Setting up a map for hardcore mode

Creating a hardcore map is the same process as creating a ZPS map, the only exception is that you need to prefix your map with "zph_" instead of "zps_".

Also keep in mind that your map should be adapted to the ZPH game mode, you have to take in account the reduced damage of survivors, multiple zombie carriers, 100% infection rate, 5 minutes for the survivors to stay alive to win and so forth.
