Before Fortoresse became it's own game with it's own website (, it was available to play (and still is!) as Forteresse at Extinction (


Fridge that needs to be protected / destroyed.

The biggest difference (for many) is that it's completely in french. However, there are other differences such as:

  • It's not part of the "Transformice framework", and thus has a different UI and "physics".
  • Different controls
  • Official maps have only one game mode - "destroy the fridge". Each Fridge has 40 hp.
    • Custom maps may have other modes
  • Not everything can be shot / environment isn't blocks.
  • Your conj is solid even for teammates.
  • You have to hold down the mouse button to spawn conj.
  • You can shoot a different type of ammo (Ham bombs Bomb-extinction.png).
    • Bombs don't damage fridges.
  • The faster you fire, the more inaccurate your aim becomes (shown as a circle getting larger, showing just how much the inaccuracy is increasing).
  • The numbers next to a players name represent the kill count and damage to the fridge.
  • Moving during a reload will interrupt it.


You can choose between 4 different skins in the settings menu. There also a 5th skin in the game, although it can only be worn by entering in the /jack command before entering a Fortoresse room.
