Adult Swim and Valve are working together to collaborate on some… secret thing. It is believed that it might be the “Meet the Pyro” video or perhaps a long rumored Valve game project for this year.

“To learn how their video game peanut butter will be getting in our network’s chocolate, come back next week,” adds the teaser, which offers a newsletter sign-up for more info when they’re ready to actually talk about it.
