Facility-01

Mad Milk is a community-created secondary weapon for the Scout. It is a generic glass bottle of a non-milk substance with no cap. The liquid inside sloshes with the player's movements.

Unlike the other drinks available to the Scout, Mad Milk can be thrown at enemies as a projectile, and, much like other throwables (such as Jarate), explodes if left in the air for too long. Victims continually drip white beads of substance and are notified by a corresponding white droplet on the HUD, next to their health meter. It is possible for a player to throw a "critical" Mad Milk with a team-colored effect, but the effect is purely cosmetic.

Enemies caught within the 200 Hammer units splash radius are soaked in the contents of the jar for 10 seconds. When a target is soaked in Mad Milk, 60% of all damage taken is returned as health to any attacker, with the only exceptions being damage done by an Engineer's Sentry Gun and afterburn damage. The healing provided by Mad Milk does not overheal players.

Mad Milk can also extinguish teammates on fire (as well as its user) and reveal enemy Spies. Unlike Jarate, however, it does not short out the Spy's Cloaking device; invisible Spies under the effects of Mad Milk remain invisible and do not have their disguises or team colors revealed, but the dripping white beads make them easy to locate.

Aside from dying, the only ways to prematurely remove the effects of Mad Milk are visiting a Resupply locker, Charging, being submerged in water, or being healed for an extended period of time.

If the Scout wielding the Mad Milk extinguishes a teammate with the item, the cooldown timer is instantly filled by 20% (leaving only a 16-second time period to recharge as opposed to the normal 20-second timer).

If an enemy Pyro manages to deflect the Mad Milk back at the Scout or any of his teammates, the enemy team can use the deflected milk to restore health by doing damage. Similarly, a deflected Mad Milk is also able to extinguish any burning enemies within range.

While playing in colorblind mode, a white raindrop icon appears above any players sodden with the weapon.
