Today's Team Fortress 2 - The Sniper vs. Spy Update further paves the way for the upcoming Sniper/Spy update for Team Fortress 2, introducing Jarate, a martial art involving wizz jars some say was invented by Howard Hughes: "Jarate is a thrown jar that splashes upon impact. When splashed on enemies, they take 35% more damage for a period of time. Jumping in water will wash off Jarate. Jarate is also able to short out Spies’ cloaking devices. When used on teammates, Jarate will extinguish any fire effects." There's a pisser of a comic accompanying the update.
