,,Well, well...isn't this just like...OLD TIMES,, ? This is Old Times mod, and the goal is to restore the original Half-Life 2 Story with all of his content. Unlike other mods, OT will use the original beta content from the leak, but will be competed and full fixed.
That's right, this is the WC Mappack, now compiled. More info in description.
This is WC Mappack, WC comes from Worldcraft.
It contains a total of 1300 maps, featuring early and late concept.
Anyway, there still are some maps that are not fully working, but are few, so don't worry.
Here is a tutorial about installing:
Just open the archive, and pick up a folder, there you'll see some maps, just extract them to hl2/maps folder.
If that folder has a subfolder with some .lst files, put the in hl2/maps/graphs
