Back in June, we learned about some free content coming to Sword Art Online: Fatal Bullet Complete Edition. We now know the bulk of that content is coming on Aug. 22nd, 2019.
The game's free update will include new weapons and costumes. The costumes include a Prince Head from Katamari Damacy, Genpei Touma Den Face Paint, a Pac-Head from Pac-Man, and Pooka Goggles from Dig-Dug.
There will be a second update later this Summer that will add in higher-difficulty co-op dungeons, and then an update in the Winter that will include additional story content.
