Amnesia 64

64-bit Windows port of Amnesia: The Dark Descent

Key changes:

• Can be compiled in both 32-bit and 64-bit modes using VS2019 with latest build tools.
• Single solution file for all projects (main game, HPL2, dependencies and editors). No need to compile the engine separately.
• Produces self-contained .exe files without dependency on 3rd party dlls (this prevents cluttering user's game folder with 64-bit dlls).
• Some libraries were changed, most notably:
  • SDL2 was upgraded from 2.0.4 to 2.0.12
  • alut was replaced with freealut
  • Newton Dynamics was upgraded from 2.08 to 2.32 (I simply couldn't find the source code for 2.08)
  • Fbx support is temporarily removed (I'm planning to re-implement it using OpenFBX)
