This package contains standard CTF and DMPCF maps for dedicated servers since these servers may not have full packages. This pack is not needed for clients as these maps are already in the game.
Maplist:
CTF_Chaos
CTF_Forbidden
CTF_Trainstation
DMPCF_Tower
DMPCF_Warehouse
Copy the map to your Painkiller\Data game directory, for example C:\Program Files\DreamCatcher\Painkiller\Data
