The collaboration between Adult Swim and Valve turned out to be . . . a hat. Those that sign up for the newsletter will receive a chicken hat for Team Fortress 2 . . . though that won’t be it between Adult Swim and Valve.
“You can rock it no matter what your class, you lucky so-and-so,” writes Adult Swim. “Sign up for the newsletter below to receive your Steam promo code. Then you’ll be the first to know when we have MORE new stuff coming down the ol’ Steam pipe-hole . . . Because this ain’t the last you’ll hear from Adult Swim and Valve. Stay tuned.”
