A series of point and click/role playing computer games based loosely around the Cassandra Peterson character Creator/{{Elvira|MistressOfTheDark}}. In 1990, HorrorSoft Games released the first installment, ''Elvira: Mistress of the Dark''. The game was surprisingly well received by critics and adventure/horror fans, and in 1992 the follow-up, ''Elvira II: The Jaws of Cerburus'' was released to even better reviews than the original. In addition to being surprisingly good, the games were also known for being [[TrialAndErrorGameplay ridiculously]] [[NintendoHard challenging]] and ridiculously frightening, while maintaining a dark, tongue-in-cheek sense of humor. Not surprisingly, the majority of laughs came from Elvira's [[DeadpanSnarker comments]].

An [[SpiritualSuccessor almost identical]] IP from the same company, ''VideoGame/WaxWorks'', was released in 1992.

!!Tropes within the game include:

* AbsoluteCleavage:
* TheChewToy: If you are a gore fan, the protagonist, as you can let him die in a lot of gruesome ways.
* EyeScream: You can die with your eyes torn out by a hawk, you can get them fried, you can get one of them burned by acid...
* InventoryManagementPuzzle: Not only in the second game you can carry a limited weight, but many items will be damaged or destroyed under certain circumstances (like being struck by fire, falling into a trap or going underwater). This obviously includes [[{{Unwinnable}} one-of-a-kind items you need to beat the game]], [[GuideDangIt if you haven't wasted them on preparing a non-essential spell before]]. A cautious player will know to leave important items in central hub rooms where they can pick them up only when they're needed.
* FanDisservice: At one point in the haunted house, you can join a lovely young woman in bed. Is it sexy? At the beginning, yes. At the end? '''''HELL NO.''''' There's a reason one Website/YouTube comment referred to the woman as [[spoiler: "Lamprey head"...]]
* GiantSpider: There's a gigantic black widow in ''Elvira II''.
* GuideDangIt: In Eivira II, you have limited resources to cast a wide array of spells, without many clues about how many casts of each ones you'll need to complete puzzles and evade traps. If you use up critical components for the wrong spells, the game becomes {{Unwinnable}}
* HaveANiceDeath: The games seemed to take a sadistic pleasure in showing the player gruesome death screens depending on how and where they were killed.
* TheManyDeathsOfYou: '''''Boy howdy.'''''
* NintendoHard: For starters, strategy guides straight up recommend reloading if you get hit once, because healing items are ''that'' rare.
* NonCombatEXP: ''Elvira 2: Jaws of Cerberus'' grants you experience for going into unexplored map squares and casting spells. Technically, you could get unlimited experience by preparing and casting a lot of free spells (but you'd have to wait for your Power Points to regenerate, so it would take a ''long'' time.)
* PossessionImpliesMastery: Zig-zagged in the first game. You can arm yourself with a crossbow, but you'll always miss the target. However, after managing to hit the bullseye of a practice target with only ''four'' shots, you'll be called a "master bowman" and become able to use it.
* PerversePuppet: If one of the books you find in the library of the Haunted House in the second game is by any indication, all the monsters you fight through the game are animatronic puppets created by the studio´s crew that have become sentinent and turned evil, including Cerberus.
* PotionBrewingMechanic: In ''Mistress of the Dark'', you can create magical potions by combining various ingredients you found. For example, consuming Herbal Honey gives you knowledge of the true names of all plants and eating Alphabet Soup gave you knowledge of Runes.
* RegeneratingMana: ''Elvira II: Jaws of Cerberus''. Power points replenish themselves automatically over time, though very slowly.
* SavageWolves: That can eat your neck.
* SchrodingersGun: In the second game there are three places where Elvira may be hidden; no matter in what order you reach them, the first two Elviras will be fake and transform into monsters.
* TrialAndErrorGameplay
* UnwinnableByDesign / UnwinnableByMistake: Even if you ''do'' avoid the many, many pitfalls, you might still lose something vital in a fireball trap.
* YourHeadAsplode: The witch you encounter early on in ''The Jaws of Cerberus'' goes down like this. Complete with her one eyeball flying toward the screen!
