How to Play the Custom and Shell Shock Halloween Mode in Amnesia: The Bunker

Frictional Games have surprised us by giving us two new game modes for Amnesia: The Bunker, just in time for Halloween. In this article, I will show you how to unlock and play the Shell Shock Halloween Mode, as well as the Custom Mode.

How to Unlock Shell Shock and Custom Game Mode in Amnesia: The Bunker

Shell Shock and Custom Game Modes in Amnesia: The Bunker are unlocked by first completing Amnesia: The Bunker at any game difficulty. However, if you do not want to play the entire story mode first, or you lost your save file, you can see the shortcut for unlocking it in the last section of the article.

What is Shell Shock Mode in Amnesia: The Bunker?

Shell Shock mode is a hardcore-difficulty mode that will completely shake up your playthrough. Additional difficulties and obstacles will be added, and some essential items will be randomized, forcing you to throw all your knowledge about the item locations out of the window. The Safe Room may no longer be safe. Saving your game may not be available anymore.
