Unfortunately yes. I understand that PS2 is a quite international game and there is no such thing as servers by country. But I think that having the outfit internal comms in your mothers tongue is nice. And I was not able to find any german outfit on Woodman VS so far.
Bottom line: I speak english. Most of our members will hopefully speak english to a degree. But still, internal comms are german. Sorry.
You might have a look at
