period

By September 1st 2003, the staff was moved from the building on Nakano-Sakaue to Aoyama. Full-scale development began in the new studio. The player character had developed further, losing the horns, and having a 'tunic' instead of the shirt and pants of earlier phases. One of the key aspects of identifying this phase is by looking at the simplistic HUD.

Pictures and clips of it are available in the artbook, in the Nico bonus DVD and in trailers.

Footage of the battle against the second model of the 13th colossus, barely changed from the previous phase.

Parts Library Map Period

At the start of 2004, the HUD was changed again, this time lasting a long time, only being replaced in the final phases. The first seamless map was also created around this period using the "parts library", which was mostly flat. Many colossi were placed on a quadrant with no arena, such as the case with Spider. Any footage that was taken on a vast dry area was in this first seamless map. G0, B2 and the old I7 found in the preview version and earlier are all remnants of this time. Development on the unused colossus named Griffin stopped around this period.

Pictures and clips of it are available in the artbook, in the Nico bonus DVD and in trailers.

World Era 2

Height Map Period

After the start of 2004, Wander's model was changed once again, having a blue headband (previously red), improved facial features and leg wrappings.

There also existed a later version of Wander with long sleeves instead of the short ones from previous phases as seen in the brief Leo's Cave clip featured in the Nico bonus DVD. The clip also showed the game was starting to render distant quadrants instead of just the one you're currently at, and the world map was also getting improved over time, by auto-generating land with a height map that would serve as a base for most phases going forward, and then modelling by hand.

Pre-Showcase Period

Mid-2004, the game's title was finally chosen as "Wanda and the Colossus". The seamless map was further developed and the arenas were all placed. The sky still lacked the yellow tint of the next phase and its seamless loading still didn't look up to par. The player character's design was very close to completion, having brown clothing instead of the blue one.

Pictures of it are available in the artbook and in the Nico bonus DVD.

TGS Period

Mid to late 2004, the yellow tinted sky was added and many promotional pictures and footage were taken in order to show the press, making it the most famous beta phase. The game was shown to the public in order to garner reactions and adjust the game in response.

World Era 3

Reduction Period

Late 2004 to the start of 2005, due to the reception, lack of time, lack of budget and some developers leaving, several colossi and locations were decided to be removed before being finished, eventually leading to the final version we have today. The player character was unchanged from the previous phase.

A short teaser released in December 2004 shows the early design of the 2nd colossus. The music was also added to the game around this point.

Arms Period

Throughout 2005, several builds were distributed to the press, game conventions and the like. The game was already in its final touches, with the player character finally being the finished Wander. It is what is known by the community as the "Arms build", as the HUD has the text "Arms" on it.

In the pre-E3 showcase that took place in April 2005, Sony showcased the game and revealed that the name was changed to Shadow of the Colossus to releases outside of Japan.

The stone eyes of previous builds were replaced by animated swirling eyes.

Some textures for the logo in the main menu for several builds from this period are listed in the PS3 data sheets, the dates of the build are in their names. Below is a list of them and a short description if information is available:

• April 18th 2005 - E3 Build 1
• April 19th 2005 - E3 Build 2
• April 25th 2005 - E3 Build 3
• May 2nd 2005 - E3 Build 4
• May 12th 2005 - E3 Build 5
  • This is the build dubbed the E3 Demo, as it was the one playable at E3. The bridges and paths are all blocked off, but the rest of the map can be accessed by modding or hacking.
• May 13th 2005 - E3 Build 6

Besides these, there are a few other builds around this period (released officially or not) that are publicly available. They are:

• June 21st 2005 - OPM Demo
  • Despite being also named "E3 Demo" in the main menu, the OPM Demo is not the same as previous E3 builds. Bridges and paths are blocked off like the E3 Demo, although the rest of the world map is not in this build, with only the 9 central quadrants being in the files.
• July 7th 2005 - PSU Preview
  • This build is like the E3 Demo and Preview versions, in that every quadrant is present. Unlike the E3 Demo version however, all quadrants are accessible without any modding or hacking needed. However, only 3 colossi are in this build, the 1st, 2nd and 3rd.
• July 11th 2005 - PSU Demo
  • Just as the OPM, this demo only has 9 quadrants in total.
• August 9th 2005 - Preview
  • The Preview version, despite not having the "Arms" text in the HUD, can also be considered part of this period.

Release

October 18th 2005, the final American (NTSC-U) version is released, receiving critical acclaim from reviewers. In October 27th 2005 the Japanese (NTSC-J) version released, and then in February 2006 the International (PAL) was released to the rest of the world.
