Missing.tf works similarly to other Team Fortress 2 backpack viewing sites, only it works in reverse!
Have you been away from TF2 for a while and you're not sure what you've missed?
Maybe you're trying to collect every single hat or weapon in the game?
Missing.tf will display all of the TF2 in-game items you don't currently have!
Please enter a Steam ID in the box above, and press "Go" to Find Out What's Missing!
Note: Some backpacks may take up to a minute to load! Please be patient!
