Regarding Dead Cells the Steam Quest, Dead Cells + a DLC 7 other games are a part of the Humble Bundle's Humble Choice for the month of August, if you bought the game & the DLC on Steam would be $14.98 but for the Humble Choice you'd be paying $14.99 + tax if your region taxes, some people were buying games just for the ARP, paying only a dollar some cents more you'd get more for paying literally a little more, it's a monthly subscription, but you can cancel at any time keep the games after you paid
