Microsoft has announced the pricing structure for Xbox One launch game Killer Instinct. While the title will be free to download and play with one character, Jago, additional fighters will be available for purchase starting at £3.99 each; Sabrewulf, Glacius and Thunder have been revealed so far.

Players hoping to significantly boost the roster will be able to purchase one of two discounted character packages. Priced at £16.99, representing roughly a 50 per cent saving, the Combo Breaker Pack will come with the game’s first eight characters (six at launch, plus two before their official post-launch release). Meanwhile, the £34.99 ‘Ultra Edition’ will include the same characters, fighter accessory packs, costumes and the original Killer Instinct arcade game.

Killer Instinct was one of 23 Xbox One launch games announced yesterday during Microsoft’s Gamescom showcase, where it was also confirmed that every Xbox One pre-ordered in Europe will come bundled with a free copy of FIFA 14.

Microsoft said last week that Xbox One will launch in only 13 of its 21 previously announced markets this November. The eight delayed regions - Belgium, Denmark, Finland, Netherlands, Norway, Russia, Sweden, and Switzerland - will host their own Xbox One launches as soon as possible in 2014.
