The Umbrella is a common melee Weapon that can be found in most scavenging locations. Umbrella Shops will naturally contain a large number of them.

The umbrella has low power for the cooldown but it does provide a decent amount of knockback. The umbrella is useful for keeping zombies away if not killing them outright.

If the party has an umbrella certain driving events relating to weather will reference it, it won't impact the outcome however.
