Capcom today have confirmed that a update to Monster Hunter Rise which includes a Sonic the Hedgehog collaboration will release on the 26th November, 2021.
The announcement, via trailer, introduces players to some rather hillarious looking layered armour for you and your buddies to give you feline friend the appearance of Sonic, or your huge wolf dressed up in a Tails-themed “Canyne Tails” costume.
It also appears that the Sonic Gear armour has a Super Sonic mode as well.
Additionally, the trailer also features ring collectables, although there are no details on how these will be incorporated into the event quest.
