This is my first submission on a game, so... please be mercyfull ...
As usual: Extract the "czde_dust.wad" file in the "......\Condition Zero\czero" folder.
***Note: if you are using the game in other language than English, the "czde_dust.wad" file should be placed in the "......\Condition Zero\czero_LANGUAGE" folder.
****Language ex. czero_spanish, czero_german... etc.
Oh, and sorry for the crappy screenshots, no video option was on (laptop running).
