Starte die Map einfach im Editor über die .cry Datei !!!

Oder so wie es bei www.crymod.de halt steht :

Installation:
  1. Go to your Crysis level folder: -> Electronic Arts/Crytek/Crysis/Game/Levels/.
  2. Eventually backup a existing Level folder with the same name.
  3. Extract the levelfolder from the downloaded archive if necessary by using an extracter such as 7-zip.
  4. Copy the downloaded levelfolder into the Levels folder.
  5. Start Crysis
  6. Open console (with the ~ key) and type in "con_restricted 0" (without "") to allow access to console commands
  7. Load your custom map by typing in the console "map mapname" (Without "") and press Enter.
