Hey ExcessiveSkin (nice nick ;D)!
If you backed Leviathan, there's a high chance you'll be able to grab Death&Taxes as an addon once that goes to the PledgeBox stage. But we'll also look into making the PledgeBox for Death&Taxes public this time for late backers. And the first straight-up public copies should be available in around 8 weeks in the Beyond Cataclysm shop (https://beyondcataclysm.co.uk/).
And thanks for the interest and picking up my other stuff too :)
