My Doomsday Asylum

Delivery guy Ray Reynolds is reborn before the zombie outbreak. He spends 200 million to transform a Psychiatric Hospital into a Doomsday Fortress, stockpiling it with supplies and weapons. He sees through his childhood sweetheart's plot, drinks a Serum to gain the ability to control zombies, and after resolving the side effects, he kills Selina Sterling. He ultimately takes over the fortress to research the Cure, establishing a foothold in the Apocalypse.
