You've seen the movies, you know what to do.

battalion is a giant monster game where you are a giant monster fighting to survive against the military while causing as much destruction as you can. You can choose to be one of four possible monsters: Googelon, Techs, the Vapour or Flutter.

• Googelon: An idealistic young monster from Osaka bay heads off to America to seek his fortune.
• Techs: A communications satellite gains consciousness while broadcasting a Sam Peckinpah retrospective. After several more hours studying the films of Sergio Leone and John Woo, Techs heads down to Earth, ready to integrate into society.
• the Vapour: A dangerous experiment on a college campus goes terribly wrong an the vapour escapes from a dorm room after a really excellent party.
• Flutter: A bug zapper is accidentally cross connected to the atomic pile of a nuclear reactor. A thunderous ZAP! The sky is filled with blue light... and something else.

Your sudden arrival caught the military off guard, but they're on their way. The military is equipped with Tanks, Rocket Launchers, Maser-Tanks, Helicopters, Jet Fighters, and Bombers. More powerful weapons are currently under development and will be deployed against you when available. And if the situation looks hopeless...

Your current health is displayed in a coloured bar at the top left corner of the screen. You lose energy when you move, activate your weapon, or get hit. You slowly regenerate energy throughout the game. When your energy runs out, you die and the game is over.

You get points for destroying military vehicles and buildings (but not trees.)
