Now if it were a free battle then that would be good because it gives you something to earn while playing without needing to pay for even more stuff.
Having a payed battle pass along with paid DLC is a bit too much.
I think if they were to do a battle pass then they should make it similar to battle for neighbourvile because they get it right (minus the characters and upgrades in them of course).
They could release a massive battle pass each month for free with new weapon skins, accessories, shaders all of the customisation we have now and more. And maybe the reward for reaching the end could be a legendary predator skin that changes the look completely. So maybe something like Wolf predator.
But it would suck if you end up missing out on an item so to compensate for that they could allow you to get the smaller cosmetics with Veritanium and the legendary skin could be unlocked with a challenge once the battle pass is over.
And of course if they needed another way to monetise the game then obviously you could pay to skip tiers or something along the lines of that.
