Bosses are strong enemies found at the end of every floor in The Gungeon. Defeating a boss allows the player to advance to the next floor.
Upon being killed, bosses drop a weapon or item of random quality, several Hegemony Credits, and one to three pickups such as hearts, ammo, or keys. Bosses will always drop a gun if the player has not yet picked up a gun on the current floor. If a boss from one of the five main floors is defeated without taking damage, they will drop a Master Round as well.
