Clowns are a special NPC in POSTAL Redux.
POSTAL Redux Edit
Clowns were introduced in the Carnival level of Redux where they serve as both hostiles and civilian npcs. They are armed with various balloon weaponry which hold the same properties as the normal weapons.
When one plays the Co-op mode, CPU controlled Clowns (bots) can be added to assist the player until another player shows up or until there are four players in game. Much like their hostile counterparts, they carry balloon weaponry.
