Mortal Shell II will be significantly longer than the first part. The developers at Cold Symmetry stated that playing through the game will take 30 to 40 hours. The final time depends on the player's skills and how thoroughly they explore the open world.
For those who want to complete the game 100%, the developers estimate it will take over 60 hours. Mortal Shell II will also feature "New Game+" and increased difficulty with more valuable rewards.
For comparison, the original Mortal Shell takes approximately 10.5 hours to complete the main story, and all content can be experienced in 23.5 hours.
An open beta is currently available on PC, PS5, and Xbox Series X/S. It allows players to experience about three hours of the game, and some progress will carry over to the full version. Mortal Shell II is set to be released on August 20, 2026.
