The Unusual quality is an item quality used on cosmetic items, taunts, and weapons. Unusual quality items have special particle effects attached to them, and are considered to be some of the rarest items in Team Fortress 2. There are currently 631 cosmetics that can have one of 307 total effects, 106 taunts that can have one of 155 total effects, and 44 weapons that can have one of 5 effects. Unusual items can primarily be obtained through opening Mann Co. Supply Crates and cases. There is a less than 1% chance of obtaining an Unusual quality item through crates and cases. Unusual quality items can be obtained in any crate or case, but the effect pools may vary depending on the crate or case series.

The hexadecimal color code for Unusual items is #8650AC, a deep purple.

• Unusual effects may sometimes detach from the player after moving enough or taunting.

• Sometimes, a weapon Unusual effect can block a player's first person view, only resetting once the player dies or has their loadout refreshed.
• Unusual taunt effects that attach to the player's body do not appear properly in the loadout or inspect menu.
