Well, there is an email from Jeep that was received this morning about information on the Summer Sale. Also, there is something fishy going on within Team Fortress 2.

Email Contents From Jeep:

Hey Aaron! Good to hear from you. It's so cool that a community formed around the Portal ARG and continues to stick together. I hope you're playing ARGs other than ours since, "Valve Time." That Surgeon Simulator one was pretty awesome! http://www.pcgamer.com/2013/09/27/surgeon-simulator-2013-arg-solved-unlocks-extraterrestrial-surgery/

Anyway, I'm not currently working on an ARG. It's a big company, so there may be something in the works that I'm not aware of, but your best bet is to keep an eye on these mysterious cards...
