Tux is a promotional cosmetic item for all classes. It is a stylized version of the Linux mascot, Tux the Penguin, worn on the character's belt.

This item has three styles, "Normal", "Demoman" and "Pyro". While the Demoman style simply gives Tux an eyepatch on his left eye, the Pyro style removes his head completely and replaces it with the Pyro's gas mask, as well as changes the flippers to be grey and boot-like.

This item was awarded to players who launched Team Fortress 2 using any Linux distribution between February 14th, 2013 and March 1st, 2013.

The Tux was still obtainable in-game past the original stated date. It was not until mid to late-March that the Tux finally became unobtainable.

Although initially promised[1] for the Tux to become tradable once the promotion was over, this has not been done, and it is unknown whether it will eventually happen or not.

When players equipped with this item kill an enemy unassisted by another player, the killfeed shows everyone in Pyroland that it gets the assist, with its custom name if it has one.
