Dragonball Z: Battle of Z‘s Jump Festa, which was previous released in Japanese, has now been subtitled and narrated in English. It shows players the large scale boss battles, as well as the partner system and online multiplayer.
When players team up with each other in battle their partner gauge increases, which allows for stronger team attacks. There’s also a Battle Royale mode that lets players battle each other in a no-holds-battle. The trailer posted below shows off all these features and more.
