The closed beta for Dragon Ball FighterZ that was supposed to take place soon has had a slight delay. This is due to the big demand that the game has so they want to make sure more people take part in it.
Bandai Namco announced on Facebook that sign-ups for the Dragon Ball FighterZ closed beta will now take place on August 22, 2017. The beta itself will then occur on September 16th until September 18th.
Remember, this is a closed beta so you have to be chosen at random in order to play the game. Bandai Namco has yet to reveal if an open beta is taking place. There might be one closer to its release date.
The game will be out sometime in early 2018 for the PC, PS4 and Xbox One platforms. The publisher has not mentioned if the game is releasing for the Nintendo Switch. Hopefully an announcement is forthcoming on the Switch version though.
