How to add long names to maps via your mod. For example, mp_strike becomes Strike on the loadscreen.

Using the Mod Arena file

To add longnames to maps (e.g. instead of mp_strike it will show Strike), then you must use the cod4maps.arena file in your mod.

To do this, you will need to place the file in your mp folder in your mod folder. Now you will have to add this asset to your mod.csv, like so:

rawfile,mpcod2maps.arena

If you wish to edit the cod2maps.arena file, place a new nested entry at the bottom of the file, like this:

{
      name    mp_custom
      longname  Custom
      gametype  dm war mycustomgametype
}

This should be useful for any modders out there. :)
