How to Install

Important: Back up your existing SaveGames folder first. Steam Cloud also syncs The Callisto Protocol saves, so disable it for the game temporarily or your old progress may be restored.

Download and extract the .zip file to your desktop.

Open your save folder: C:\Users\[Name]\AppData\Local\CallistoProtocol\Saved\SaveGames\

Backup the existing files in that folder by copying them elsewhere.

Copy the downloaded save files into the folder, overwriting the existing ones.

Launch The Callisto Protocol and choose Continue or Load Game.

The AppData folder is hidden by default. Type %LOCALAPPDATA%\CallistoProtocol\Saved\SaveGames into the File Explorer address bar to open it directly.

About The Callisto Protocol

The Callisto Protocol is the 2022 survival horror game from Striking Distance Studios, led by Dead Space co-creator Glen Schofield. In 2320, cargo pilot Jacob Lee crash-lands on Callisto, one of Jupiter's moons, and is thrown into Black Iron Prison just as an outbreak turns the inmates into monstrous biophages.

Combat mixes brutal melee with a stun baton, a handful of firearms and the GRP, a gravity device that can hurl enemies into spikes and machinery. Biophages can mutate mid-fight unless their growing tentacles are shot off, and every resource has to be carefully managed.

Finding every Bio and fully upgrading Jacob's gear takes careful exploration of the prison and the ruins beneath it. This save gives you the finished story and full collection right away, ready for Maximum Security.
