We usher in the holiday season with new merch in the Valve company store...
We’re pleased to offer three new lithographs in our collector's edition prints. Each of the lithographs features concept art from Orange Box games-Portal, Half-Life 2: Episode 2, and Team Fortress 2. The first hundred of these limited-edition runs are hand-signed and numbered by the artist and embossed with the Valve lambda.
If Portal’s Weighted Companion Cube and cake could express holiday cheer-and we remind you that they cannot-they’d send an Aperture Laboratory Holiday Greeting Card. This limited-edition pack includes 15 Portal-themed greeting cards-three each of five different sets, each with a unique holiday greeting inside. Slip in a new Aperture Laboratories parking sticker, available separately, to warm the heart of your favorite Portal jumper.
Also in stock for the holidays: The Orange Box gift certificate pack. You get two gift certificates for the Orange Box, each presented in an Aperture Laboratory Holiday Greeting Card. As a bonus, the gift certificates save you 10% off the regular retail price.
You can pick up Activision’s action-adventure game GUN for just $9.95 USD, a 50% savings, this weekend only. Saddle up."
