However, as an open-source game, the game is quite easy to customize and mod, leading to countless mods of the game being made over the past year. These mods come in all shapes and sizes, adding custom music and animations. Many of these mods truly push the difficulty of the game to another level and are quite difficult for even the most seasoned players. So today we’re going to shine a light on ten of the most unforgiving and difficultFriday Night Funkin’mods you can currently play!
Updated on June 11, 2025, by Paul DiSalvo:ThoughFriday Night Funkin’s Kickstarter was able to generate an impressive two-million dollars, it’s been several months since the game received an official update. Luckily, due to the game’s open-source nature, fans of the game will have no shortage of content to play while they wait for additional official updates, as fan-made content is generated in massive quantities. As various mods focus on pushing different elements of the game such as what can be done visually or within the game’s mechanics, it should be no surprise that several mods aim to push the envelope regarding FNF difficulty.
13Vs Zardy
Only a single song, theVs. Zardymod features a much longer track than players are used to, going for over four straight minutes while most tracks tend to be under two minutes long. While the track starts off quite straightforward, it continuously grows in difficulty, allowing it to serve as an excellent endurance test for players.

12Mid Fight Masses
Mid Fight Massesis a mod that features high-quality music and animation, receiving several updates to provide it with additional gameplay polish. Of the mods on this list,Mid FIght Massesfeatures difficulty that feels the most in line with the most difficult songs currently in the main game.

While the first two tracks, Parish and Worship are quite manageable for intermediate-level players, the latter songs of this mod are much more likely to give players trouble. Luckily, each track in this mod is musically a slam dunk, so needing to re-listen to these songs is far from terrible.
11Tabi Genocide Retrospecter Remix
Vs. Tabiis a well-known FNF mod that’s highly regarded for its high-quality music, animation, and its inclusion of voice acting. WhileVs. Tabiisn’t the most difficult mod around, it has been remixed in the form ofTabi Genocide Retrospecter Remix,a mod that is effectively a mod of a mod With remixed versions of the songs of the originalVs. Tabi,this mod feature’s several difficult and quick charts that can be difficult for the most experienced of players.
10Vs Bob
Vs. Bobis a mod that has all of its difficultly backloaded into the last of its three songs. While the first two tracks of this mod are rather comedic and far from difficult, the mod’s third track is a completely different story.

Featuring imagery and elements that one would expect from a horror game, this final discordant song features a notably fast speed and an absurd amount of arrows, requiring a great deal of precision. While this song would already be quite difficult for veterans of the game, it features an added element that frequently blacks out a player’s screen, effectively requiring them to temporarily continue playing while blind.
9Tricky
Known simply as the Tricky mod, this mod has the player square off against Tricky the clown from the Newgrounds game,Madness CombattoFriday Night Funkin'.Featuring fully animated cutscenes and receiving a major update, the difficulty of the first song in the mod is in line with Week 7 of the core game. However, the second song of the mod, Madness, quickly ramps up the difficulty and increases the tempo.
The third track in this mod, Hellclown really ramps up the difficulty by uniquely including several notes that are meant to be intentionally missed, while the final track of the mod expands upon this concept and throws additional distractions at the player alongside another already difficult song.
8SiIvagunner
For those unaware, SiIvagunner is a youtube channel based around creating edits or “rips” of various songs from video games, remixing and editing them to sound like other songs, most often for the sake of comedy. As the channel has been releasing edits and rips ofFriday Night Funkin’songs, these edits have been made fully playable in a dedicated mod.

Despite many of the songs being based around jokes, the mod is no laughing matter, featuring incredibly difficult hard mode versions of songs as well as challenging remixes of the available tracks.
7Bob’s Onslaught
Featuring everything from fart sound effects to the Taco Bell sound effect, on paper this Microsoft Paint art and meme-filled mod is far from the most serious entry on this list. While not the easiest mod on the eyes or ears, the difficulty of the second and third tracks of this mod offer a notable difficulty level, with the third track even offering added difficulty through several visual distractions over the player’s arrows.
6X Event
X Event is a mod that features characters, aesthetics, and sound effects found within the indie RPG,Undertale. However, rather than simply featuring preexisting music from Undertale, this mod features entirely original music. Similar toTrickyandMid Fight Masses,the first track of this mod features difficulty that feels at home within Week 7 of the core game ofFriday Night Funkin',but quickly escalates in difficulty.
In addition to the latter two songs of this mod being quite difficult, likeZardy,they are on the longer side, so they truly test the endurance of players.
5Dark Sheep
Rather than focusing on the player’s opponent, theDark Sheepmod experimentally features a plain black background and puts the full focus on the gameplay. Moving around the gameplay interface to the beat of the song,Dark Sheepcan be quite disorienting and hard to keep track of, adding an additional layer of difficulty. While this change in visual style and the interface is strenuous enough to deal with on its own, the music ofDark Sheepis no cakewalk.
4Shaggy
While the Shaggy mod, featuring Shaggy fromScooby-Doois indeed ahilarious meme in itself, it is an incredibly difficult mod that throws many unexpected obstacles at the player. While things may seem simple at first, simply featuring a hilarious remix of theScooby-Dootheme song, as the mod’s difficulty rapidly progresses.
While the second song is quite manageable as well, the third and fourth tracks throw a devastating curveball at the player byforcing the need to use several additional keys, becoming more arduous through added complexity.
