Indie development studio Fool’s Theory has released a new gameplay video for the upcoming isometric RPG game Seven: The Days Long Gone.

Set in a "beyond post-apocalyptic" environment, players will be able to freely explore the sandbox world of the Vetrall Empire.

As a master thief possessed by an ancient daemon, the player is deported to the prison island of Peh on a mission that could decide the fate of all humanity.

On Peh, the player will experience rich stories of conspiracy, discovery and betrayal, set within an unforgiving world filled with mysterious technology and dark age superstition.

The game also features several movement systems, including a climbing system that will allow players to freely traverse obstacles of any height, both horizontally and vertically, giving more options to explore the environment.

Seven: The Days Long Gone is expected to launch in 2018 for PC. A release on other platforms is expected to be announced at a later date.
