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.

Pickups are contained within floating bubbles that the player can collide with to collect. When the player leaves the room, any items that are left behind will disappear. The exception to this rule are bubbles with a small lock at their base and reliquary blessings, which will be present in the room after the player returns.

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. This recharge period can be reduced to two rooms if the player has the Battery cartridge. The players rechargeable bomb capacity can also be increased from two 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. It is possible to have a partially charged bomb be kept after you pick up a bomb that puts you at the rechargeable bomb limit, though it cannot be used in its current state and will not charge further until you have used enough bombs to open up a slot.

Damage Up
Damage increases are a rare pickup that players can obtain either by purchase, by locating them in secret rooms, or receive upon defeating a boss. The pickup affects both the player's default weapon and any weapons picked up as a bonus additive to that which they already have.

As the player obtains more damage, the likelihood of finding these pickups lowers.

Crates
Crates can either be found as a reward for clearing a room or within a shortcut. Players can unlock crates by sacrificing a percentage of their weapon's maximum ammo. If they do not possess a weapon, they will be unable to open the crate.

Special Items
Some items found within the depths of the Facility have special purposes that do not necessarily assist the player in their current run.

Seals
After the player has defeated Overlord once, they can begin finding and collecting Seals. When all Seals have been collected, the door leading to Floor 6 will be unlocked, allowing the player to advance their run after defeating Overlord.
