From Ants to Zombies is a showcase for the remarkable range horror gaming has achieved, across six decades, from the 1970s to the 2020s, and over 70 hardware platforms, from the ZX Spectrum to the Xbox Series X. More than 130 horror titles are analyzed and contextualised across thirteen thematically-divided chapters, covering a variety of genres (from rail shooters to open-world RPGs), settings (from haunted mansions to infested space stations) and shades of fear (from creeping existential dread to stomach-churning outbursts of violence). The discussion is enlivened by exclusive commentary from pioneering horror developers such as Keiichiro Toyama (Silent Hill), Jane Jensen (Gabriel Knight), Ken Levine (System Shock 2), Sandy White (Ant Attack), David Riordan (It Came from the Desert), Paul Norman (Forbidden Forest), Graeme Devine (The 7th Guest), and many more.
