Welcome to The Callisto Protocol – Combat Guide and Gameplay Playthrough Guide.

This playthrough guide will show you the basic and useful combat mechanics. Are the “tutorials” a little hazy? We describe or attempt to explain the mechanics of combat.

Introduction or Does It Need to Be a Guide?

This guide is intended to be a self-answer, allowing players to crowdsource information about how certain mechanics work (.): Worms and “stomp mutation stopping page”.

Players learn these points easily after hours of playing and trial-and-error combat engagements. However, this is all information I wish I had known before I dived into the game (. I found myself constantly pausing to look up/reread tutorials as I went through the early game prison to figure out what I was doing wrong).

I hope that anyone like me, who hasn’t played it yet, or discerned them on their own (, or has conflicting evidence in), can use this information as a reference.


Dodging can feel a little confusing for new players. It’s clunky, slow, and a little confusing at first. You are hit with dodged attacks and don’t know what’s happening.

1 – To successfully dodge an attack, you must hold A or D in advance. I don’t mean “in advance” for a second. There are no timing windows. You can’t dodge using nonexistent timing windows that you believe may be the reason for any dodged attacks you have. Jacob will still be clipped if you try to dodge an attack as it happens. This behavior is not intentional. You can dodge an attack if you hold A or D before it happens. In my experience, I avoided getting hit by any attacks within the first few hours and continued playing the rest of the game with no problems by doing the above.

2 – Dodge direction doesn’t matter. This common mistake made by new players leads to the following question: “Why did I get hit with an attack that I dodged?” It must have been an error in my dodge. It wasn’t. You didn’t. It was just the “bug” mentioned above. Regardless of the attack direction, it doesn’t matter if you dodge left or right. You can dodge it if you know how to hold the dodge key.


“What’s the point in blocking?” “Why is this a mechanic when I can just dodge?”

1 – You can take damage even if you block. It is better to dodge an attack than to block. Although the damage you take will be minimal, it can still cause significant damage on the hardest difficulty. If you are on the hardest difficulty, upgrading your stun baton will reduce the damage taken when blocking (. However,) is the best option.

2 – If you want to trip an opponent, you must block. You’ll be able to read various tutorials on the main menu if you’re a new player. Many of these explain mechanics that aren’t yet available to you (, but they don’t mention). You can unlock this later by using a block counterattack. This allows you to strike an enemy’s legs right after blocking them and drops them to the floor.

3 – Blocking can damage the projectiles; see the next section.


This section is a placeholder for questions about melee attack mechanics. Although blocking and dodge have been covered, there shouldn’t be any confusion or ambiguity in the melee attack mechanics.


This is a simple explanation of guns. You don’t get ammo drops until you have it (. If you want more ammo to buy weapons, DO NOT purchase weapons other than those you need). However:

“What is this quick swap tutorial?” What is the switching mechanism? I don’t get it.” This tutorial is a complete sham. It explains that you have two “bases” for your weaponry. The one-handed modular weapon platform is the base. The other is for two-handed use. The two-handed one will be available later. The quick swap is when you switch between the one-handed weapon or the two-handed weapon. It does not refer to switching from one gun type to another. One weapon type can be held on each platform at a given time. Quick swapping between them is possible. Jacob takes the weapon type you wish to change from a pistol to a Skunk gun and places the other type on the platform.

This is to clarify for those who, just like me, saw the quick swap tutorial before it was relevant and were baffled by how pressing quick swap did absolutely nothing and how slow it took to change weapons from handgun to skunk guns. This is because you only have one-handed control of half of the game.


1 – Projectiles can’t be dodged. Jacob is not able to dodge projectiles if they are far enough away.

2 – Projectiles should be blocked to avoid any damage. Although it is not as effective as sidestepping, it is often not a luxury (. Jacob will either perform a dodge while being melee attacked by another enemy, which will keep you in place while you perform it, and allow you to be hit with).

3 – You can block the worm leaps, but it seems unreliable. I have done some testing, but it doesn’t work half of the time. I haven’t found a reliable way to deal (with worms. Shooting is not always reliable because you must be able to react, aim, and shoot fast enough to anything small visible on the screen). Comment below if you have any reliable methods to deal with these things to stop their “latching-on” attack. It seems that the worms bypa*s the block half of the time while the other half pop on contact (, which appears to do more damage. I don’t know if this is a kamikaze mechanism, but I can tell if they did.

GRP Mechanics

1 – You can ignore the tutorials for this game. The GRP doesn’t “slowly charge,” which would imply that it slowly recharges over time. Instead, the GRP will completely recharge itself after a certain amount of time. The cooldown starts when you stop using GRP. After that, all your energy is restored. The GRP upgrades reduce this cooldown time. I repeat, the tutorial lies to you.

2 – Energy expenditure varies between low, medium, and high for object enemies, normal enemies, or large enemies. Firing an object takes energy (, depending on the cla*s of object. Holding an object drains the GRP. You can hold an object for a very long period with little energy. A normal enemy will drain energy at an alarming rate. A large enemy can drain energy at a frightening rate and can easily kill your battery with an un-upgraded GRAP. Grab the) tall spitter and throw it as fast you can. You can either shoot the heads of your enemies or pull them in so you can melee/shoot them.

3 – No, you cannot slow down time at any point.

Tentacles/Stopping Mutation

Just shoot the tentacles.

You might say, “There doesn’t even have to be a subsection for this,” I hear you say. And you’d be right, except to refer to the mysterious nonsense that the in-game tutorial refers to:

Stomp on a downed enemy to prevent them from mutating further and attacking again.

What does this all mean? Who knows? It doesn’t seem to work or isn’t feasible. I’ve tried it multiple times. Don’t try or go out of your way to try it. If you see tentacles, kill them. It is a quick kill, even if it isn’t always. You generally have plenty of ammo.
