The Callisto Protocol’s inventory space is one mechanic that separates it from its spiritual predecessor. The number of items you can carry are limited so any extra ammunition or potentially life saving equipment might be discarded if you don’t have enough room. Read on, and this guide will teach you how to increase your inventory space in The Callisto Protocol.

How to Increase Inventory Space in The Callisto Protocol?

You will automatically increase your inventory space once your reach midway of Chapter 5: Lost where you’ll find the only inventory upgrade in The Callisto Protocol. The item for your inventory space increase will be found on the main path so no need to go looking for it.

You won’t be able to find an inventory space upgrade at least until more than halfway through the game. You can check out our The Callisto Protocol Chapters List to see how many chapters you have to go through until you get the inventory space upgrade. Unfortunately this means that you’ll have to contend with a smaller inventory in the beginning of the game.

Once you find the inventory upgrade, it will double the items you can carry. Where you could originally have six items, you will now have twelve which is more spacious.

Considering how much tougher the enemies will be at the second half of the game, you’re going to need that inventory upgrade. Still even when you can hold a lot more, you should take care to be frugal with ammunition and the likes.
