 Story In Development:
When Mortewood was chosen by the U.S. Government as the first town in America to receive a test for a cure for Cancer, named Project H.O.P.E, naturally the citizens were overjoyed. They thought of it as a blessing from God. But what happens if this so called ‘blessing' becomes a curse? What happens if the cure evolves into a much more terrifying disease? And what the hell are you supposed to do when you’re stranded inside a town full of hungry side effects? Commander Eric Slade will soon find out what happens when gene manipulation goes wrong, and what the consequences of playing God are. With the help of a massive arsenal of weapons, plenty of ammunition, and an old man wielding a shotgun, Slade will have to fight his way to survival and escape Mortewood before the town is ‘purged’. Oh, and did I mention there will be plenty of blood thirsty zombies, psychos bred by the horrors they have seen and the US Armed Forces to deal with as well?

Welcome to Mortewood, twinned with Hell.
