Customers who purchase the Pin Ultimate Edition of Killer Instinct still get the game. A download voucher for the Ultra Edition of the game, which includes all Season 1 characters, a season pass for all costumes and accessory packs, early access to all Season 1 content and a copy of the original Killer Instinct will be included. The case will double as a folio for a 16-pin set designed by Mike "Gabe" Krahulik.
The Pin Ultimate Edition's page doesn't specify how many units are being produced, but pin designer Krahulik wrote in a Penny Arcade post that it's "not a lot." Pre-orders are currently live through the Microsoft Store.
