Sui Generis [www.baremettle.com] (full release)
An open world RPG where the story doesn't wait for you. Events will transpire with or without your intervention, causing the story to be hugely dynamic. Success and failure are of equal value. Combat is entirely physics driven with accurate collisions. There are no artificial barriers/level requirements in order to wield a weapon. However, using it effectively will take practice. Armour protects only parts of the body it actually covers. Finding the right equipment will involve experimentation rather than comparing numbers.

Team up with similarly doomed survivors (human or NPC). Explore an isometric Muldraugh, KY in a vast, evergrowing map. Develop skills through play while fending off depression, boredom, and addictions. In-depth NPC encounters driven by a metaverse system that tracks off-screen survival.

No More Room in Hell 2
"When there's no more room in hell, the dead will walk the earth."
A tribute to the highly acclaimed film series in which the above quote originated from, NMRiH2 is a co-operative realistic first person survival horror being developed in Unreal 4. Taking inspiration from George Romero's "Of the Dead" series, with co-operation and teamwork, you may live long enough to fight your way to salvation.
