Pickups

There are a variety of items that the player can find throughout the Facility. Most commonly, players will find debris, health, weapon ammunition, and bombs. Less frequently, for instance, maximum health upgrades and damage increases can be found.

Various factors play into the frequency and types of pickups the player will find including the possession of certain upgrades and cartridges.

Debris
Debris is the currency used to buy goods at shops. The amount of debris dropped by enemies varies and is influenced by the players current multiplier. Debris can also be obtained by scrapping weapons, picking up pickups past their maximum allowed amount, and by obtaining items that turn into debris upon pickup.

Health
Health pickups come in a variety of forms ranging from health parts to maximum health increases.

Ammo
Ammo pickups either refill the player's weapon ammunition or increase the player's maximum ammo capacity.

Bombs
Bombs are used to destroy all bullets on-screen or to blow open walls that lead to shortcuts or secrets. By default, the player starts the game with two rechargeable bombs. When one of these bombs is used, it can be recharged by clearing enemies from three rooms. The players rechargeable bomb capacity can be increased to three if they obtain the Extra Pow upgrade. At any point, the player can hold up to six bombs total.

In addition to normal bombs, there are several special bombs that produce an additional effect depending on their type.

The player's current bombs are displayed in the top-left region of the HUD. Normal bombs are indicated via the color yellow, and each special bomb has a different color associated with it. When a rechargeable bomb has been used and the player's current bomb count is less than their total rechargeable bomb count, an outline will be left in its place. This icon will gradually fill as the player clears rooms of enemies, until the bomb is recharged.

Map
Maps reveal the entire floor, including secrets. They can be found in certain shops or as a reward for defeating the Big Bat.

Key
Keys only appear if the floor has a Vault generated on it. Keys can be found as a reward for clearing a room, within Weapon Chambers, within Secret Rooms, or for purchase in certain shops. When a key is collected, an icon appears below the player's HP display.

Traveling to the next floor without using the key will result in it being salvaged as debris. The value of the key is dependent on the floor in which it is salvaged.

Keyword Stones
When picked up, if the player possesses a weapon, three keywords will appear and the player may choose one. If the player does not currently possess a weapon, the keyword stone will turn to debris.

Cartridges
Cartridges act similar to upgrades in that they give the player a permanent, normally significant effect upon pickup. They are a fairly rare item but can be found in several different places (Shops, Secret Rooms, Crates, etc), excluding as a reward for clearing a normal room.
