My own Amnesia?

[Romulator]

If your project will not use the HPL2 Engine, you can use the name Amnesia more or less any way you would like.

If using the HPL2 Engine and Amnesia: The Dark Descent to play your custom story / own game, then you're allowed to:

• Create a Custom Story which can be played through Amnesia with the title "Amnesia" with the HPL2 Engine.
  
• Create a full conversion modification using Amnesia's HPL2 Engine tools.
  
• Edit currently available assets*, for use in your project.
  
• Import and use assets* from Amnesia: A Machine For Pigs and or the Penumbra series.

However, you cannot:

• Take assets* from Amnesia and use them outside of the HPL2 engine in other third party game design software.
  
• Release a commercial project, using the HPL2 engine, with the title "Amnesia" using Amnesia's assets*. That is, do not sell your project.
  
• While we cannot stop you, to avoid copyright and intellectual property laws, avoid using files which you do not have permissions to use.
  
• Include the Amnesia.exe file with your release.

The HPL2 Engine can be found here.

* The term assets here refers to files used by Amnesia, including, but not limited to entities, textures, models, sounds and music.
