ok i will tell u how to compile a map
BUT NOTE: this doesnt include the wads like hlcsg -nowadtextures
first step: DONT create any batch files
2 step: take ur mapname.map file
3. DRAG it over hlcsg.exe
4. " " " hlbsp.exe
5. " " " hlvis.exe[only if u have lights]
6. " " " hlrad.exe[only if U RAN vis]
7. get the mapname.bsp file
8. copy it to ur czero/maps folder
czero is exactly the same as 1.6
but has zbotcz[which is downloadable] and a single player campaign and another game called "Deleted Scenes" which is SP.
and has new maps such as de_dust2_cz or de_nuke_cz which r remakes with some improvements like xtra furniture and uses new wads
Edit: CSCZ also comes with new models[but fpsbanana models r 100% better] and the hostages have "feelings"
