Microsoft has made Killer Instinct Season 3 available for Pre-order. Right now, you can go to the XBox Store and buy the Ultra Edition of Killer Instinct for $39.99 (£31.99). There are also some bonuses including 18,000 KI gold and permanent double XP boost for those that pre-order. Both the XBox One and PC versions of the game release on the 29th of March.
Co-incidentally, Microsoft has also confirmed their pricing for the PC version. Basically it’s going to follow the pricing of the XBox One version. You will be able to download the game for free, but you will only get one character. With that said you can buy characters individually or buy the various bundles.
