Microsoft looks set to release Killer Instinct Classic 2 on Xbox One later this year.
Microsoft rebooted the Rare created fighting series in time for Xbox One's launch in November 2013.
A free version of the game includes all modes and one rotating character, while the £15.99 Combo Breaker Pack includes all eight fighters featured in 'season one' of the title. Additional character accessories and costumes, plus a playable version of the original Killer Instinct arcade game under the title Killer Instinct Classic, are bundled with the £31.99 Ultra Edition.
Killer Instinct season two is planned for release in 2014. Killer Instinct Classic 2 will presumably be included in a Killer Instinct season two Ultra Edition.
