Mixed languages | Does Halo 5 support PT-PT?

So, my Xbox system’s language is Portuguese (Portugal), but when I play Halo 5, the whole game is in English. This is common though. Most of the games I own will display English language instead of Portuguese… and when it’s Portuguese, it’s usually Brazilian. It’s VERY rare to see games displaying correct PT-PT language. However, I’ve been noticing some things in Halo 5 being translated to PT just out of the blue. Here’s some screenshots:

Now, personally, I have never seen or heard Halo 5 on Portuguese, even Brazilian (although, to be frank, I’m quite thankful that the voices are English). This is no issue to me as English is like my second mother language, but I’m curious to know if Halo 5 supports least Brazilian?
In case Halo 5 doesn’t support European Portuguese, I want to point out, as a native speaker, that the description for the Voices of War screenshot reads and looks like it’s in that language. Is the game using Xbox’s store to display the description?
NOTE: European Portuguese and Portuguese (Portugal) are the same, just different names. Brazilian, although it’s very similar, is spoken quite differently and they adopt several English words, sometimes for different meanings. For example, they commonly use “Time” instead of “Equipa” which stands for “Team”.
For Brazilian readers, I mean no offense. Just a friendly thread with no racial or hostile intentions. Thank you.
