Mortal Sin Save Scum Guide – How to Save & Reload (PC)

Mortal Sin is a brutally challenging first-person roguelike where death means losing all progress for your current run. However, like many difficult PC games, there is a method to create backup saves—often called “save scumming” or “save-loading (SL).” This guide provides a clear, step-by-step method to backup and restore your save file, giving you a second chance after an untimely death.

This method manipulates game files and is not an intended game mechanic. Use it at your own discretion. It can diminish the intended roguelike challenge but is useful for practicing later stages or avoiding frustration.

Step-by-Step: How to Save-Load in Mortal Sin

Before You Start: Locate Your Save File

1. Navigate to the following folder on your PC:
   C:\Users\[YOUR-USERNAME]\AppData\LocalLow\Doronik Games\Mortal Sin
   • Tip: You can quickly access this by pressing Windows Key + R, typing %appdata%, and then going back one folder to enter LocalLow.
2. Here, you will find the crucial save file: MortalSin.sav.

The Save-Load Procedure

Step 1: Create a Backup (Before a Risky Encounter)

1. Return to the Hall. The game only saves when you are in the central hub. You cannot save mid-run.
2. Exit the game completely.
3. Locate the MortalSin.sav file.
4. Create a backup copy of this file. You can simply copy and paste it in the same folder and rename it to something like MortalSin_BACKUP.sav.

Step 2: Restore Your Backup (After You Die)

1. If you die during a run, DO NOT CLICK ANYTHING ON THE DEATH SCREEN.
2. Immediately force-close the game by pressing Alt + F4 on your keyboard. This prevents the game from overwriting your save file with the “dead” state.
3. Reopen the file directory (C:\Users...\Mortal Sin).
4. Delete the current MortalSin.sav file and the eventcache file if it exists.
5. Rename your MortalSin_BACKUP.sav file to MortalSin.sav.
6. Launch the game. You will be loaded back into the Hall, ready to start a new run from your saved point.

Why This Works

The game only writes your progress to the save file upon returning to the Hall or upon a complete game over where you accept death. By force-quitting before the game can save your defeat and restoring a clean save file, you effectively rewind time to your last safe point.

Pro Tips & Warnings

• Consistency: Always make a new backup in the Hall before starting a new run. Your old backup becomes useless once you start a new one.
• Backup Management: For extra safety, you can create multiple backups for different progression points (e.g., Backup_Run1.sav, Backup_Run2.sav).
• The Intended Experience: Remember that this bypasses the core roguelike loop of learning from failure. Consider using this tool sparingly to avoid diminishing your sense of accomplishment.
