So are you saying the krypt is literally different for every single player? If that's the case then whatever, though it's still better than lootboxes because LB's were pretty much unlimited. The Krypt eventually has an end to unlocking everything.
Yes everything is random and it will be different for every person. You can use in game currency to reset the boxes though so once you clear it out you can reset everything and do it again ... problem is from what has been posted a lot of the stuff is consumables and crafting items.
So essentially they put in loot boxes that use in game currency so that you will get tired of the rng and use real money to buy the item you want.
Its great for replay ability but so far from what is reported its gonna be like injustice 2 where you might never find an item ... unless you want to pay with real money.
Its bullshit, and I put most of the blame on WB, but NRS should atleast be honest.
