From the campaign:
Another big day ahead as we unveil yet more for you! Fantastic news that we unlocked the Mishima Guide last night. You'll see there's now a surprise £3k goal at £99-£102k...I wonder what that can be? Next we're praying the Cardinal will look kindly on us and unlock the Brotherhood book before the Tsarina and her Whitestar warriors charge forth!
You can now choose the Mishima Guide as an Add On for £15 / $24.
