Zombie Flesh Eaters (1979)

After an abandoned boat sails into New York harbor with a zombie aboard, a reporter teams up with the daughter of the boat's missing owner to investigate the island where he was last seen conducting research—the site of an alleged zombie outbreak.

Zombie Flesh Eaters keeps every mind human — it fights its subject at zero distance. The story fights on E6/E9 of the E0–E14 reality ladder, compressing fear, survival, infection, death, panic.
