You are trying to survive a pandemic of rabies, with key 'zombie' themes but with considerations of realism. A serious game with dark elements to it.
The game does NOT feature mutants, aliens, "bosses" or any other foreign incarnations, the zombies are all ex-humans each with their own stories behind them.
The character in-game is entirely fictional but there is intentional crossover between stories in this series, including the one about myself.
