Capcom's throwing a party tonight to celebrate the launch of its Xbox 360 game Lost Planet.

You're invited, but only if you're in, near, or visiting San Francisco. And it's 18 years and older, too, apparently.

Capcom promises to have multiplayer competitions, lots of prizes, a T-shirt making station where you can create your own Lost Planet clothing. Oh, and if that's not enough, master LEGO builder Nathan Sawaya will be in attendance. Check out the slick invitation for all the details...
