Astro Boy: Omega Factor, released in Japan as Astro Boy: Tetsuwan Atomu (アストロボーイ・鉄腕アトム), is a beat ’em up video game developed by Treasure and Hitmaker, and published by Sega. The game was released for the Game Boy Advance on December 18, 2003 in Japan; August 18, 2004 in North America; and February 18, 2005 in Europe. The game is based on Osamu Tezuka‘s manga and anime franchise Astro Boy. However, it also features characters and plotlines from the artist’s entire canon of work.
Omega Factor is a beat ’em up game starring Astro Boy, the main character of the Astro Boy media franchise. Astro attacks enemies using high-powered punches and kicks, which can also knock enemies into other ones and destroy them as well. Using attack moves slowly fills a gauge at the top of the screen. Once the gauge is filled, Astro is able to perform a special attack; rather than simply helping the player, these are required in some situations. Astro is also able to fly using rocket power, which is also sometimes necessary.
Astro’s physical performance improves throughout the game. Every non-player character the player meets scores a point that can be used to improve one of Astro’s stats, such as strength or flight speed. This is generally not necessary to beat the game, but the incremental stat increases can make the game easier, as well as allowing the player to find hidden areas in levels. The game features two difficulty levels in the Japanese version, and three in the North American and European versions.
