The level (FORTRESS.BSP) must be copied in the quake/id1/maps-directory. Start it with MAP FORTRESS out of the console (by pressing the ^-key).

--------------------------------------------------------------- ATTENTION : Because a fort must be outside (else it is no fort), the level consists of a huge room. Thatīs what QUAKE does not like. In order not to see DISAPPEARING TEXTURES or GREY PLANES, you have to change two QUAKE-C-variables. Simply type the following two lines in the console (by pressing the ^-key):
R_MAXSURFS 1000
R_MAXEDGES 2700
frag it! And: DEATHMATCH 2 rulez!
