The WC Mappack
Main Page for WC map pack
What is the map pack?
The Worldcraft (WC) Mappack contains 1350 VMF (Valve Map Format, a file format that represents editable Hammer levels) files. These files represent levels and areas from almost every location Valve prototyped and playtested during the six-year Half-Life 2 development cycle.
By analyzing the last-modified date of these VMFs, we can observe that the Mappack contains levels that were made from December 14, 2000 to September 25, 2003. These levels not only provide a fairly accurate timeline of locations and gameplay concepts that Valve continuously prototyped and discarded, but also provide deep insight on how the Source engine itself evolved during its development.
In terms of the general state of these maps, the Mappack provides levels that range from being almost complete and fully-functional, to being in a very unfinished state. Many of the maps are also affected by engine compatibility issues - as the Source engine was evolving, many features were being modified or discarded at a very quick rate, leaving many old levels very outdated in the process.
This means that if anyone wishes to get the levels to run in an available Half-Life game, some work is required. The nature of this work mostly revolves around fixing outdated entities and brush work so that the game can correctly interpret the level itself.
