Dragon Ball FighterZ will have its final beta this weekend, which is open to all. Those who have pre-ordered the game get early access on January 13, while everyone else gets to play for 48 hours from January 14 to 15.
The roster from the closed beta will be returning, with Goku, Vegeta, Frieza, Cell, Krillin, Piccolo, and Android 18 all being available again. Joining them for the open beta will be Adult Gohan, Kid Buu, Nappa, and Beerus. This news comes from Famitsu (translated via Siliconera). Some of the other announced characters, like Tien, Gotenks, Hit, and Goku Black, won't have a beta debut. You'll just have to wait until the game releases to play them.
Dragon Ball FighterZ will launch in North America and Europe on January 26, 2017 for PC, Xbox One, and PlayStation 4.
