 Secret level:

 On the CD go to the subdir GAMEDATA\RESOURCE\VIDEO and look for the
 file unsupported.zip. Create a new dir in the folder EPISODE, e.g.
 \EPISODE\SECRET. Now unpack the zip file to this dir, two new
 sub folders should be seen \COG and \JKL. Now create a file in
 the folder \SECRET\ and name it episode.jk. This file should have
 these few lines:

 "Secretlevel"

 TYPE 1 # single-player

 #SOURCEFILE ZbtryCbjre
