This Spring 2017, defend humanity from the Chimera Virus as the new leader of Japan’s covert military agency (ACID) in Dark Rose Valkyrie! Featuring work from “Tales of” scenario writer Takumi Miyajima and “Tales of” character designer Kosuke Fujishima, this real-time combat, action-packed RPG will have you battling enemies that change in form and strength as darkness sets. But that’s not all, a traitor is in your midst! Use a visual-novel interview system to find them out and strengthen the Valkyrie Force and save the world!

Key Features

• Take the fight into Overdrive! Characters can transform into their stronger split personalities mid-battle, but be strategic – too many transformations will lead to Fatigue!
• Customize Combos! Customize attacks for each character, and do more damage with Riot Combos!
• A Traitor Amongst You Depending on your choices, one team member will betray you. Find the traitor in visual-novel style interrogation sequences, and change the game’s ending!
