Expiration Date is 15 minute animation from Valve featuring the Team Fortress characters.
Engineer and Medic make an unsettling new discovery while experimenting with the teleporter. Meanwhile, Scout stops insulting Spy long enough to ask him an embarrassing favor; the Administrator’s clerical assistant/cleaner/murder expert Miss Pauling races to bury some incriminating bodies; and Soldier makes a new metal friend.

Valve has a flair for animated films; the series of brief Team Fortress character introductions like “Meet the Pyro” and “Meet the Medic” for Team Fortress has had more than 85 million views on YouTube and was widely hailed as a genius marketing campaign.
