If you live in Burbank, California—or just happen to be there Friday, October 23—you should drop in on Insomniac for a Ratchet & Clank Future: A Crack in Time party.
Last year, the developer threw a similar Community Day to celebrate Resistance 2. Apparently, it was such a success that they've decided to give Ratchet & Clank the same treatment with rare swag giveaways and free food. There will probably be less crazy-fragging in multiplayer, given that it's not Resistance, but you still probably get to play the game.
Only the first 120 people are getting in, so be sure to hit up Insomniac's Facebook event page to make your intent-to-arrive known. Then it's only a simple matter of showing up and boom! Ratchet & Clank party for you!
