Some big changes will come to BP, at least for the current year. It is unknown whether these will remain for upcoming years. Read on.
- This year it will be possible to switch between Chapters and decide which Chapter you want to grind, within a Season. So you can grind the first X levels in a Chapter, pause it, grind another Chapter for a while, pause this too, then return to the previous Chapter.
- Unused BP Points will be available for spending in a special Store. This Store will open after you finish a Season (all 3 Chapters). As you may know, during BP, daily missions award BP Points, but after the player is done with the Season, all points went to waste. Now this will change, Points will be the currency in the new Store. The standard Token system will stay the same.
- This special Store will feature stuff from previous BP iterations, but not only. You will be able to buy Commanders from previous BP Seasons, most probably Tier 8 Premium tanks, 2D/3D styles etc.
