Looks like Bestbuy, Gamestop and Amazon are the first stores I’ve seen that has the upcoming Killer Instinct Combo Breaker Pack on sale for the Xbox One. Once only available as a digital release, the Combo Breaker pack consists of the original eight characters from Season 1 and upcoming characters TJ Combo and Maya. This will also include new characters for the upcoming Season 2 as they are announced and released.
The Killer Instinct Combo Breaker pack will cost $19.99 and will be available to physically pick up on 9/23/2014 for the Xbox One.
