Horror games are built to unsettle, using dread, isolation, and the threat of the unknown to keep players on edge. Whether you're surviving the night in The Forest, fending off the undead in Left 4 Dead, or scavenging through the bleak countryside of Project Zomboid, the genre thrives on tension and vulnerability. Expect limited resources, eerie atmospheres, and moments designed to make your pulse spike when something finally lunges from the dark.
