This is a .map which you can use to get a better understanding of how to make maps for Digital Paint Paintball II. It includes support for 1-Flag and 2-Flag CTF as well as Deathmatch.
This includes BSP along with all the necessary .wal textures, compilers, and anything else you need to get started. Extract to C:BSP. See included install text for details.
Just run it with the path of the quake1 paintball .map file as a parameter, and it will create a new version of your map which should be almost totally converted for DP, as oldmap_q2.map.
