ワンピース 海賊無双
One Piece: Pirate Warriors/Kaizoku Musou: PS3 Exclusive
Ace feels useless watching his "dad" and brother try saving him. However, he also feels happy. Luffy asks Ivankov to inject him with another Tension Hormone so that he could get back up and not feel the pain. Ivankov denies at first but soon does so. Hancock helps Luffy fight against Pacifista and Sentomaru. (in the anime/manga it was Smoker) Whitebeard also fights multiple troops and takes on Kizaru. Finally Luffy reaches the scaffold but Garp stops him. Luffy punches him and continues running. He reaches Ace but Sengoku transforms into his buddha form and punches. Luffy counters with Gomu Gomu no Fuusen (Balloon) and saves Ace. The two take on multiple marine troops together.
Non-Canon:
They go to reunite with Whitebeard and then fight Aokiji again.
