Featuring the talents of Tales of series scenario writer Takumi Miyajima and Tales of series character designer Kosuke Fujishima, this JRPG appoints you to lead an elite military force known as ACID (Anti-Chimera Interception Division) to defend humanity from enemies transformed by the mysterious Chimera Virus! Fight in a real-time battle system alongside your teammates--but don't let your guard down. Investigate your allies to expose the traitor infected by the virus, before it's too late!
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 weapons and attack combinations for each character, and do more damage with Riot Combos, Simultaneous Attacks, and more!
A TRAITOR AMONGST YOU!
Depending on your choices, a team member will betray you. Find the traitor in visual-novel style interrogation sequences, and change the game’s ending!
