Phantom Breaker: Omnia is a 1-on-1 fighting game featuring 20 characters, each with 3 fighting styles. Omnia is the first mainline game in the series to make its way to the west, with the original North American Xbox 360 release never materialising.
In story mode, a mysterious man known as "Phantom" appears in Tokyo. He bestows multiple teenagers with powerful weapons known as "Fu-mension Artifacts", manipulating them to fight by promising to grant any wish to the victor.
Of the 20 characters featured in Phantom Breaker: Omnia, there are 2 guest characters from the Science Adventure series — Rimi Sakihata and Kurisu Makise. 2 other characters, Artifactor and Maestra, are also brand new to this version of Phantom Breaker. Each character is voiced with both the original Japanese dialogue and new English voice acting.
