Mods

Enhanced Shaders - Improves shaders, such as bloom and SSAO, making them more realistic.
Improved lantern - Adds a more realistic and detailed lantern model. Also incorporates the Dynamic shadows from lantern mod.
Darkness Light - Makes the dark darker, thus more realistic and harder.
New Insanity Ear Ring - Makes the tinnitus effect more realistic.
Virtual Surround Music - Ups the music to 2.1 Virtual Surround (anything above 2.1 is not supported for music on the engine, unfortunately).
Amnesia The Dark Descent Remastered - This mod adds Parallax Occlusion Mapping, updates the game's shaders and allows every light source to cast shadows. Moreover, it adds more reflections and allows players to see through windows. These are just some of the features of this massive mod.

The only things that can be unlocked are particles, some animations and texture animations. This is the same for all other HPL-based games!"
