8BitDo has created its first wireless Xbox controller in partnership with Rare, a game studio acquired by Microsoft. The $89.99 8BitDo Ultimate 3-mode Controller for Xbox — Rare 40th Anniversary Edition (yes, that’s the product name!) The wireless connection works through a small USB dongle and not Microsoft’s native Xbox Wireless protocol. The collaboration comes as Microsoft’s own custom Xbox Design Lab controller has been on hold for months now. 8BitDo’s Rare 40th anniversary Xbox controller goes on sale today, priced at $89.99.
