According to Polygon, the developer, Double Helix, has confirmed that the game will also have an option for a “season pass” that you can use to buy all the characters in one go instead of paying for individual characters. To access the other characters, players will have to pay for them. The game will be download-only and will only have one character available. As it turns out, the game will be a free launch title for the console. One of the biggest surprises of Microsoft’s pre-E3 press conference was the unveiling of fan-favourite fighting game Killer Instinct.
