The old team didn't really keep up with their multiple language support, for example, I play the game in Japanese and there are some things not translated
Mechs: Incinerator (???????), G2 Mechs (Honestly just add G2 in front like the english ones)
The word Equipment for the Equipment customization menu (??)
Cockpit customizations
"Back (ESC)" (? (ESC) ) in the menus
and a few others.
One other issue I know with the Japanese version is the silos are labeled with their number up top on the HUD but not in front of you when you're looking at them, it's even worse with the energy stations with 1 and 2 not being labeled. Just simple numbers being added would be simple additions.
I don't know how it is for the other languages, but the main reason why I use the Japanese client is because it allows me to type in Japanese without it becoming all rectangle blocks.
