Glitched Legends Battle Finn

Review by eFreeware

The pitch for Glitched Legends Battle Finn is that the corruption has spread beyond its own cartoon cast. The developer has pulled in enemies from well-known video games alongside the usual Friday Night Funkin-style faces, so the roster is a mix of characters you might not expect to see sharing a chart. That crossover is the reason this mod stands apart from the many others built on the same rhythm formula, and it is the first thing I would point anyone toward.

It is a free download in the Music category from developer Phampham, rated Teen, and it has been installed more than 500,000 times since its release in August 2022. The average sits at 4.5 from 5,568 ratings, which suggests a settled audience rather than a novelty spike.

This is for people who already know the arrow-tapping format and want more of it with a darker, glitch-flavored theme. If you are new to rhythm games entirely, the tutorial week exists precisely to walk you through the basics before the difficulty starts climbing.

Tapping arrows while the corruption takes over

The core loop is the familiar one: arrows scroll toward a target and you tap in time to match them, and the closer your timing the higher your score. There is nothing to learn beyond that, which is exactly the appeal. The developer describes the design as simple and easy to pick up, and the difficulty curve is handled by the songs themselves rather than by any complicated system.

What the developer promises is a steady ramp. Each track is harder than the one before it, so the mod effectively teaches you its own patterns as you move through the set list. That structure rewards patience: a song that feels impossible on a first attempt tends to become manageable once your fingers know the shape of the chart.

Around the tapping sits the presentation. The backgrounds are described as high quality, the sound effects are meant to carry weight, and the music includes cg5 tracks. I would treat the visual side as the real differentiator here, because the corrupted versions of familiar characters are what give the mod its identity rather than the mechanics, which are shared with every game of this type.

Fourteen songs, six weeks and a freeplay shelf

The content count is the most concrete thing the developer offers: 14 songs spread across six weeks, with the tutorial counted as one of those weeks, plus two additional songs available in freeplay mode. That is a reasonable amount of material for a free mod, and the freeplay tracks give you something to return to once the main progression is finished.

The week structure matters because it groups songs into sets, so you are not scrolling through a flat list of unrelated charts. The tutorial week sits at the front, and from there the weeks presumably escalate in the same way the individual songs do.

On the enemy side, the roster includes Hypno, Lofi, twiddlefinger and silly billy, along with others drawn from popular games. The developer also mentions that the game is updated regularly, and the most recent update arrived in February 2026, so the set list has had room to grow since the original release.

Free to play, ads included

Glitched Legends Battle Finn costs nothing to download and carries ads. There are no in-app purchases, so nothing in the game is gated behind a payment and there is no shop to browse. The presence of ads is simply part of how the free version works.

For a mod of this size, that arrangement is straightforward. The trade-off is advertising. Anyone who dislikes ads in their rhythm games should weigh that before installing.

Who will get the most from this mod

The clearest audience is players who already enjoy Friday Night Funkin-style mods and have worn through the ones they own. Fourteen songs with a rising difficulty curve is enough to keep that group occupied for a while, and the crossover enemies give them something visually new even though the mechanics are familiar.

A second group is anyone drawn to the corrupted aesthetic itself. The idea of cartoon characters twisted by a spreading glitch, joined by villains from other games, is a specific flavor, and the mod leans into it through its backgrounds and character designs. If that theme appeals to you on its own, the rhythm game underneath is a serviceable vehicle for it.

The offline support broadens the appeal further. The game can be played anywhere without a connection, which matters for anyone who wants to fit a few songs into a flight, a waiting room or a long car ride as a passenger. Combined with the free price, that makes it easy to try without much commitment.

The Teen rating is worth noting for anyone installing on a shared device. The corruption theme and the glitch-styled characters are aimed at an older audience than a typical cartoon rhythm game, and the rating reflects that.

A free rhythm mod worth the download for the right player

Glitched Legends Battle Finn does one thing and does it without charging for it. The arrow-tapping loop is the standard one, the difficulty rises song by song, and the 14 tracks across six weeks plus two freeplay extras give you a real amount of material to work through. The corrupted crossover roster is what makes it memorable rather than just another entry in a crowded field.

The caveats are the ones that come with the territory. Ads are present, the format will feel familiar to anyone who has played this style of game before, and the appeal of the theme is doing a lot of the work. None of that is a problem if you know what you are getting.

I would suggest it to players who already like rhythm mods and want more charts with a darker visual identity, and to anyone curious about the corrupted-character concept who does not mind tapping arrows to see it. With a free download, no purchases and offline play, the barrier to trying it is about as low as it gets.
