The Empty Soda Can is a commonly found trash item. It can be thrown to create a noisy distraction for zombies. When thrown at players, it can distort their view and disorient them. It can also be used to smash windows, such as at the front of hospitals, and in large enough quantities (4+) they can be used to kill zombies or players.
When throwing this at destructible glass, it is recommended to keep a fairly large distance as it can commonly cause temporary deafness and blurred vision to anybody too close. The effect on zombies is unknown and requires testing.
