Fighting and the Gigant Gauge
The fighting in One Piece: GIgant Battle takes place on a 2D plane. Items can be used and some items can be picked up and used offensively. Basic attacks are modified by pressing different directions on the D-Pad. When a player guards at last second, it is called a Bingo. A Bingo blocks all incoming attack damage. Bingo also increases the Gigant Gauge.
When a player fills the Gigant Gauge, the character earns a Gigant point. Gigant Points are reresented under the Gigant Gauge by a little fireball. To use a Gigant Point, press L or R to bring up the Special Attack menu. Follow the button prompts to execute the attack. Stronger specials use more Gigant Points.
Pressing L or R and all face buttons (A,B,X,Y) with a full Gigany Gauge and full Gigant Points causes the character to enter Heat mode. Heat mode gives character a major stat boost and makes them stronger, but also drains health while character is in this mode.
Characters Level up with each battle and unlock Stat Points. Players can allocate Stat Points in one of 5 categories: Health, Attack, Special Attack, Items, and Support. Players do not have access to all of the characters' special attacks and have to unlock all of character's special moves by buying them with the money earned in battles.
