Killer Instinct's single-player Arcade Mode will not be released until all of Season One lands on Xbox One, Microsoft Studios game designer Daniel Fornace has told OXM.
Fornace said at launch, six characters will be available for the game, and once the other two characters are released - bringing the total to eight - Arcade Mode will be released.
"Our Arcade mode is going to come out when we've done the eight characters," he said. "So once the last character comes out then we'll have Arcade."
It will still include offline play in the form of Survival and Dojo Modes.
"Survival is like our endless mode," Fornace said. "The way it works is you pick a difficulty and you go in, and you're basically playing a long chain, and after each match you regenerate health, but as you go on you generate less and less, and even if you do beginner difficulty, as you get to the higher numbers the CPU does start getting tougher, so you'll still hit a limit.
"You set your difficulty to where you're at - so if you set it to Champion it'll start hard and get even worse.
"The Dojo is our big tutorial mode. We're teaching you about Killer Instinct, but we're also trying to teach you about fighting games in general, and their terminology, because often you'll hear people talk about fighting games, and you know they just don't know what they're talking about."
Killer Instinct will launch with free-to-play character Jago with other characters running you £3.99/€4.99/$4.99 each. The Season Pass will run you £16.99/€19.99/$19.99 and comes will all eight characters.
It launches alongside Xbox One later this month.
