This is the compiled MOD folder. It contains everything needed to import the models, textures, etc into Hammer for use in the game.

This entire folder goes into the Steam/steamapps/SourceMods folder. Once there, restart steam and it should be in your My Games list. Right click it and select launch parameters and type in -allowdebug. This will allow the program to run with debug parameters. That's it! You're playing NC: Source. You can then go into the Source SDK and setup a mod configuration for it so that Hammer will load everything you need for the mod when you have that configuration selected.

Enjoy guys!
