Some of your weapons must be made according to The Callisto Protocol. However, you must first locate the schematics. Let’s find the answer of How to Locate All Gun Schematics in the Callisto Protocol.
The Callisto Protocol has a lot of battles because there are so many monsters to fight throughout the adventure. You enter the prison with no means of defence but quickly acquire a number of weapons as you progress.
However, the Stun Baton, Hand Cannon, and Riot Gun aren’t the only lethal weapons you can get your hands on. A few schematics from the game can also be used in the reforge to create new weapons. It’s worth looking for the schematics because you can make some good guns this way. You can find them here.
How To Locate All Gun Schematics in The Callisto Protocol
Location of Skunk Gun Schematic (Chapter 3)

The Skunk Gun schematic is the first one you can find, and it can be found in the chapter titled “Aftermath.”
There is a scene where you are on top of an elevator and Elias tries to lower it gradually halfway through this chapter. You enter the area where the Skunk Gun Schematic is concealed right after the lift crashes to the ground.
As you proceed, you might notice a fuse missing from a box to your right. To get to the location with the schematic, you must give it one. So, turn left and take the natural route around, eliminating any enemies that stand in your way.

Go to the locked workshop in the corner once everyone is dead. A gate fuse is located on the floor in front of the door. Pick it up and place it in the earlier fuse box.

You now have access to the tiny space to your right. There is a vent inside, through which you must stoop.
Turn left when you cross over to a workbench where the schematic is located.

Location of the Tactical Pistol Schematic (Chapter 6)

You first meet the dangerous blind enemies in the Below chapter. Don’t make a sound is written on a broken wall in the game, making it abundantly clear how to handle them.
You know you’re close to where the Tactical Pistol Schematic is waiting when you see this message. Quietly turn left from there and then take the next right.

This places you in a region filled with enemies and covered in spikes. Right after ascending the stairs on the opposite side of the room. There will be some enemies attacking you here, so vault over the metal beam and go through the opening.

Enter the room on the right after that. There are many supplies in this room, but the schematic should be on the table.
Location of Assault Rifle Schematic (Chapter 7)

Near the start of the Colony chapter is where you can find the Assault Rifle’s schematic. More specifically, the first enemies of chapter seven are found in the small shanty town.
On the right side of the space leading to Midtown, there is a ladder.

When you reach the top, pass through the general store and turn left as you leave.

There will be a bathroom in front of you. Pick up the schematic above the sink once you’re inside.
Because of this, enemies will attack you right away. However, because you will have discovered the final schematic, you will have the last laugh.
Location of Stun baton Schematic
Unless you count the ineffective crowbar, your first real weapon in The Callisto Protocol is the stun baton. You will enter a cutscene where Jacob takes the stun baton from the corpse of a prison guard once you crawl through the vent and get to the security lock-up.
Location of Hand cannon Schematic
The B-155 hand cannon or pistol is diminutive but surprisingly powerful. It can carry you comfortably through a significant portion of the game with the right upgrades. The schematic will be thrown by Elias when you meet him at the watchtower in “Outbreak,” and he’ll signal for you to print it at the Reforge, so thankfully there’s no way to miss it.
Location of GRP Schematic

The GRP reappears in “Aftermath,” and it’s yet another crucial weapon that shouldn’t be overlooked. You encounter this kinetic glove as you move through the hospital. As you enter the examination room, a dead prison guard is placed on a gurney, and Jacob will take away his GRP during a cutscene.
Location of Riot gun Schematic

Dani gives you the Riot Gun, a two-handed shotgun made for riot control, after you help her defeat the biophage in the garage at the start of “Lost.” This is a blessing because it eliminates the need for you to carry a weapon schematic to a reforger, and it will be useful when you’re trying to figure out how to save the trapped worker in The Callisto Protocol right after this cutscene.
Conclusion of How to Locate All Gun Schematics in the Callisto Protocol
As you battle through Black Iron prison, having a full arsenal of The Callisto Protocol weapons will add some much-needed variety to your combat. While some are given to you during the narrative, others come in the form of schematics for various weapons, and it is simple to miss them.
To help you defeat the Callisto Protocol final boss with all the necessary firepower in one of the best horror games of 2022, we have tracked down the locations of all of its weapons. Unfortunately, weapon schematics require an inventory slot just like health injectors and battery packs—at least until you can find a reforger that can print them. The receiver is now visible in your arsenal rather than your items. It’s also important to note that the reforger will charge you for their services, so be sure to save enough credits to print them.
