Birthday mode, also sometimes called party mode, is a server mode that enables various "silly gibs" to be used alongside the normal gibs. Until 2013, it was activated on August 24, the release date of the original Team Fortress in 1996. In 2013, it was activated on August 27 until 2015, where it was activated on August 23. It can manually be enabled on servers by using the setting tf_birthday 1 in the server.cfg file.

Many of the gibs seen in this mode are used in the low-violence version of the game as full-time replacements. A beach ball appears in BLU's spawn room at the beginning of the round and may be propelled by most attacks and the Pyro's compression blast. Health kits are replaced with birthday cakes and ammo packs are wrapped with a bow in a style similar to a present.


Prior to the August 23, 2011 Patch, birthday mode would automatically draw a party hat on top of the classes' heads. However, this was changed and the party hat became its own item that can be chosen like other hats. This prevents a number of clipping issues the party hat had with non-default hats.

During that time, birthday mode completely disabled the use of violent gibs, and blood was replaced by balloon particles. Some violent gibs are now spawned along with presents and other silly gibs. Birthday Mode is similar to Pyroland while using Pyrovision Goggles.

Scoring a crit used to play a cheering sound effect rather than the normal crit impact sound, but this was moved to the TF Birthday Noise Maker.


Main article: Silly gibs

Birthday mode uses both the normal gibs and silly gibs that low-violence versions of Team Fortress 2 use.

Unused content

  • The original models for the party hats are still in the game files, unused, under the path models/effects/bday_hat.mdl, while the Party Hat cosmetic is instead located at models/player/items/all_class/bdayhat_.
    • Likewise, every class' player model still has an attachment related to the old version of party hats, named partyhat. This attachment would originally place the model properly on top of their heads, but it has since been changed and no longer fits properly.
