Interestingly, the beta is launching with scratch tickets, which look a lot like loot boxes. In effect, they each require some microtransaction money. In exchange, they provide cosmetics. So yeah. They’re loot boxes.
There’s a bit more to it than that, however, as it looks like there are actually a couple different variants of these scratch tickets. One type of scratch ticket can be obtained by FUN points. If you’re not aware, FUN points are a sort of in-game currency which are earned with activities like daily logins, helping out other players, and so forth.
Other scratch ticket types include AC scratch tickets and SG scratch tickets. AC requires buying these tickets with AC, which is Arks Cash. SG requires buying these tickets with SG, which is Star Gems. You can learn all about them here.
