TL;DR
EA says UFC 6 update 1.006 is available now, bringing three new fighters, five free skins, and various gameplay tuning changes.
EA released UFC 6 update 1.006 on October 15, bringing three new fighters and balancing tweaks to the octagon. Ismael Bonfim and Joselyn Edwards join the active roster, while Benson Henderson 2012 is tucked behind the Fighter Pass. Players who own the Standard or Ultimate Edition can claim five free skins from the Championship Skin Collection in the in-game store between October 15 at 10 AM PT and November 16 at 10 AM PT.
EA reports that ground game responsiveness has been improved. Heavy roundhouse and calf kicks are now faster but less powerful, which EA calls a net buff because speed increases outpace power losses. Additionally, the Anvil Flow State damage and duration bonuses drop from 35 percent to 25 percent.
