Look for Astro Boy, the video game this fal on Wii, PS2 and PSP.
It'll allow players to control the title character, a young boy robot with incredible powers. Your mission will be to save his home, Metro City, from evil President Stone and his robot army. To do battle, you'll use Astro's arsenal of weapons which includes, seriously, butt machine guns as well as finger lasers and an arm cannon.
The game is based on the upcoming feature film of the same name.
