In a surprising twist that Mario fans never expected, Nintendo’s green-clad brother steps into the spotlight as the protagonist of a terrifying fan-made horror game called Crucis Mortem. This indie creation transforms the cheerful world of Super Mario into a nightmare landscape where Luigi must survive against corrupted versions of familiar characters.
Crucis Mortem is a 2D horror fan game created by WhiteVoid, based on Super Mario Bros 2, where Luigi must survive a corrupted, glitched version of the game. The Latin name translates to “of the cross” or “of the dead,” perfectly capturing the game’s themes of death, corruption, and religious horror imagery that permeates every pixel of this unsettling adventure.
What makes this fan creation particularly compelling is how it reimagines the whimsical Mushroom Kingdom as a place of genuine terror. As someone who has followed indie game development for years, I’ve seen countless Mario fan games, but few have successfully captured the essence of horror quite like this one. The community response has been overwhelming, with multiple YouTube playthroughs garnering over 150,000 views each and fans creating theories about the deeper meaning behind Luigi’s journey.

Crucis Mortem represents a fascinating entry in the Mario horror subgenre that has grown increasingly popular among indie developers. Created by WhiteVoid for the Luigikid EXE Challenge 2 in December 2022, this game demonstrates how fan creativity can transform familiar franchises into something entirely new and unexpected.
The game was developed using Game Maker Studio, a popular choice for indie creators working on 2D projects. WhiteVoid participated in the Luigikid EXE Challenge, which encourages developers to create horror games based on popular characters, resulting in this unique interpretation of the Mario universe with a psychological horror twist.

For those interested in similar indie game guides that explore unique gaming experiences, the indie scene continues to produce innovative horror content that pushes boundaries.
The game’s premise immediately establishes a dark atmosphere that contrasts sharply with typical Mario adventures. Luigi finds himself trapped in a corrupted version of the Mushroom Kingdom, where familiar locations have become twisted nightmares and beloved characters have transformed into grotesque parodies of their former selves.
The psychological horror elements emerge through glitch effects, distorted environments, and the gradual revelation that something terrible has happened to Mario and his friends. Players piece together the story through environmental details and brief encounters that suggest Luigi may have “committed” some unspeakable act that led to this corruption.
This narrative approach creates genuine tension and mystery, leaving players to question what’s real and what’s just part of the game’s unsettling atmosphere. The horror doesn’t rely on jump scares alone but builds a pervasive sense of dread through its corrupted aesthetic and the implications behind each grotesque character design.
The character designs in Crucis Mortem represent one of its most impressive achievements, transforming Nintendo’s iconic cast into genuinely disturbing figures that maintain enough familiarity to be recognizable while becoming truly terrifying.
| Character | Role in Game | Horror Elements | Design Inspiration |
|---|---|---|---|
| Luigi | Protagonist/Survivor | Traumatized, fearful | Classic Luigi design with terror expressions |
| Mutkifer | Primary Antagonist | Corrupted Mario with mutated features | Mario.EXE creepypasta influences |
| Toadkif | Secondary Threat | Distorted Toad with unsettling proportions | Classic Toad design with horror modifications |
These character designs show remarkable attention to detail in how they corrupt the familiar while maintaining enough recognizability to be effective horror elements. The community has particularly praised Mutkifer’s design as a successful interpretation of what a corrupted Mario might look like in a horror context.
The connection to classic platformer games remains evident in the character movements and interactions, creating an interesting contrast between the familiar gameplay mechanics and the terrifying presentation.
Crucis Mortem combines traditional platforming elements with horror mechanics to create a unique gameplay experience that feels both familiar and unsettling. The controls are simple and responsive, allowing players to focus on the atmosphere and narrative rather than complex mechanics.
The gameplay strikes a careful balance between frustration and fear, though some community members have noted that certain sections become more challenging than scary. This tension between difficulty and horror is a common challenge in indie horror games, and overall, Crucis Mortem manages to maintain its atmospheric effectiveness despite occasional difficulty spikes.
The response to Crucis Mortem has been overwhelmingly positive within the gaming community, particularly among fans of indie horror and Mario creepypasta content. YouTube playthroughs have generated significant engagement, with viewers expressing genuine shock at the game’s effective horror elements and impressive atmosphere for a fan-made project.
Community feedback highlights include praise for the game’s visual design, successful creation of tension through limited visibility and chase sequences, and appreciation for how it transforms familiar characters into genuinely frightening figures. Many players have reported experiencing real jump scares, particularly during encounters with Mutkifer.
