Ys X introduces the brand new Cross Action system, gone are the party system and Damage Types. The game features only two playable characters—Adol and Karja.

The Cross Action system allows the player to fight using two modes, which can be interchanged seamlessly by holding a button:

Solo Mode, a fast paced system that utilizes step and dash-based movement where the player controls one character with his or her partner being controlled by the AI. In addition to unleashing various skill attacks with Adol and Karja, the player can switch between characters mid-attack to trigger a partner cut-in attack, making it possible to drive into the enemy with consecutive blows that leave them no opportunity to strike back. Additionally, the speed attacks (attacks with a blue aura) unleashed by some enemies can be automatically dodged with Solo Mode’s dash. The player can deploy technical actions, such as dealing damage by unleashing a counter attack from an automatic dodge that hits surrounding enemies.
