Select the 2-player mode to start playing. Welcome to marios.games, your ultimate hub for classic and community-created Mario adventures! If you thought you knew everything about the classic Super Mario Bros. (1985), think again. Mario '85 (originally developed as MARIO.EXE or PC Port) turns nostalgia on its head, delivering a tense, atmospheric psychological horror survival game built on the skeleton of the classic NES platformer.
Mario '85 is a famous horror fan-game inspired by retro creepypasta lore. Instead of playing as the iconic hero Mario to rescue Princess Peach, you play as Lucas (a version of Luigi), who finds himself trapped inside a cursed execution of the 1985 arcade classic.
In this twisted realm, Mario is replaced by MX—a towering, monstrous entity with hollow black eyes and a permanent, sinister grin. MX stalks you relentlessly through corrupted levels, seeking to crush Lucas and claim his soul forever.

Mario '85 took the indie horror scene by storm for several key reasons:
Subversion of Nostalgia: It takes the comforting, familiar physics and aesthetics of Super Mario Bros. and distorts them into an oppressive nightmare.
Dynamic AI Pursuit: Unlike standard retro games with fixed enemy patterns, MX actively stalks you with relentless velocity, forcing high-pressure platforming.
Friday Night Funkin' Exposure: The character MX gained massive viral popularity after being featured in high-profile Friday Night Funkin' (FNF) mods like Vs. Sonic.exe, introducing millions of players to the original game's lore.
Flawless Pixel Art & Sound Design: The retro 8-bit visual style combined with unsettling industrial audio cues creates a genuinely terrifying atmosphere without relying solely on cheap jump scares.
Unlike traditional platformers like Super Mario World or Super Mario 64, Mario '85 flips the core objective from exploration to pure survival.
The Monstrous Stalker (MX): MX cannot be defeated by stomping or fireballs. He breaks through blocks, ignores level obstacles, and grows faster as you progress.
Inverted Mechanics: You aren't hunting for coins or power-ups; you are running for your life while managing limited stamina and tight platforming timers.
Psychological Dread: The haunting music distorts, the background visuals glitch into horrifying landscapes, and ambient sound effects keep you on edge at every jump.
High Stakes: Catching one mistake usually results in a brutal execution screen, making every jump in level World 1-1 feel like a high-wire act.
Select the 2-player mode to start playing. The gameplay is designed to test your precision platforming under extreme panic.
Navigate through corrupted stages, dodge hazardous traps, and reach the pipe at the end of each stage before MX catches you.
