# Custom Floors

Expand the Gungeon currently adds 3 (but possibly 4?[*citation needed*]) custom floors, each with unique qualities and tilesets.

##### The Jungle

The Jungle is the first of the custom floors that you will encounter in Expand. The jungle is an alternate floor to The Oubliette. The entrance to The Jungle appears on the first floor in a room with Arrowkin and two locked doors. Behind the locked doors is a large tree, which is the entrance to the jungle. The tree can only be opened using fire, you can either use an Item or Gun that shoots fire, or you can use the oil barrel and explosive barrel found within the room to set the tree on fire.
The jungle itself does not have any new enemies, but it does use enemies from the R&G Dept. along with a copious number of Arrowkin, enemies usually not encountered in standard runs. In the jungle there is a crest room, similar to the one in The Oubliette, which is used to access another one of expands floors, Belly of The Beast. The Boss for the jungle is the The Last Human, from the Robot's past, though it is renamed to Com4nd0, and spawns normal enemies as opposed to terminator-like enemies.

##### The Belly

The Belly is the second of the custom floors you encounter in Expand. The Belly is an alternate floor to The Abbey of the True Gun, and its entrance is also very similar. You place the wooden crest(found in the jungle) on an altar similar to the entrance to the Abbey. The boss of this area is the Interdimensional Horror, though it is renamed to the Parasitic Abomination. After defeating said boss there is a room with a guaranteed black chest, and the exit to the area.

##### **Old West**

the Old West is the final floor offered by Expand the Gungeon and requires a Rat Key to enter it in The Hollow, making it both an alternative to both the R&G dept, and a succession to the Resourceful Rat's Lair. The floor is full of puzzles and difficult to find secrets to locate rat keys which can be used to progress through the floor, the floor contains a few too many things to note but a significant part is the 5 gate hallway behind the shop, each gate needing rat keys to open. beyond said gates is a guessing game leading to a rainbow chest, this game requires rat keys, a few rooms of enemies that will earn you rat keys upon completion, and a room where you fight phase 1 of the Resourceful Rat after which he dies and you can destroy his corpse for a rat key, this room also presents an entrance to the Aimless Void. The special bosses in this floor are the Doppelgunner, which is a copy of your current gungeoneer. This boss shoots the same bullets as your current gun, and the Western Bros, which are 3 bosses that get angered when two of them die.

##### ??? ("an alien place")

"An alien place"(not actual name) is a strange floor seemingly only accessible via the **Portable Elevator** item. While it seems to have it's own textures and colour schemes, the floor's enemies and layout are seemingly identical to the Abbey of the True Gun, including the boss, who is [presumably] always the Old King. However, if you kill the old king flawlessly, you will be awarded a **Corrupted Master Round** instead of the regular nothing you get for beating him flawlessly. The only other thing of note is that the floor does not contain Brother Albern.
