The R&G Department is the fourth secret chamber of The Gungeon. Like all secret chambers, the R&G Dept. only appears in Enter the Gungeon. It is a combined office building and laboratory that, based on the name, seems to exist to provide research and development services.

To access the R&G Dept, the player must have a Master Round in their inventory by the time they reach the Hollow. This will cause a guaranteed special room containing the Sell Creep NPC to appear in the Hollow.
If this Sell Creep is given any two items or guns, as well as a Master Round, he will retreat into the darkness and blow open his grate. Jumping down the grate will take the player to the R&G Dept.


RNGDept Layout.png

The R&G Dept. has a fixed layout, meaning it is the same every single time it is entered, unlike every other chamber of the Gungeon with the exception of the Halls of Knowledge. It contains no Shop, no Secret Room, and no Chest rooms, although chests and other pickups can still drop on room clear.
Despite the fixed layout of the chamber, the enemies within the rooms vary greatly between runs, with almost every enemy spawn having a high degree of variance on what it can turn out to be.

The R&G Dept. is also the only chamber to have two different main tilesets, with the lower three rectangle shaped rooms of the floor using a high tech futuristic aesthetic, while the other rooms are styled after an office building.

The boss foyer of this chamber does not contain a corridor to the boss, instead having an interactible ladder which takes the player to the bossroom. Cam Clarke as Agunim is one of only two bosses within the Gungeon to have a unique boss foyer, the other being the High Dragun.

There is no exit elevator on this chamber. After defeating Agunim, the player must throw themselves off the top of the rooftop arena, which will take them to the Forge.


Cam Clarke As...


None of the enemies (including the boss) in the R&G Dept. have official Ammonomicon entries. In addition, all of them exhibit behavior derived from other existing enemies.

Enemy Trivia/Notes

  • The 'Brollet' is a reference to the game 'Broforce', which also contains an enemy wearing a dynamite suicide vest. Broforce is published by Devolver Digital, like Enter the Gungeon.
  • The 'Armored Bullet Kin' releases a green swirl upon death. According to sprite names, this is actually their soul escaping through their armour.
    • This Could be a reference to Dark Souls where upon death you lose souls
  • The 'Pirate Shotgun Kin' does not have hands, unlike most other gundead in the game who handle weapons. Their weapon appears to float.
    • The Pirate Shotgun Kin's corpse also turns red upon death, likely due to it using the corpse sprites of the Red Shotgun Kin, but without applying the necessary shader to maintain the normal colours.
  • The 'Red Bullet Fish' is described as red, but it is clearly blue. This may be a reference to the rhyme 'One fish, two fish, red fish, blue fish'.
  • The Cactus uses the sound effects of the Fungun when it attacks.
  • The 'Angry Necronomicon' may be related in some way to the unused 'Dread Book' enemy.
  • The 'm80 Guy' is based on real m80 fireworks, which are often used by the military for combat simulations.
  • The 'Bullet Gargoyle', based on the appearance of its bullets, may be the ultimate form of Bullat.
  • The 'Cylinder' and 'Red Cylinder' are references to the robotic enemies in Felix the Cat: The Movie, released in 1988.
  • 'KBullets' in real life are a type of armour piercing ammunition used by the German infantry in World War I due to their effectiveness against tanks.
  • No new enemies on this floor have ammonomicon entries, including the boss.
  • The 'Angry Tablet' resembles the Rosetta Stone.

Enemy Gallery


  • The R&G Department is the only floor that uses the art of what would usually be two separate floors. The first floor tileset resembles an office with desks, windows, and water coolers. The second tileset has a futuristic theme with several lights and electric props.
    • These tilesets had been in the files before A Farewell to Arms and were part of a set of unused extra floors, but were not used until the update.
  • Sense of Direction will not work on this floor, possibly due to the fact this floor is not randomly generated and has the same layout every time and possibly because this floor is not left through an elevator.
  • The R&G Department is the only floor that does not contain common enemies such as Bullet Kin, Red Shotgun Kin, Blue Shotgun Kin, and Pinheads. It contains, instead, reskins of these enemies.
  • The music featured on the floor was part of the original soundtrack, with "Office Party Massacre" and "Inter Office Annihilation" being the soundtrack to the first half of the level and "Hulk Melting" and "Hulk Destruct Button" being the soundtrack to the latter half.
  • The name is pronounced RNG, being a pun on "Random Number Generator" referencing the game being a rogue-like and R&D, "Research and Development". It is unconfirmed, however, what the acronym actually stands for, but may possibly stand for "Run & Gun".
    • The former is somewhat ironic, as the R&G Dept. is the only floor that is not randomly generated.
  • Most of the enemies and appearance of the floor reference various cut/unused content from the previous update, with tiles from the unused futuristic floor Phobos and cactus enemies that are referencing the unused West floor.
  • If the player defeats the boss while flying outside of the platform, the player will instantly fall into the next chamber without being able to retrieve the loot.


  • In the room where the player finds the giant manager Bullet Kin, we can see a table with 4 small toys which resemble the 4 main Gungeoneers. They can be seen playing with them when the player enters the room and gets mad if they destroy the table.
  • The fixed layout of this floor is mapped to appear like a gun.
