The R&G Department is a secret chamber that was added in the A Farewell to Arms Update.
Unlike other floors, the R&G Department has a fixed layout; however, the enemies in each room may vary slightly from run to run.
Also unlike other floors, there is no elevator at all. The player has to jump inside one of the pits found around the boss room to proceed to the next one, effectively jumping out of the R&G Dept. building itself. The player will, however, come through an elevator when entering the Forge even though no elevator can be seen in the transition to it.
It can be accessed by giving the Sell Creep one Master Round and any other 2 items or guns (including Junk) in a special room in the Hollow. This room is always available if you enter The Hollow with at least one Master Round. After giving him enough items or guns, he will break the grate, letting the player down to the next floor.
- If spawned in the Shop, items that are not guns will bounce off the grate unless you are standing directly on it. It is possible for a Sell Creep to show up twice in the Hollow, both once in his own generated room and in the Shop.
- If you teleport away from the Sell Creep during the explosion of the grate, upon returning, the grate will appear to be untouched and the Sell Creep will not show up anymore.
This is the layout of the R&G Department:
The three rectangular rooms at the bottom have a futuristic tileset. The others are offices.
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.
|Office Bullet||Office||20||Behaves identically to the Bullet Kin.|
|Office Bullette||Office||20||Has pitched-up voice clips.
Behaves identically to the Bullet Kin.
|Western Bullet Kin||Office||22.5||Behaves identically to the Bullet Kin.|
|Pirate Bullet Kin||Office||15||Behaves identically to the Bullet Kin.|
|Bullet Fish||Futuristic||15||Behaves identically to the Bullet Kin.|
|Red Bullet Fish||Futuristic||15||Behaves identically to the Bullet Kin.|
|Candle Guy||Office||15||Behaves identically to the Bullet Kin, aside from its bullets being visually on fire.
While it appears to hover visually, it is not actually capable of flight.
|Brollet||Office||15||Shoots like a normal bullet kin, but will explode when killed or when the player comes too close.|
|Armored Bullet Kin||Office||25||Walks sluggishly towards the player, occasionally firing an extremely slow pointy bullet.|
|Pirate Shotgun Kin||Office||30||Fires a five-shot spread of bullets that are slightly larger than those of an ordinary Shotgun Kin.
Wields Old Goldie.
|Western Shotgun Kin||Office||40||Attacks similarly to a Red Shotgun Kin.
On death, it will release a burst of bullets identical to the on-death attack of the Veteran Shotgun Kin.
Amidst this veteran-style blast, two bonus gigantic cannonballs will also be launched in the direction of the player.
|Musket Ball Guy||Office||12||Rolls towards the player, charging up to fire itself at them, very similarly to a Tazie.
Only deals contact damage while firing. Harmless while rolling.
|Cactus||Office||30||Walks towards the player, releasing rings of spiky bullets around its body.|
|Parrot||Office||12||Behaves identically to the Gigi.|
|Snake||Office||30||Attacks identically to the Veteran Shotgun Kin, except without the burst of bullets upon death.|
|Angry Necronomicon||Office||35||Can fire letter based attacks from the Bookllet, spinning shape attacks from the Apprentice Gunjurer, or random bullet spreads similar to the Gat.
Its bullets are shaped like the number '6'.
|Angry Tablet||Office||25||Behaves identically to the regular Bookllet, aside from its bullets being shaped like spinning triangles.|
|m80 Guy||Office & Futuristic||10||Runs towards the player, bursting into a line of colourful firework explosions upon getting within range.
Highly similar to a Nitra, but with a longer explosion chain.
|Confirmed||Office & Futuristic||45||Slowly walks towards the player, periodically firing four slithering lines of bullets. Is pretty rare to see on the floor.|
|Fridge Maiden||Office||60||Behaves identically to the Lead Maiden, aside from its bullets being shaped like cheese.|
|Bullet Gargoyle||Office & Futuristic||45||Behaves identically to the Cubulon, aside from its bullets being shaped like Bullats mid-flight.|
|Bullet Mech||Futuristic||60||Lumbers towards the player, periodically pausing to jump twice in a row.
On the first jump, it releases a diamond-shaped blast of bullets similar to a Cubulon's attack. On the second jump it releases a more circular ring of 12 bullets.
|Cylinder||Futuristic||15||Drifts towards the player, firing semi-random spreads of triangle shaped bullets similarly to a Gat.
Capable of flight.
|Red Cylinder||Futuristic||15||Identical to the regular Cylinder, except its bullets take on a more atomic appearance.|
|KBullet||Futuristic||20||Behaves identically to a Tombstoner.|
|Kalibullet||Futuristic||20||Fires five bullets in a spray, similarly to a Skullet.|
|Bullet Titan||Futuristic||80||Fires large, slow-moving bullets in spreads of fire.
Wields the unused Big Gun.
|Bullet Boss||Office||100||Fires large bullets in three-way spreads, in bursts of three.
Will occasionally fire with predictive aim, taking the player's movement into account.
Also wields the Big Gun.
|Bullet Titaness||Office||80||Behaves identically to the Bullet Boss.|
- 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.
- 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.
- 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.
