Nicolas Games has revealed the sequel to their debut title Afterfall: InSanity through the creation of a Facebook page in which they plan to update periodically as the game develops. Afterfall: Pearl of the Wasteland is set in the far future, 63 years after the disaster. Past societies have fallen, and what remains are tribal societies and the remnants of the Republic.
Not much has been revealed at this point, but the game certainly does seem interesting. We will continue to follow this project as more details are revealed.
