Could Gaijin please extend the unlocking period of Maus? I quite hard for a newcomer who purchased a few premium tanks on 1 Nov to unlock the Maus on 6 Nov.
If you manage to put any amount of research on it, it will stay researchable and you can finish it on a later date.
There’s no time limit on unlocking the Maus.
There’s only a time limit on putting any amount of RP into Maus research.
I still lack of 2 rank 4 tanks, really tough.
