Cones

Cones are yellow and can be picked up across the map. When holding a cone in your inventory, you can throw it by holding and releasing "R," or you can wear it and become a yellow infected by holding left click. Cones can only be picked up by humans, and since they can be thrown, they are the only projectile weapon in the game besides an alarm gun. Per hit, they do 15 damage & are most useful when your opponent is camping in a puddle.

Advantages: They are a projectile weapon, meaning that it can be thrown instead of being used melee-wise.

Disadvantages: Cones are a bit inaccurate and buggy at sometimes, and only do 15 damage.
