When enabled, your operatives will die permanently in-game after taking lethal damage, instead of being unavailable for a short period of time.
The game ends if all your operatives are killed.
You can enable Permadeath when starting a new game.
There are two Permadeath options: Standard and Ironman.
Standard Permadeath can be disabled at any point during your playthrough. You will not be able to enable it again for the same playthrough.
Ironman Permadeath cannot be disabled during your playthrough.
