First you could go download pakscape here.

Save it into your CoD folder and unpack it into its own folder in the Call of Duty folder called PakScape.

Making A PK3

Now make a new folder with your map name in your Call of Duty Main folder.

Now add all the folders like *maps\mp *levelshots\layouts *mp *sounds *soundaliases and add your read_me here too.

Take your .bsp and all your .gsc files and put them in the maps\mp folder.

Next place your ARENA file in the MP folder (NOTE: not with the .bsp!)

Now for a loading screen put the .jpg in the levelshots folder and for a layout put the .dds in the layouts folder.

Now for any sounds your are using place them in the Sounds folder.

Now for the sounds you need a .csv file. Place that in the soundaliases folder.

Now open PakScape and create a new file.

Now copy everything in the folder you made with all the files.

Now paste them into your new PakScape file.

To save it go to File>>Save As and type in your mapname then select Quake 3 Pak (*.pk3)

Then your have yourself a pk3.
