Valve, the company behind Half-Life and Steam is teaming up with the not-for-children US cable network Adult Swim to collaborate on a Team Fortress project.

Both companies remained vague as to the extent or nature of the collaboration. A promo page on Adult Swim’s website reads, “Coming next week Adult Swim & Valve are teaming up for something that you'll probably enjoy. To learn how their video game peanut butter will be getting in our network's chocolate, come back next week. Also: You'll want to sign up for the newsletter. You've been warned.”

Adult Swim has also been directing twitter users to the URL: http://adultswim.com/teamfortress. The link redirects browsers to the page with the above text.

The project will be unveiled next week.
