The 2B character pack, which is included with the game’s Season Pass, will also feature an additional costume for 2B, 2B-themed extra parts and stickers, additional weapons for 2B, NieR: Automata-themed background music, and a NieR: Automata-themed stage.
Here is an overview of the character, via Bandai Namco:
A new guest character will be joining the stage of history! Meet YoRHa No. 2 Type B from Square Enix‘s NieR: Automata. 2B and her dual blades, Virtuous Contract & Virtuous Treaty, are designed for combat against machine lifeforms, employing acrobatic leaps and mid-air slashes, lightning-fast evasions and perfectly coordinated strikes! She will be making her way to the Soulcalibur VI along with her own stage and background music.
