The grimdark concept has been around since Warhammer 40,000 popularized it in the 1980s. Now, it's being applied to the fantastical realm of anime ARPGs with Chaos Zero Nightmare. You won't have to wait long for this nightmarish RPG, as it launches on October 22nd!
In Chaos Zero Nightmare, you lead a diverse cast of anime girls in combat against The Blue Pot. Although the name might not sound threatening for a pervasive evil, it's no laughing matter.
Chaos Zero Nightmare distinguishes itself not only with waifus and ARPG gameplay but also with extreme brutality. While it's not Mortal Kombat, your agents risk being torn apart in every mission, silhouetted or not. It's a far cry from Genshin Impact.

Beyond its new mechanics, Chaos Zero Nightmare also features card-based roguelike combat and impressive animation. While it may not appeal to those who dislike anime art, it offers a dose of seriousness for fans seeking more gritty animated action.
Of course, as a late September announcement, Chaos Zero Nightmare will be showcased at the 2025 Tokyo Game Show. Watch for hands-on demos, cosplayers, and other on-site events.
