Making a pk3 - Its kind of an easy thing to do, but there are a few things that really need to be done right. Make a zip file called <mapname>.zip with the following directory structure; /maps/<mapname>.bsp your map file /maps/<mapname>.aas your map's bot file /levelshots/<mapname>.jpg your map display shot /textures/<mapname>/<mapname>_<texturename>.jpg a custom texture /textures/<mapname>/<mapname>_<texturename>.tga another custom texture /scripts/<mapname>.arena makes your level turn up in the menu /scripts/<mapname>.shader a custom shader for your map /<mapname>.txt some info about your map Once you have made the .zip file you need to rename the <mapname>.zip to <mapname>.pk3 If you use Microsoft Windows, you may need to enable file extension. You can do it as a folder option from the Windows Explorer menu. Then place the .pk3 file into a zip file with a copy of the readme.txt file. Placing it in a .zip makes for easy download as some servers/browsers mis-read .pk3 as text (because of MIME settings). Thats about all there is to it.
