Harmonix built a rhythm game about digging through a dead woman’s mind, and it wants you to play it with three friends on the couch. Amplitude is a reboot of the studio’s 2003 cult favorite, and it landed on PlayStation 3 and PlayStation 4 in 2016 as a licensed sequel — Sony Computer Entertainment owns the rights to Frequency and the original game, which is why the whole thing carries that particular smell of a passion project made under someone else’s roof.
It scored 7.8 out of 10 across six outlets in the IGDB critic aggregate. That number is about right, and the reasons are worth pulling apart.

Mari’s Brain Shuts Down in 2112
The setup is science fiction with a straight face. In 2112, nanotechnologists at the Applied Meta-Prionics Limbic Tuning Department create organic machines that can be inserted into the human brain to reach the physical and metaphysical secrets inside. One of the technologists, Mari, has synesthesia — the game calls it a “gift” — and she programs a new batch of bots to enter her own mind and unlock the enhanced visual and aural perception she was born with.
The flood of imagery and sound overwhelms her. Her brain shuts down.
You play as the AMPLITUDE Operating System, sent into Mari’s memories, senses and emotions. Your job is to blast away the protective scarification her brain built around those synesthetic senses and bring her back. Harmonix says the game is treated like a classic sci-fi concept album, with a narrative that runs through the visuals, music and lyrics rather than sitting in cutscenes.
That is a real idea, not a coat of paint. It is also the part of Amplitude that the track-blasting never quite earns.
Twenty Songs Built for Beatmatching
Amplitude ships with more than 20 songs composed for an optimal beatmatching experience, with contributions from Freezepop, Danny B and Jim Guthrie among others. Many of the developers who worked on the 2003 original are on the reboot.
The structure is unchanged at its core. Players speed down long, winding paths made up of a song’s separate elements. Each track carries one sound — synthesizers, drums, vocals, bass. Blast away the patterns of gems on a track and you release that element’s musical energy, rebuilding the hidden song piece by piece.
The loop is easy to pick up and difficult to master, which is Harmonix’s own description and also just true. Top scores are hard enough to be worth bragging about, and online leaderboards exist for exactly that.
Forge, FreQuency Mode and the Tunnel
Harmonix built a new engine for this one. It is called Forge, and the studio used it again for Rock Band 4.
Two additions matter more than the engine. The first is a FreQuency mode, which switches the nearly flat track layout into the tunnel approach from the original FreQuency. It is a nod to the lineage and a genuine change in how the note highway reads on screen.
The second is team play, suggested by Harmonix’s Pete Maguire and added late in development. Two teams — 2-on-2 or 3-on-1 — play a song without failing, and the mode accounts for the difficulty levels of everyone involved. That last clause is the important one. A rhythm game that lets a beginner and a veteran share a screen without either of them sandbagging the other is solving a problem most of the genre ignores.
Local support runs to four players, with power-ups in the multiplayer mix.
The Tracklist Is the Argument
Here is where Amplitude makes its case, and where it splits its audience.
- Freezepop’s contribution anchors the electronic end, the same territory the band worked in for the original.
- Danny B brings the chiptune and arcade instincts.
- Jim Guthrie supplies the moodier, more atmospheric material.
- The balance of the 20-plus songs is Harmonix’s own composition, written specifically for beatmatching rather than licensed and retrofitted.
That order is not a ranking of quality. It is a ranking of how much each name tells you about what the game sounds like before you press start. Freezepop tells you the most. Guthrie tells you the least, and does the most work in the back half of a session.
The concept-album framing means the tracklist is not a playlist. It is the score. Lyrics carry narrative. Visuals carry narrative. That is a harder trick than it sounds, because the player is staring at gems on four lanes and has limited attention left for storytelling.
Four Lanes, One Song, No Excuses
The moment-to-moment play is the strongest thing here, and it has not aged badly.
You are not playing a song. You are reassembling one. Each lane holds a single instrument or vocal, and clearing its gems brings that element back into the mix. Miss enough and the music thins out. The feedback is immediate and it is musical rather than punitive, which is the whole reason this formula worked in 2003 and works now.
The winding paths do more than look good. They force the eye to travel, and they make the flat-to-tunnel switch in FreQuency mode feel like a different game rather than a filter.
Difficulty scaling is honest. The ceiling is high, the floor is low, and the leaderboards give the high ceiling somewhere to go.
Where the Concept Album Springs a Leak
The narrative is the weak joint.
Mari’s story is delivered through visuals, music and lyrics, and that is a genuine formal ambition. It is also the least legible part of the package. A player deep in a four-lane run at speed is not reading lyrics for plot. The scarification metaphor — blasting away the protective shell her brain built — maps cleanly onto the mechanic of clearing gems to restore a song, and that mapping is clever. But clever mapping is not the same as a story you can follow.
The sci-fi concept album idea is the right idea. Amplitude does not fully deliver it, and the gap between what the game says it is doing and what a player actually absorbs is the single biggest reason this is a 7.8 and not higher.
Team play is the opposite story. It was added late, it was suggested by one developer, and it is the mode most likely to keep the disc in the tray. Cooperative-competitive play that respects mixed skill levels is rare, and Harmonix got it right on the first pass.
What 7.8 Actually Means Here
Six outlets averaged to 7.8. That is a score that says competent, distinctive, not essential — and for Amplitude, it undersells the multiplayer and oversells the story.
The reboot question is worth answering plainly. This is a sequel licensed by Sony, built by many of the same developers, using a new engine, with new songs and modern hardware features layered onto a 2003 design. It is a reboot in the marketing sense and a sequel in the legal sense, and neither label tells you whether to play it.
Play it for the four-player local mode. Play it for FreQuency mode if you remember the tunnel. Play it for Freezepop. Do not play it expecting the concept album to land, because it does not, and the game never quite admits that.
The score is 7.8 out of 10.
