An implementation of a landwalker server is located in `login/`&&`shard/`. This includes a functional login server and a dummy shard (supporting the minimum amount of packets necessary). There is minimal support for NPCs, and minimal support for player interaction (chat & player movement being mostly it).
Dump and decompile the `Assembly - CSharp.dll` assembly from the fusionfall main.unity3d, using a tool like [ilspycmd](https://www.nuget.org/packages/ilspycmd/). The full output source can then be passed to `genstructs.py` script located in `tools/`, which will handle scraping constants and calculating structure padding. See the script for details on usage.
