The next issue of Dengeki Playstation will shed some light on the battle system for Ys: Foilage Ocean In Celceta, the Playstation Vita remake of Ys IV. The system will be party based with similarities from Ys 7, a later game from the series. Players can change teh character they control with the press of the square button. Each character will also have access to three different attacks. Each attack will have a different effect depending on the enemy.
Even though you only control the action of one character at a time, the game will utilise the rear touch pad to issue orders to you AI party members. The two example gestures listed are pinching in, which makes the character attack and pinching out which priorities evasive actions. Characters will have skills which require skill points to use. Character can also acquire new skills. Dengeki Playstation also lists some of the party members your main character will encounter: Nina, Ozuma and Kanririka. Ys: Foilage Ocean In Celceta will be released for the Playstation Vita on September 27 in Japan.
