Launch Trailer, Steam and Gameplay

Fanatical Cuts the Price by 96%
The latest discount is the main reason Phantom Breaker: Omnia has resurfaced in September 2026.
Game*Spark reports that Fanatical's Japanese storefront is offering the Steam version for ¥92, compared with a regular price of ¥2,300.
That works out to a 96% discount.
Fanatical pricing varies by region. During the same verification period, price tracker GamerPoint showed the US offer at US$0.79 instead of US$19.99, also representing 96% off.
Game*Spark lists the deal as running until September 29 at 7:59 AM JST. Fanatical also notes the possibility of keys selling out, meaning the stated end time does not guarantee stock until the final minute.
The product being sold is a Steam key through Fanatical, rather than a direct Steam Store discount.
The 20-Fighter Roster Includes Kurisu Makise and Rimi Sakihata
One of Omnia's most recognizable roster features is its Science Adventure crossover.
Kurisu Makise from Steins;Gate is a fully playable guest fighter. She is joined by Rimi Sakihata from Chaos;Head.
The two appear alongside returning fighters from Phantom Breaker: Extra and two characters created specifically for Omnia, Artifactor and Maestra.
Rocket Panda Games lists 20 playable characters in total.
Kurisu and Rimi are not simply visual cameos. Both are integrated into the actual fighting roster with movesets built for Phantom Breaker's battle system.
That makes the extremely low sale price potentially relevant even to Steins;Gate or Chaos;Head fans who have never previously followed Phantom Breaker itself.
Quick, Hard and Omnia Change How Each Fighter Plays
Character choice is only one layer of the battle system.
Players also select one of three fighting styles before a match.
Quick emphasizes speed and combo flexibility.
Hard leans more heavily into damage output and specific defensive mechanics.
Omnia provides a third approach built around more accessible inputs and a different meter system. Game*Spark notes that the style simplifies access to techniques, while its meter can build as high as 400% for dedicated moves.
This means the same character does not always need to be approached with an identical tempo.
Rocket Panda Games also says Omnia's overall combat system was retuned and rebalanced from Phantom Breaker: Extra, making combos and special attacks easier to execute.
Omnia Is a Major Upgrade to Phantom Breaker: Extra
Phantom Breaker: Omnia did not arrive without a history behind it.
Rocket Panda Games describes the release as a massive update to Phantom Breaker: Extra, the 1-vs-1 fighter originally released by MAGES in 2013.
Omnia carries forward story material from Phantom Breaker and Phantom Breaker: Extra while adding characters, balance changes, updated artwork and presentation, and a modernized audio package.
For the first time in the Phantom Breaker series, the full roster received English voice acting, while the Japanese voice track remained available.
Each character's music was also remixed, with an option to switch back to the original background tracks.
Omnia is therefore better understood as a comprehensive modernization of the earlier fighting game rather than a straightforward port.
Phantom Can Grant a Wish, but the Battles Have Another Purpose
The story takes place in Tokyo and revolves around a mysterious figure known as Phantom.
He approaches young fighters and gives them supernatural weapons called Fu-mension Artifacts. In exchange for fighting one another, Phantom promises that whoever survives can have their greatest wish granted.
The clashes between those artifacts have a hidden consequence.
They create distortions in space-time that weaken the boundaries between parallel universes.
If those boundaries collapse far enough, they could break the seal suppressing Phantom's own destructive power.
Story Mode presents that conflict from different fighters' perspectives, giving the roster a narrative role beyond Versus and Online play.
Steam Is Only One of Several Platforms
Phantom Breaker: Omnia launched worldwide in March 2022.
Alongside Steam, it is available on PlayStation 4, Xbox One and Nintendo Switch.
Steam lists MAGES. Inc. and GameLoop Inc. as developers, with Rocket Panda Games serving as publisher outside China.
The PC version includes single-player, online PvP, shared/local PvP, Steam Cloud, achievements and Family Sharing.
A Steam demo is also still available for players who want to test the combat system first.
The 96% promotion discussed here, however, specifically applies to the Steam key sold through Fanatical rather than every console version.
Why This Matters
1) The entry price is exceptionally low
The reported ¥92 Japanese price is dramatically below the cited ¥2,300 regular price.
2) The roster crosses over with Science Adventure
Kurisu Makise and Rimi Sakihata give Steins;Gate and Chaos;Head fans an additional reason to check out the fighter.
3) Three styles add variety without changing characters
Quick, Hard and Omnia can alter speed, power, mechanics and resource management for the fighter being used.
4) This is more than a simple rerelease
Omnia rebalances the fighting system, adds two characters, includes dual-language audio, remixes its soundtrack and packages story material from Phantom Breaker and Extra.
