note: this guide may be outdated as of june 2025. if anything changes tell me and i'll update it tout suite.

right click on peripeteia in your steam library and select properties. then add the line "-cheats" (without quotes) to the launch options. it should look like this.

you are now ready to begin cheating. press the pause/break button to go into freecam mode and use the numpad to activate cheats. you can only use cheats while in freecam mode. you may need to turn numlock on for these to work.

• pause/break: freecam / stops time
  
• 1: teleport marie to camera position
  
• 2: refill health
  
• 3: refill energy (also stops energy drain)
  
• 4: spawn the guncube (storage container with all the guns / augs in the game)
  
• 5: spawn polish soldier
  
• 6: spawn enemy
  
• 7: spawn crate (unbreakable)
  
• 8: spawn explosive barrel
  
• 9: change marie's outfit
  
• *: hide / show hud
