Unless you are looking for a gacha intensive game, or a game that does have lots of WW2 warships you'll probably not enjoy this game. The difficulty curve is riddiculous, a few 5+stars ships will make certain maps/difficult tier practically child's play while suddenly enemies one tier above might as well be godlike to you. The supposedly tactical aspect of formations are practically nonsense. The ship that got place in position labeled as less likely to be targeted can totally got focused fire on.
Tl;Dr ver in case you're wondering, this is a heavily pay to win game, and you'll only enjoy it if you're willing to put a significant chunk of money into the game.
Gacha rates are garbage, game wants you to pay to get good ships, and the campaign is impossible even with leveled up 5 star ships. This game is worthless garbage, I hope whoever created it dies in ruin
