After a couple of trailers, Augmented Reality Girls Trinary went quiet after showing off its private chat and event scenes interaction feature. After a month of no news regarding the game, Gust finally posted a new trailer highlight its battle system, which is rather interesting, to say the least.
The battle system seems to be a mix between 3D and 2D battles, where the heroines are rendered in 3D fighting against 2D illustrated enemies. Incredibly stylised, the battle is somewhat reminiscent to the likes of the modern Persona games with a bit of Fate/Extra.
Be sure to run through the character trailers once more in case you missed them:
