I don't understand something, or is it supposed to be this way?
It seems you need to choose a different Data Pack in the corresponding window of the launcher.
Another option:
baratorch
...
Eng+rus will also work, but to have RMX and Conflux in the game,
you need to add the line {ArmageddonsBlade} = 1
to the file \_HD3_Data\Packs\Eng+rus_en\Pack.ini
but instead of curly brackets, you need to use less than and greater than signs; the forum doesn't seem to want to display them.
