The Xbox One reboot launched alongside the system as a free-to-play title. Gamers had access to one character, Jago, for free, and had to pay extra to unlock access to the other characters. At the start of January, Microsoft and developer Double Helix released a patch that introduced a character rotation system, changing the free character on a regular basis. After changing from Jago to Sabrewulf, the free character was again changed last week to Thunder. Now owners of the free version will instead be able to play as Orchid. Known as Black Orchid in the original Killer Instinct, she's a secret agent with the ability to turn into a fire cat. Players who wish to unlock other characters have two options. The Combo Breaker pack includes the first eight characters for $19.99 / £16.99 / €19.99. Alternatively, the Ultra Edition ($39.99 / £34.99 / €39.99) includes the same eight characters from the Combo Breaker one, plus character accessory packs, costumes and the original Killer Instinct arcade game.
