Mass Effect Trilogy languages (German?)

Hello,

I've been given the "Mass Effect Trilogy", however I haven't broken the seal on the box yet, because it says "English Text & Audio" on the back. I'm only interested in playing computer games in German. Before I return it, can someone please confirm if the "Mass Effect Trilogy" is indeed only available in English? Also, if so, do you know if it might be possible to download a German language pack separately?

Thanks for your time.
