About Poker Night at the Inventory
***Not Compatible with Mac OS 10.8.x and above***
Prepare for a different kind of poker night in a very different kind of club. In Poker Night at the Inventory, you'll deal with Penny Arcade's clever, cunning Tycho, Team Fortress 2's hulking Heavy, Homestar Runner's self-proclaimed "awesome icon" Strong Bad and the hyperkinetic "rabbity-thing" from Sam & Max. These characters come together in ways some never thought possible, in a setting few would have predicted. Unlock new TF2 items by beating The Heavy, Max, Tycho, or Strong Bad at high stakes games of poker.

The Enthusiast's Timepiece: Tycho's favorite timepiece (equippable by the Spy)

License to Maim: Max's Badge (equippable by all classes)
The Lugermorph: A second chance at Max's personal armament (equippable by the Scout and the Engineer)

The Iron Curtain: The Heavy's first love (equippable by the Heavy, obviously)

Dangeresque, Too?: Strong Bad's styling glasses (equippable by the Demoman)
