Beyond the stun stick, players will discover and craft several firearms as they advance in Callisto Protocol. Some weapons unlock through the story, while others require locating the right blueprints to craft. This guide explains how to locate weapon blueprints and unlock every weapon available in the game.

How to craft and upgrade weapons
The Callisto Protocol provides five firearm types:
- Single‑shot pistol
- Hunting rifle “Skunk”
- Police shotgun
- Combat gun
- Assault rifle
In the story, the hero gains some weapons automatically, such as the Single‑Shot Pistol and the Police Shotgun. Crafting the others requires finding blueprints. The guide below shows where to locate every drawing.
You can craft a weapon from a blueprint or upgrade gear at a printer. The printer devices appear in the third story chapter and appear at various locations through the remainder of the game.
Weapon upgrades and new gear require Callisto Credits, the in‑game currency. Players can earn credits by exploring locations, collecting loot, and selling valuable items to vendors. This helps stock up on credits for crafting and improvements.
How to obtain the single shot pistol
The initial pistol is the Single Shot Pistol, found during the third chapter of the narrative. When the player meets Elias’s new ally, the mentor hands over a base for which a single‑shot pistol module must be printed.
How to locate the Skunk shotgun blueprint
The shotgun module known as “Skunk” is mounted on the weapon’s base. This means players cannot switch between the single‑shot pistol and the shotgun without swapping modules. To change, swap the module in the weapon’s base.
The blueprint for this weapon appears in the third chapter, but it can also be found in the fourth chapter if missed earlier.
Finding the Skunk shotgun blueprint in the Consequences chapter
Towards the chapter’s end, players reach a large, multi‑sectioned area. There, a cocoon parasite attack begins. At the start, a lever with a fuse is visible. The device itself sits near the exit end of the area and is crucial for progression.
After picking up the fuse, return briefly to insert it into the device next to the grille leading to the magazine. Proceed to the next room via the vent and locate the blueprint.
Finding the Skunk shotgun blueprint in the residential dome chapter
If the blueprint wasn’t found in the previous chapter, it can be found here. The location is the oxygen purification station in the residential dome.
Enter the building and turn left. Take the hallway to a dead end with a small crawl hole near the boxes, where a blueprint lies on the right side of the crates.
Weapon characteristics
The shotgun serves solid damage at close range and works well for finishing off enemies when aiming carefully. Its primary limitation is a small ammo pool, with only two shells per reserve, which requires frequent reloading in tight situations.
The shell uses its own cartridge type, added to a separate inventory slot when collected, which can reduce overall carrying capacity.
Upgrading this weapon is not always recommended, because a more powerful option arrives later: the police rifle. In early playthroughs, this weapon is often essential for players attempting higher difficulty levels.
How to obtain the police shotgun
The Police Shotgun becomes available in the fifth chapter when the protagonist encounters Dani in the hangar for a second time. After clearing enemies on the first floor and hacking an electrical panel, the weapon can be acquired.
Characteristics
The Police Shotgun delivers high damage and excels at handling large groups of infected, especially in enclosed spaces. It is wise to upgrade it fully and unlock the alternate fire as the game progresses, which further enhances its power and utility.
How to find a combat pistol blueprint
A blueprint for the Combat Pistol is found in the sixth chapter. When Jacob is separated from Dani and moves through the underground tunnels, he should head to the first upgrade device available in that area. A ladder nearby leads to a sleeping undead, making the route clear.
In front of the printer room, a small chamber sits behind a grille. The blueprint rests on a table among various cabinets. If the sleeping specter has been encountered, ascend the stairs to find it.
Characteristics
There is some debate about why two pistols were added. The Combat Pistol offers a faster rate of fire and separate ammo storage, but a fully upgraded single‑shot pistol with an alternate fire mode can rival its performance. Creating and upgrading it also costs extra Callisto Credits.
How to locate the assault rifle blueprint
The final weapon obtainable is the assault rifle. The blueprint appears in the seventh chapter, inside the colonists’ settlement.
Upon reaching the colony, players should first locate an elevator access card. The card sits on a high level, next to the automaton blueprint. Climb and inspect the distant containers on the right. A blueprint hangs in the restroom above the sinks.
Characteristics
By default, the rifle fires three rounds. The damage output is modest, which makes one question its late addition. Even fully upgraded, it may struggle to take down tougher foes quickly. It remains useful for precise shots and boss encounters, especially when aiming strategically.
Like pistols, the assault rifle uses replaceable modules mounted on the gun base, so switching it to a shotgun configuration is not straightforward.
