The Jarate is an unlockable item exclusive to the Sniper class. It will replace the Secondary weapon slot. Jarate takes the form of a closed jar of what appears to be the Sniper's urine. When used on enemies, they will take 35% more damage from regular damage for a short amount of time. The extra 35% of damage will result in an instant mini-crit. Also, when the Jarate is thrown and broken, the urine will be able to short out the cloaking devices of Spies. The Jarate's effects will be washed off instantly when jumping into water. When used on teammates and/or yourself, Jarate will extinguish any fire effects caused from Pyros.
- The Jarate was featured in 2 "Meet The Team" videos. It appears once during "Meet The Sniper", when the Sniper is busy doing his job. It's second appearance is in "Meet The Spy". When the Spy is about to backstab the Sniper, Jars of Jarate can be seen (if you look closely).
- The Jarate started out as an April Fools joke.
