IBM has been touting virtual worlds like Second Life a lot lately. But it’s also getting into the game. For Earth Day, IBM has designed a virtual world game dubbed “Power Up.” It’s a free 3-D multiplayer virtual world game on a planet called “Helios.”

Players create avatars to ride through rugged mountains and search through junk yards to help rebuild broken wind turbines, solar panels, and dams. They have to avoid floods, sandstorms and SmogGobs. The mission is to save the planet. IBM says the world is targeted at teens who have an interest in fantasy worlds as well as a desire to learning about energy conservation and science.
