Smilegate, in partnership with developer Super Creative, has officially launched Chaos Zero Nightmare, a visually striking dark fantasy roguelike deckbuilder RPG, now available free-to-play on PC via STOVE, iPhone via the App Store, and Android via Google Play.
Since its pre-download phase began on October 21, Chaos Zero Nightmare has stormed to the No. 1 spot in the Apple App Store’s free download charts across major regions, including the U.S., Canada, Japan, Korea, Hong Kong, Taiwan, Singapore, and Macau, signaling a massive global debut for Smilegate’s latest franchise.
A Roguelike Deckbuilder with a Psychological Twist
Chaos Zero Nightmare fuses roguelike progression, deckbuilding strategy, and RPG storytelling in a world teetering on the edge of madness. Players take on the role of a Protos, an anomaly capable of retaining memories amid a collapsing world corrupted by the cosmic force of Chaos. Joined by a cast of partner agents, players will descend into eldritch environments, battle horrifying abominations, and endure mental breakdowns as they struggle to survive.
The game features a deep combat system built around customizable decks, synergies between agents, and the mental states of each character, where madness and strategy intertwine.
