Arsenal Labs

**Arsenal Labs** are various laboratory structures that generate in various biomes around the world. All laboratory structures contain Aged Security, Security Chests, along with other functional furniture that allow the creation and charge of several weapons. The labs are defended by Lab Turrets, which fire lasers at nearby players. While in a lab, the player's Stamina  will decrease by 1 point every 10 seconds. With the  addon enabled, the Lab Hologram Projectors found within the Bio-center Labs can be tampered with using the Bloody Vein, which will summon the Cyber Draedon mini boss.

Each of the Bio-center Labs can be located easily with their respective Seeking Mechanisms.

### Abandoned Workshop

The abandoned workshop is a small, dual-level structure comprised of Rusty Plating and Pipes. The upper level expands outward and contains some storage crates and boxes. The top platform holds an aged security chest. The lower level of the workshop contains two powered off Draedon Fuel Factories. It is the smallest of the Arsenal Labs, and multiple can spawn in a single world.

### Abandoned Research Facility

The abandoned research facility is a large structure featuring a dome shape comprised of laboratory plating. The structure is defended by two lab turrets on the ground. The upper platform holds an aged security chest, and two Draedon's Charging Station to the left and right of the chest. The ground floor consists of various crates and boxes, and some defunct laboratory equipment. Multiple abandoned research facilities can spawn in a single world.

## Bio-center Labs

These Arsenal Labs are unique and only spawn in their respective biomes.

### Jungle Bio-center Lab

The Jungle Bio-center lab is located randomly in the Underground Jungle or Glowing Mushroom biome, and features a core of Plagueplate, with two smaller vertical shafts on the left and right of it. Above the core, there are two large robotic arms with an empty platform, with some laboratory equipment above it. Below this platform are four Plagued 'Bed's, acting as test tubes, with piping leading up to a large empty liquid tank. A hologram projector can be found to the left of this tank, and security chests, factories, and chargers on the same level as the Plague Plate Beds. The right side of the structure has been completely blown away and contains a massive empty crater.

 The Plaguebringer Goliath boss is fought in this lab by inserting the Abombination into any of the lab's Plagued 'Bed's. In the event that the lab spawns in the Glowing Mushroom biome, The Plaguebringer Goliath will take on a new form that increases her aggression and allows her to drop the Psy Rod.

This Bio-center lab can be located with the Green Seeking Mechanism.

### Ice Bio-center Lab

The Ice Bio-center lab is located randomly in the Ice biome, and features a core of Elumplate with two vertical shafts on the left and right, leading to pyramid-shaped structures on the top and bottom of the core. The top pyramid contains various lab equipment, charging stations, factories, security chests, a hologram projector, as well as four lab turrets. The bottom pyramid contains an unlocked Frozen Chest with various ice loot.

This Bio-center lab can be located with the Yellow Seeking Mechanism.

### Space Bio-center Lab

The Space Bio-center lab houses a core of Cinderplate, and is located in the main Planetoid of a world, above the center of the map. It is the smallest of the bio-center labs and only features a core and 2 small branching hallways to the left and right of it. Two lab turrets are located above the Cinderplate core.

This Bio-center lab can be located with the Purple Seeking Mechanism.

### Sunken Sea Bio-center Lab

The Sunken Sea Lab is located toward the bottom of the Sunken Sea and features a core of Navyplate with two stairwells branching from the left and right. The stairwell on the right will lead to an observation deck, guarded by a turret, overlooking a large sea prism in a machine. The stairwell on the left will lead upward to a small aquarium filled with water and some sunken sea debris and tiles. In this section, there is various lab equipment and a hologram projector on top of the aquarium.

This Bio-center lab can be located with the Cyan Seeking Mechanism.

### Underworld Bio-center Lab

The Underworld Bio-center lab is located on the far-right side of the Underworld and is the largest of the Bio-center labs. It features a core of Chaosplate, and a surrounding oval-shaped structure containing various pipes, lab machines, a Hellforge and lead anvil, as well as the other content contained in each bio-center lab. One of the hell lab's security chests contains the Murasama, a powerful Post-Yharon sword. The structure contains two massive lava tanks on each side, with branching pipes reaching up into hell's lava lakes. The structure is defended by two lab turrets on its upper floor and two on the bottom floor, one on each side

This Bio-center lab can be located with the Red Seeking Mechanism.

### Onyx Bio-center Lab

The **Onyx Bio-center** is a lab that contains the Onyx Excavator Key, located in front of the lab. This lab can be located using an Onyx Seeking Mechanism.

The boss Onyx Kinsman can be fought here, so long as an Earth Elemental has been defeated once, the player has an accessory which summons an elemental of any kind, and has not interacted with the Onyx Excavator beforehand. If you meet these, then interacting with the Onyx Excavator will summon the Onyx Kinsman.

## Notes

* Despite the Ice Bio-center Lab having an Ice Chest, it does not contain a Staff of the Frost Hydra.

## Tips

* Turrets can easily be removed by placing blocks in the direction they are firing and slowly approaching them, before mining them through the solid blocks.

## Trivia

* The theme heard while inside any of the Bio-center Labs is **Engineer's Sanctum*****,*** which was composed by the artist Heart Plus Up! It is one of the few themes that was originally created for the Vanilla Calamity Mod Music mod, before being added into the Calamity Mod proper.
* Previously, certain structures would contain a second type of turret known as Field Generators.
* The Ice Bio-center Lab, Space Bio-center Lab, and Underworld Bio-center Lab replaced the Ice Tomb, Main Planetoid Lab, and Underworld Shrine, respectively.
* The labs appear to be for running various experiments, each specific to the lab they take place in. The ice lab is testing the machinery in low/subzero temperatures, the jungle lab is testing the effects of The Plague, the space lab is testing the machinery/infrastructure in low orbit, the underworld lab might just be a solitary workshop for developing the Murasama, and the sunken sea lab might be testing solitary evolution (a concept which confused Draedon, as shown in the log for the sunken sea)
