A throwable is an item that can be picked up normally and when left or right clicked is thrown, which differentiates it from other items. Most items either are throwables or can become throwables, with the only exception being the Katana. A gun will become a throwable after running out of ammunition and then clicking. A melee weapon will become a throwable after clicking about 3 times, excepting the Katana. Throwables, when thrown, will shatter on impact, stunning nearby enemies and breaking items and glass that it hits.
