This new trailer for Dragon Ball Z: Kakarot goes over a couple of key features, explaining how both support characters and additional playable characters work within the game. Obviously the story focuses on Goku, but he doesn't have to fight alone. Computer controlled allies such as Krillin, Yamcha, and Tien can help out in combat, pulling off special moves or contributing to your combos.
And sometimes, you won't even be playing as Goku. The video highlights different playable characters like Gohan, Piccolo, and Vegeta. You can explore the world with each of them at various points in the story, and there are side quests that only specific characters can embark upon.
We've said this before, but the more we see of Dragon Ball Z: Kakarot, the more promising it looks. We're looking forward to trying this one out for ourselves when it launches in January next year.
