Special Rooms

The shop is a special room that appears at the end of every world (except for Mechtropolis), meaning it appears every ten rooms. It is a room that has no hostile enemies, unless the player killed several Friendly Droids (in that case, a Shadow may spawn). In the room stands a Friendly Droid behind a counter with four different items on it. The items can be bought for circuits, with their price depending on which world you are currently in. Shops in later worlds sell items for higher prices.

If a shopkeeper is killed, or if multiple Friendly Droids are killed, subsequent shops will not have a Friendly Droid, instead only the helmet of a Friendly Droid will be behind the counter.

All shops have a red button at the furthest left corner (for the Altar shop, it is behind the altar). This button can only be activated by the host and will teleport all players, as well as player corpses, Anti Droid s and certain items to the next world.

Shop 1: Healing Button
This variant of the shop will have a healing button in it. The two left-most items will be weapons, be it melee or ranged. The two right-most items will usually be non-potion consumables, such as healing items or other utilities. Purchasing an item will increase the price of that item by the world number. Berries will not be sold in this shop, except through the Berry Bag, a consumable which gives a random number of random berries. On the left wall (from the perspective facing the counter), a tip/trivia is displayed.

This shop has a brown color scheme.

The shop in World 1 (Sandy Canyon) is guaranteed to be this variant. It will have a healing button and will always sell 2 weapons and 2 consumables.

Shop 2: Cauldron
This variant of the shop will have a cauldron instead of a healing button. The first item from the left is a melee or ranged weapon, while the second item from the left is a potion. The two right-most items will always be berries; Accrue berries and Fervor berries will always be the first berries that the player can buy whenever they enter this shop.

Berries are much cheaper than other items. Unlike other items, whenever a berry is bought, the next berry that you can buy will change to a random berry, along with an increase in price. The cauldron allows players to create potions using the berries they have. The Accrue and Fervor berries are able to create a Potion of Healing. On the left wall (from the perspective facing the counter), a potion's recipe is displayed.

This shop has a gray color scheme.

The shop in World 1 will never have a Cauldron. However, from World 2 onwards, either type of shop could appear.

Shop 3: Ritual Altar
If you've killed multiple Friendly Droids or beat The Darkness, there is a chance of a shop being replaced by a special altar. There are two medkits in the room, one on each side of the back of the altar. The medkits are free to pick up and use. Three items are sold in this shop. The middle item is always a weapon, while the other two items are Sins. Instead of circuits, items in this shop are purchased with the player's health, each item costing 50% of their max HP, and increasing in price every time someone buys an item. The altar will never be encountered if no Friendly Droids are killed. The more Friendly Droids you kill, the higher the chance of encountering the altar. The altar can be encountered multiple times in the same run.

This shop has a dark color scheme. Eerie music also plays when the player encounters this special room.

Trivia

 * The shop is referred to as a "special room" by the game. For example, in the Survivor's second ability, and in the description for the Mobile Phone consumable.
 * The World Number of the shop is the same as the world number of the world the shop is in.
 * Killing the shopkeeper does not affect the price of items on sale.
