| Special Item: Tycho|
Knock out Tycho after he's bought in with his special item.
- The Enthusiast's Timepiece was added to the game.
- [Item schema update] The item could no longer be obtained via the item drop system or crafting.
- The Cloak meter displayed on the watch does not properly correspond to the actual amount of Cloak available, similar to Dead Ringer.
- When Tycho first shows the watch to Gabe, the co-star of the Penny Arcade webcomic, Gabe kills Tycho to obtain it. The watch has since changed hands repeatedly through the characters murdering each other. 
- The Cloak meter emulates the Pac-Man derived logo commonly seen worn on Gabe's shirt as well as a tattoo on his arm.
- The version of the watch presented in Poker Night at the Inventory is stained with blood on the left of its face. However, the version obtained in Team Fortress 2 does not have blood.
- If the Heavy wins the Enthusiast's Timepiece he announces to the table; "I will put this in my box of things I collect from dead enemies."
