Cheeseburger

"A yummy cheeseburger. Replenishes 50 health points when eaten." In-game description

The Cheeseburger is a support weapon for Scout that heals 50 hp upon use, and can be used every 15 seconds regardless if Scout is in combat or out of combat. It takes around 1.5 seconds to consume the burger before being able to swap weapons.

It looks like a burger with no sesame seeds on its bun, and inside of it is meat, cheese, tomato, and lettuce. It has the most inhumane looking bite on its side, and somehow always has a bite on it. Nobody knows how Scout even eats this thing.

Tactics

 * Eat it if your hp is lower than 100

Trivia
This is the only weapon in the game that isn't the health kit that has the purpose of giving the user self-heal. Although the stim pistol and booster shot can be used to self-heal as well, that feature was entirely unintentional, and requires a specific circumstance to pull off.
