Astro Boy: The Video Game is a side-scrolling beat 'em up and shoot 'em up combo based on the 2009 animated 3D movie of the long-running character from manga and anime. Astro Boy must save Metro City from President Stone and his robots while fighting through levels on the ground and in the air.
In the game, Astro Boy can fight combination moves, shoot a laser from his fingertip, and use special attacks if his energy meter is powered enough. These include an Arm Cannon, Butt Machine Guns, and Absorb (recharges a portion of health). He can also find different power-ups and costumes in hard-to-reach and hidden areas.
The game features single-player mode, as well as 2-player multiplayer co-op on PSP where the second player controls another Astro Boy with a different costume. In Story Mode, if one person dies, they can rejoin the game later with full health after some time elapses. However, if both die, the game is over and must be started again. There's also an Arena mode where both players fight robots to determine a winner with the most points.
