About This Game
An action role-playing game in a rotting world where you are not tied to one body. The remains of defeated warriors, the Mortal Shells, can be occupied, and each one opens up a different approach to combat. Fighting is deliberate rather than quick, built on committing the sword only when an opening appears and timing parries into counterblows, and you can turn to stone where you stand, either to absorb a hit or to put extra weight behind your own swing.
