Rooms

Each floor consists of an interconnected series of rooms. They are shown as squares on the map; lit squares are rooms that have been explored, while darker squares are unexplored. The player can teleport between explored rooms by opening their map and selecting the room to which they wish to travel.

Most rooms consist of enemies and traps. When the player enters, all exits will lock and, under most circumstances, the player will be forced to defeat all enemies in the room in order to leave. Upon defeating the enemies, the doors will unlock and there is a chance that a pickup will generate as a reward.

In addition to these average rooms, there are a variety of special rooms.

Special Rooms
Special rooms are indicated via different icons on the map and have special items or special effects depending on the type of room.

Boss Room
The room in which the floor boss is sealed. Upon defeating all mini-bosses on the floor, the seal on the north end of the room can be broken and the boss can be fought. Once the boss is defeated, the player can proceed through the north exit to proceed to the next floor (unless facing the final boss of a run).

Boss rooms are indicated on the map via an icon of a skull.

Breach Room
Breach rooms are indentified on the map via their red color. They can be accessed after destroying the breachstone somewhere on the floor.

Challenger Room
Challenger rooms are rooms designed to be more challenging than their conventional counterparts. Greater numbers of difficult enemies are typically found in these rooms, and the amount of bullets fired by each enemy is slightly higher than normal.

Players are guaranteed a pickup upon clearing the room.

Digging Room
Digging rooms are identified on the map via their yellow color.

Mini-Boss Room
In the miniboss room you'll be faced with a miniboss that has a seal around them, if you defeat the miniboss the boss room will have one less seal. The rewards for defeating a miniboss are always the same:

You may choose between:

• Restore 20% of your weapon's ammo

or

• 1 HP or HP Part (if you have full health)

The icon of the room looks like a black square with borders and a pixel in the top right corner of the icon.

Secret Room
Secret rooms are identified on the map via their yellow color and a question mark icon. They are not marked on the map when in a room adjacent to them and, most of the time, must be revealed by using a bomb.

Secret rooms always contain some sort of pickup or weapon, though the quality is variable.

Shop
In shops, players can trade debris or sometimes HP in exchange for a variety of possible pickups. There are several shop types, but the most common will provide the player with three choices consisting of pickups (varying in quality) or weapons.

Shops are indicated on the map via an icon of an exclamation point.

Shortcut
Shortcuts are rooms that can be opened up by using bombs. Unlike secret rooms, these are displayed on the map before being opened.

The value of what can be found inside of these rooms varies greatly, ranging from enemies to powerful upgrades.

Shortcuts are identified on the map as a hollowed-out version of a normal room, missing the green coloring in their center.

Deactivated Machine
A deactivated machine is identified on the map via an icon resembling the machine itself (Microcore).

Trader Room
Trader rooms are identified on the map via an icon resembling the mask of the Trader NPC. The Trader himself, found inside these rooms, will offer maximum ammo, health, damage, or a cartridge in exchange for maximum ammo, health, or damage.

When the player exits the room after declining his trade offer, he may no longer be found within the room upon re-entry.

Reliquary
Reliquaries contain two shrines, resembling Council members, that offer a choice between two blessings based on which shrines are present in the room. Blessings grant the player a bonus effect that is permanent unless replaced by another blessing later on. Blessings do not disappear if the player leaves the room.

Each blessing is named after its representative Council member's preferred magical type.

Upgrade Terminal
Upgrade Terminals are identified on the map via a plus sign. Upon entering the terminal in the center of the room, a player can choose from one of three upgrades. If the player has the Plug cartridge and successfully hacks the terminal before entering, they will receive an additional upgrade option upon entering.

Vault
Vaults are identified map via a keyhole icon. When a vault is present on the floor, a player will be able to find a key to unlock its door and gain entry. Within, players are guaranteed to find pickups, weapons, or both. The quality of the vaults contents ranges, but they tend to be of a relatively high quality.
