Side scroller/crawler/marching, I’m not really sure what you call this game genre but if you’ve played Merc Story before, the game looks something like that (or at least the promo video looks like it).
Hopefully the Gacha chance isn’t as bad as Merc Story because that’s the only reason why I stopped playing it. The iOS version will be releasing first in early July while the Android version is slated for the 3rd quarter.
