The Bowgun is made available for purchase in the Rewards menu after completing all of the main campaign episodes on Normal difficulty or higher. It is listed under the name "Bonus Weapon: The Assassin's Choice" before unlocking and later simply "Bonus Weapon: Bowgun" for 10000 BP. It can be equipped from the workbenches in both Claire and Barry's campaign. Like all bonus weapons, the player will only get a C rank for the chapter if used.
