atrim

A legal, unmodified and DRM-free copy of Amnesia: The Dark Descent and/or Amnesia: A Machine for Pigs is required.

atrim is a client for Frictional Games' Amnesia: The Dark Descent that offers bug fixes and enhancements to the HPL2 engine and base game. Coming soon will be additional fixes and enhancements from, along with support for, The Chinese Room's Amnesia: A Machine For Pigs.

The game and engine can also be ported to significantly weaker (or unorthodox) hardware which are usually below the official minimum specifications.

atrim is currently being maintained by one person (@RoozerXC). If you want to contribute to atrim, feel free to fork and submit your own pull requests, as long as everything follows the Code of Conduct (or Anti-CoC).

Important

• This port is based on the official Amnesia: The Dark Descent version 1.4.3 (1.41b) source code release from October 12th, 2020.
• Mods installed from the Steam Workshop, including Custom Stories and Full Conversion mods will not work here!

Caution

• DirectInput controller support on SDL 1.2.15 is very poor! We need your help! (see issue #21)

For a list of changes, read CHANGELOG.md. Special thanks are in THANKS.md.
