Electronic Arts has unveiled a new trailer for the second expansion pack to the "Sim Everything" game Spore. Galactic Adventures, currently slated for a Spring 2009 release, further develops the space phase of the game.

Galactic Adventures allows you to beam your creature onto planets and perform missions. According to the trailer, missions will include standard exterminations, arena battles, and rescuing a princess at the end of a maze. Considering how most of the Spore creatures look, the princess is probably hideous. There's also another mission where your spaceship crashlands and you must destroy an enemy mothership to escape.

Though it's not mentioned in this trailer, earlier announcements regarding Galactic Adventures suggested that it would come with an Adventure Editor as well. This Adventure Editor would allow players to create their own missions and then share them with friends. It's the sort of thing you'd think EA would brag about every chance they got but maybe they're planning on releasing a trailer devoted solely to singing its praises in the future.
