Mortal Shell is an action role-playing video game developed by Cold
Symmetry and published by Playstack. It was released on 18 August 2020
on PlayStation 4, Xbox One and Microsoft Windows. A remastered version
titled Mortal Shell: Enhanced Edition released on 4 March 2021 on
PlayStation 5 and Xbox Series X and Series S.

The developers created Mortal Shell as they thought there was a gap in
the market for video games evoking deeper emotional experiences. They
were influenced by FromSoftware's 2011 game Dark Souls, similarly
creating a setting with a dark atmosphere and populated with characters
giving players cryptic information, and designing gameplay based around
challenging melee combat, but still intended to change things up and
create their own take on the concept. While some changes to the Souls
formula were creatively driven, such as giving players only a limited
amount of consumable health items to encourage use of the
health-leeching mechanic, compared to Dark Souls' Estus flasks, other
changes came from the limitations of being a smaller developer: for
example, they could not develop the same amount of armours, weapons and
character builds, and instead developed four "shells" with different
play styles and backstories
