They’ve confirmed there won’t be a battlepass. And I’m not going to complain about them offering more content down the road for anyone willing to pay, especially considering it’ll likely get a massive discount at some point.
I’ll take this traditional DLC model over a battle pass model any day.
Play the games you know. If you know when a character is supposed to say “Get to the helicopter now we are leaving!” When you hear them say “Kommen Sie zum Helikopter, jetzt fahren wir los.” you’re more likely to have that 10-20% you wouldn’t otherwise understand click.in your head.
Also I recommend any games set in a region where the language you want to learn is set. This is because all the signs will be in that language.
