Chaos Zero Nightmare is a role-playing game from Korean studio Smilegate, the developers behind other successful RPGs like Epic Seven and Lost Ark, which combines a dark adventure with anime aesthetics, with a combat system very similar to the great Slay the Spire. The result is a title with a deep story full of interesting characters, which you can progress through little by little by making a series of decisions.

Stove, the launcher you need to play

If you want to play Chaos Zero Nightmare on PC, the first thing to keep in mind is that you will have to install the official Smilegate launcher, called Stove. This launcher provides an easy way for you to download this game and other titles developed by the company. To use it, you need to create a user account. You can use an email address, Facebook account or Google account. By doing so, the launcher will be perfectly configured and ready to work in under two minutes.

A dark and violent story

Despite its sometimes colorful and cheerful anime aesthetic, the tone of the game is decidedly sinister. The game presents Planet Earth practically reduced to rubble, and some of the mechanics that you can experience during combat will make your characters lose their sanity, giving the whole adventure a dark tinge. Even the character designs themselves are very disturbing, especially when it comes to some of the more dangerous bosses in the game.

Roguelike deckbuilder-style combat

In Chaos Zero Nightmare, the combat will feel very familiar to anyone who has ever played a roguelike deckbuilder. The main difference between this and Slay the Spire is that, instead of controlling a single character, you lead a group of three. You can combine their abilities, adding an additional strategic element to the game, which allows you to create synergies between their attacks. The core of the game, however, remains virtually identical: you have a limited number of energy points per turn-based round, which you can use to play your cards and finish off your enemies before your characters are defeated.

Recruit new heroes for the group

As is typical of almost any modern free-to-play RPG, Chaos Zero Nightmare features a gacha system to recruit new heroes for your party. You can collect dozens of different characters, each with their own design and special abilities. Some legendary characters also have unique interactions and very powerful combat cards. At some points in the game, you can chat with the different characters in your group and strengthen ties with them.

Spectacular roguelike deckbuilder for PC

Download Chaos Zero Nightmare and discover a spectacular role-playing game, which not only stands out for its beautiful graphics and anime aesthetics, but also for its solid and engaging combat system. Though the campaign lasts around 12 hours, you can dedicate much more time to this outstanding title thanks to the procedural missions and seasonal events.
