This installment brings some drastic changes in the gameplay mechanics of the Bloody Roar series.
The Beast Gauge still remains in the series, which allows the player to switch to a Beast Form. However, unlike previous installments, the Beast Gauge can now be charged up with the Charge Power, by maintaining the Beast button, at the expense of health. In addition, characters can still Beastorize without the Beast Gauge being filled up completely.
The Beast and Health gauges are now intertwined, if his health meter is completely depleted, the player will automatically transform himself into his Beast form and fight with his Beast Meter as his, now, Health meter for the remainder of the round. In the same way, if the Beast Meter is empty during the Beast form, the fighter will automatically come back to his human form (if his Health meter is not empty too) without having to take a Guard Breaking attack from his opponent like in the previous games.
The Hyper Beast Mode returns also but can be attained differently than the previous games. This time, the fighter has to be in human form then uses the Charge Power until he spends all the remaining health. Once done, the fighter will transform into his Hyper Beast Form and remains in this form until the end of the round.
