Players can choose from a range of heroic characters, build their own exclusive team, and use a new card-based battle system to defeat their opponents. The game emphasizes combining cards and characters to perform special moves and have more interaction with characters from the "Seven Deadly Sins" team wearing unique fashions, including original in-game character costumes, dialogues, an intimacy system, cooking, and more.

Grand Cross will offer turn-based battles and a cardboard-only game mechanic. In each battle, you will have a team of three characters facing one or more enemies. Each character you control has two different skills, which are randomly displayed as a series of cards at the bottom of the screen.

When it's your turn, you can tap and press three skills in the order you want. A hero can attack for three turns in a round, and you can also drag a card next to the same card to combine them to create a stronger version of that skill, but that hero can only fight for one turn. The enemy's turn will come only after all your skills have been used.

Each character has five dots below their health bar, and these dots fill up during battle. When they are all lit up, you will be able to use that character's Ultimate skill, which is usually an ultra-powerful attack against one or more enemies. The ultimate is resolved using flashy full-screen animations, so it's both fun and effective.

How to get SSR characters.

As with most games, the game has a variety of heroes with four rare classes: R, SR, SSR and UR. You can get certain characters as quest rewards, but in most cases, you'll go to the "Draw" tab and use special tickets or the game's premium currency, diamonds, to draw them.

In order to get the most out of SSR heroes (the best rarities found in raffles), you need to save at least 30 diamonds. Because spending 30 will give you 11 draws, or 3 diamonds for free at a time. The most important thing is that "Spend Diamonds" will fill the "Raffle Bonus" gauge at the top of the "Raffle" screen; once it is filled, your next 11 raffles will get you at least one SSR character.
