the combat is pretty simple so i assume its server-sided like Honkai Star Rail and most turnbased game
Yep that's also my thoughts btw this game is so balance and it's 100% f2p friendly some story stages is easier to beat you don't need 6star characters to beat some hard stages 5-4 stars is only needed for that. Actually this game is pretty similar to arknights so if you played arknights before the mechanics and mats grinding is similar to it.
