The Callisto Protocol Guide: Walkthrough, Tips and Tricks, and All Collectibles

The Callisto Protocol is a new survival horror game for PS5, PS4 and Xbox Series X|S, Xbox One, and PC. While it might be a new IP, the game from Striking Distance Studios is pretty heavily inspired by Dead Space. Our The Callisto Protocol walkthrough, which documents all collectibles, will guide you through all of the chapters in the title, sharing strategies for combat encounters and letting you know what to do next. In our The Callisto Protocol PS5 review, we awarded the game a 7/10 and called it a "consistently good game".

As part of our The Callisto Protocol guide, we'll also reveal a The Callisto Protocol Trophy guide and a selection of tips and tricks for beginners. While this guide is based on the PS5, PS4 versions, Xbox Series X|S, Xbox One, and PC players shall find their experiences to be virtually the same as PlayStation users and, therefore, can use this guide for help too.

The first part of our The Callisto Protocol guide is a The Callisto Protocol walkthrough, which explains how to complete all 8 chapters and where to find all collectibles within them. We'll document where to head next and how to handle any enemy encounters.

For the next part of our The Callisto Protocol guide, we're going to list all collectibles. There are 2 collectible types for a total of 43 collectibles. Our checklists will help you find them all, with pictures and descriptions to explain their exact locations. The collectible types are as follows:
• Audio Logs: Small devices you can pick up that trigger a personal conversation in your inventory. Generally found just off the main path in side rooms and crevices.
• Implant Bios: Data took off specific bodies that allow you to access new parts of the Black Iron Prison. You'll interact with the C.O.R.E. Device on the back of their neck, indicated by a green symbol above the body.

All collectible types can be tracked on the inventory screen by selecting the Data-Bios tab. Listed below are checklists for all collectibles, revealing when and where you can find them.

In the third part of our The Callisto Protocol guide, we'll cover the equipment you can both acquire and upgrade. We will first focus on weapon locations and then reveal some of the best upgrades you should buy first from Reforge stations.

The Callisto Protocol Guide: Tips and Tricks for Beginners

In the final section of our The Callisto Protocol guide, we're going to provide some universal tips and tricks for beginners. These will make sure you're fully prepared for Jacob Lee's attempted escape of Black Iron Prison and dealing with its inhabitants. While the game does have difficulty settings, these tips will help you get the most out of it.

The Callisto Protocol brings back the classic stomp ability from Dead Space. Whenever you kill an enemy, always remember to stomp on them. They always drop an item including ammo, health, and Callisto Credits. The latter allows you to purchase upgrades for your weapons, so the more of them you have the better. Then, with more bullets and health, you have a much better chance of surviving.

Don't Just Aim for the Head

Enemies in The Callisto Protocol don't die when you take their head off; they keep going. Instead, focus on knocking their limbs off, particularly their legs, to immobilize them. This makes them much easier to kill. Removing the head will always help, but it's not going to immediately down an enemy like it would if they were human.

The GRP Gives You Easy Kills

The GRP allows you to pick up enemies and throw them wherever you want. Since bullets are somewhat limited, make it the first means of attack especially if there's active machinery or spikes on the wall nearby. Grab an enemy and throw it at them and it'll be killed immediately, saving you ammo for other foes.

The Stun Baton is just as important as the weapons you accrue for combat, so don't forget about it once you get a few guns. Some perks allow you to perform a sweep attack after a block, while others boost your damage. Particularly during one on one engagements, you should probably be opting for the Stun Baton; making sure it's at its best is vital.

Reforge stations aren't just for upgrading weapons. If you cycle between the options, you can buy ammo for all your guns for incredibly cheap. Since you don't find a lot of bullets out in the open, we recommend stocking up with any spare Callisto Credits you have left over after buying upgrades.

That concludes our The Callisto Protocol guide. We hope you found this resource useful! If you have any further tips or hints to share, feel free to post them in the comments below.
