This is an idle gacha game.
๐ Pro: Liked the minimum of gore/blood splatters present in the game when beating up enemies.
๐ Pro: UI is simple and game allows you to check how long idle rewards are built up before giving you the option to collect it.
๐ Con: Story is trash. It's basically someone cloned the heros with lots of padding to inflate the number of chapters.
๐ Con: A week of grinding for currency to play the gacha (not including events or achievements) allows only for 3 full hero gacha clears.
Combine this with the fact that you have to pull the gacha in order to level up the shop to make rare heros more frequent leads to very slow ranking up of characters.
๐ Con: Character ranking up works in set of 3s. 3 copies of same rank character makes it a Rank+ character. You need 2 other rank+ characters in order advance to the new rank.
Combine this with the previous con and you can see how tedious ranking up characters become.
๐ Con: This being an UBISOFT game means that of course that the monetization is overpriced.
