In a move similar to previous Dragon Ball Z fighters, Dragon Ball Z: Battle of Z producer Shohei Seiki recently confirmed with Siliconera that the upcoming game will include "What if" scenarios.
While there wasn't much detail provided as to what those scenarios will entail this time around, Vegeta's voice actor hinted at one, saying Goku and Vegeta's first meeting might be different than before. There will also be a scenario that has players battling Goku's entire family, including Bardock.
Battle of Z plays out missions from the perspective of being good or evil, and while villains will be able to team up with heroes, they won't necessarily take kindly to sharing energy or being healed.
Seiki also mentioned the inclusion of characters from Dragon Ball Z: Battle of Gods, which was previously detailed, but only confirmed Super Saiyan God level Goku. We'll have to wait to find out what other surprises lie in wait for Dragon Ball Z: Battle of Z, which is set to hit PlayStation 3, Xbox 360, and PS Vita in Japan, North America, Europe, Latin America, and Brazil.
