Thirty years ago, a game named Resident Evil ushered in the survival horror genre - a blend of nerve-shredding tension, elaborate puzzles, and intricate inventory management.
The series became Japanese developer Capcom's best-selling franchise ever, prompting books, films and TV programmes, as well as more games.
So how does the latest edition, Resident Evil Requiem - released to excited fans worldwide on Friday - keep the scares feeling surprising three decades on?
Koshi Nakanishi, who directed the new release, told the BBC the balancing act between "familiarity and freshness" had been a "huge challenge".
But he added he hoped the new title managed to "redefine survival horror in interesting new ways", while still "respecting the DNA of the series".
