Transformers is a 2004 video game for Sony's PlayStation 2, developed by the Australian-based Melbourne House, and published by Atari. It is based on the Armada series, though it does not follow any pre-established storyline. It was released in the US on April 11, 2004, and in the European market on April 7 of the same year. In September 2005, Atari released a "Director's Cut" of the game exclusively in the UK. The only difference between this and the original was a bonus DVD containing a "Making Of Documentary".
