Campaign names are the ones that flash in the intel screen and some other places too, also they should appear in TE. Many of the strings are also used throughout in Falcon 4 UI like in setup and so on. All the names seem to be included only in the RV file, where AF and OF only includes some specific rather theater related strings.

These following files are pure text files which you can edit directly from your favourite text editor.

Allied Force

Campaign names comes from art\main\theater.irc file.

Open Falcon

Campaign names comes from art\main\theater.irc file.

Red Viper

Campaign names comes from the art\main\lcktxtrc.irc file.

To replace campaign names you need to be careful, for example there is these lines.

[ADDTEXT] TXT_SCENARIO_1 "Scenario 1"
[ADDTEXT] TXT_SCENARIO_2 "Scenario 2"
[ADDTEXT] TXT_SCENARIO_3 "Scenario 3"
[ADDTEXT] TXT_SC_2 "scenario 2"
[ADDTEXT] TXT_SC_3 "scenario 3"
[ADDTEXT] TXT_SC_1 "scenario 1"
