Dragon Ball FighterZ is played in what is known as 2.5D, with 3D characters fighting on a 2D plane. Each player Controls three fighters that they selected, fighting opposing teams with one fighter at a time. However, you are able to call upon your other Team members to help out with assist attacks, as well as have the option to switch out characters as you would so please.
This type of gameplay has been implemented in many fighting type video games these days, including the Morbat Kombat Series, the Marvel vs Capcom Series, the Injustice Series, and the Guilty Gear Series. This time around, it is seen and used with the famous characters of the Hit Dragon Ball Series.
