Capcom's Resident Evil set the style for survival horror in almost every aspect, codifying elements of the genre from level and sound design, gameplay mechanics, and, of course, to the menagerie of creepy and deadly creatures that threatened to end the protagonists at every turn. Resident Evil's penchant for disturbing and dangerous enemy design has a strong history, and many of its monsters have reoccurred across the breadth of the franchise, often in increasingly more elaborate and murderous incarnations.
