You are put into universe where you don't play as a human, or a machine. You are a gravity field and you have to take care of your planet. Be aware of other bigger planets, since they can easily destroy you.
If you want to play, you'll need:
After downloading a installer with the link at the top of this page, the installer will update itself and download the latest version of the game. Any time you run the game it will check itself against the newest release so your game is still kept up to date.
Every player has assigned planet and a graviton to him. Player wins when his planet is the last of the players planets left in a game. Only way the player can affect the game is by assigning a position and a force type of his gravitational field (either repulsive or attractive).
You control your gravitation force by your mouse, and move around by W, S, A, D keys. The spacebar toggles the attachment of the camera towards your planet.
