History VideoGame / AstroBoyOmegaFactor

* CharacterCustomization: The game gives no guidelines as to where to put your upgrades, but you'll max out by halfway through Rebirth if you find everyone. If needed, you can relocate your upgrades.

** An entire ''subplot'' necessary to complete the game is initiated in a rather unintuitive manner: [[spoiler:by ''repeating the tutorial level'', since that's the only place barring cutscenes where Astro interacts directly with Dr. O'Shay (Astro will confront him about Dr. Tenma). Made worse by the fact that the game discourages you to do so to begin with by having O'Shay ask if you've forgotten the basic controls when you start]].

* LetsYouAndHimFight: Astro fights several heroes / investigators who think Astro is a criminal, or they're the type who fight first and ask questions later.

* NintendoHard: On Easy you begin each life with with, ridiculously, 30 Super attacks and can stock up to 99 of them and enemies deal very low damage. On Hard? Nightmare. Enemies will tear about half of your HP with the lightest of attacks, you can have only 3 Supers now and there are MANY things that can kill you in a single hit. Let's state that we are not talking about bottomless pits or death spikes. Rebirth Mode is a living hell on ''any'' difficulty. What's worse is that there barely are any recovery items in each chapter and some of them are the level ups that only work once.

* OffscreenStartBonus: [[spoiler:Kennedy and Unico]] are both just off-screen when you start certain areas.

In terms of gameplay, this is a {{Platformer}} where Astro can jump and air dash ([[InvulnerableAttack he's invincible while dashing.]]) Astro has a basic punch combo, although he may freely [[PunchedAcrossTheRoom kick enemies away]] or [[FingerGun fire a finger laser]].) He also has access to three special attacks that he can build energy for.

There are also a few levels where Astro exclusively flies. He relies on his finger laser for offense, but can dash and use his specials normally.

* {{Atlantis}}: Mu, pretty much.
* BackFromTheDead: [[spoiler: Astro]] at the end of the first loop, revived by Phoenix.
* BadassAdorable: Astro, Denkou, Pook and the list goes on…

* CharacterCustomization: The game gives no guidelines as to where to put your upgrades, but you'll max out by halfway through Rebirth if you find everyone.

* EarnYourHappyEnding: Astro has to use the Time Skip ''liberally'' in order to set right all that is wrong.

* GrotesqueCute: [[spoiler: Nuka while in Death Mask form.]]

* HitPoints: But by the three-quarters point of Rebirth, they stop mattering.

''Astro Boy: Omega Factor'' (Known in Japan as ''Astro Boy • Tetsuwan Atom'': ''Atom Heart no Himitsu'') was based on Manga/AstroBoy, released in 2004 for the GameBoyAdvance after the Anime's 2003 Reboot. It was developed by {{Treasure}} and Hitmaker and published by {{Sega}}. Many consider this game an aversion of TheProblemWithLicensedGames, and a fitting tribute to OsamuTezuka.

** Nuka combines elements from her original 80s anime incarnation as well as ''Prime Rose'''s Death Mask, Bem from the original series' ''Earth's Last Day'' storyline (humanoid control system for a weapon of mass destruction) and Mitchy &/or Tima from ''[[Anime/Metropolis Metropolis]]'' (created on Duke Red's orders using the power of Omotanium, plugged into a machine that can affect the sun).

** References to ''GunstarHeroes'' are also present: the background in one level features buildings that have signs reading "'''Gunstar'''", Pook refers to his different forms as "Forces" (similar to the ''GunstarHeroes''-boss, Seven Force), and two songs from ''GunstarHeroes'' were remixed for ''AstroBoyOmegaFactor".
