The terrain properties are defined in the DEFAULT.TERX file found in the /Maps/DATA folder. The file can be opened in notepad or renamed as a .csv to be opened in a spreadsheet program. The file contains headers but no details about the data:


  • TSetx and RaXxx columns unused
  • Mx columns are movement penalties for moving through the terrain based on the movement types. These are the same movement types that can be assigned to a unit in the DEFAULT.UNIT file.
  • Dx columns are Defense values based on the attack type as per units (Ground, Air, Indirect, Close)
  • Sup - undefined
  • Wear - undefined
  • Entrch - Entrenchement bonus
  • Nav? - True = naval
  • Trp? - True = Tropical
  • Des? - True = Desert
  • Alp? - True = Alpine
  • Frz? - True = Freezable
  • Vis? - True = Low Visibility
  • All columns after this point define what mesh/textures to use for a given terrain type.
