A new illness has been sweeping the nation recently. PS648 Z64, often called PS648, comes from a mutated strain of the Cordyceps fungus that has historically been used as a supplement, claiming to boost immunity and improve athletic performance. But now, researchers say that the fungus could be transmitted to humans, turning many of us into zombies.
You're a research assistant working in a locked, secure lab studying PS648 when some fungus infects your lab partner. Before your partner turns into a zombie, crack the code to escape the lab!
