Play Astro Boy: Omega Factor Online

Summary

Astro Boy: Omega Factor shines as a 2‑D beat ’em up on the Game Boy Advance, blending Treasure’s fast‑paced action with Osamu Tezuka’s sprawling universe. You guide Astro through seven episodes, stacking punches, kicks and his signature laser while a filling EX gauge unlocks flashy super attacks—from a high‑power beam to a screen‑clearing gun. Each opponent you defeat becomes part of the titular Omega Factor, letting you spend points to boost health, strength or flight speed and to reveal hidden paths. The title famously includes 47 characters from Tezuka’s broader canon, an homage that lets fans run into faces beyond the original Astro Boy series.

The North American launch in August 2004 arrived after Sega delayed the release to match the new TV series, using the gap to add extra enemies, tweak difficulty and fix frame‑rate issues. Critics raved – Metacritic scores sit in the mid‑80s, with outlets praising its "lavish animation" and labeling it a technical marvel, even earning a spot in *1001 Video Games You Must Play Before You Die*. Though occasional level repetition shows through, the visual flair and polished combat keep the experience memorable.

Storyline

Astro Boy: Omega Factor drops the young robot with human emotions into a disaster‑riddled Metro City, where he must rescue civilians, battle hammer‑swinging bats, and power through a plasma‑leaking plant using six super‑powers. He travels to places like Cruciform Island and the lost continent of Mu, meeting over 50 Tezuka characters—Atlas, Dr. O’Shay, Zoran, Dr. Tenma, and many others—who teach him tenderness, justice and courage. The Omega Factor system forces Astro to develop his human side to bridge the gap between people and robots.

The story is split into two episodes, Birth and Rebirth. Birth follows Astro’s early quest and ends with the orbital Death Mask deeming robots too dangerous, allowing Sharaku to seize Earth. Rebirth sees a phoenix‑like being revive Astro, granting time‑travel powers so he can return to the start and stop the Death Mask. Elements like time travel echo Tezuka’s Marine Express, and robot‑rights themes come from the 2003 Astro Boy series.

An in‑game encyclopedia, the Omega Factor, catalogs every cameo with detailed bios, showcasing the breadth of Tezuka’s canon. Ultimately, the game’s core theme is Astro cultivating his humanity by absorbing the impressions of the many characters he meets.
