Cold Comfort is an asymmetrical competitive 5v5 PvP  horror survival game that is set in the immediate aftermath of the zombie apocalypse. The players – Survivors and Gamma Prime alike – are thrown into a hostile game world where they need to make a simple choice: Will they play as a team or will they try to survive on their own?

This choice is forced onto them by an atmosphere of imminent danger and the overwhelming odds of a world that changed too suddenly.  Behind the curtains of this struggle for survival a much bigger story is playing out – a story involving a huge pharma corporation with a vision and all the things that can go wrong, because humanity is simply not ready for immortality.


Rough Justice is a single player time based management game. You run a private security contracting agency, by hiring, managing, training and deploying agents; dealing with fugitive recovery, repossession and private investigative contracts.
