Arbiter is the new game by the developer of RWBY: Grimm Eclipse. In Arbiter, players take on the role of Ashe, who has been given great powers from the spirits Dove and Raven, and will have to use them to battle escaped evil beings using an Ikaruga-like dark/light mechanic.
Players will be swapping from dark and light forms in the midst of combat, to deal with the game's dark and light spirits. These evil creatures are divided into dark and light monsters, and can only be harmed by the opposing type. In keeping with that, both enemies and Ashe will absorb damage from the same type, so the game will require stance swapping in order to do damage and regain lost health.
Players will also have access to an array of light and heavy attacks, special abilities gained from beating bosses, and dodging techniques to make it through. They'll use these powers over a large variety of worlds, gaining energies they can channel into upgrading Ashe as they go.
Arbiter is being developed for PC. You can watch the announcement trailer below.
