Chaos Zero Nightmare Global is ready to enter into the RPG world with powerful combat, interesting characters and with a huge story as well. With a pre-registration going live, you must be excited to know what kind of game this is and what we will be getting as an overall. So, come, join and here is a Chaos Zero Nightmare overview guide with everything you must know.

Chaos Zero Nightmare Overview Everything You Need to Know

What is Chaos Zero Nightmare?

In Chaos Zero Nightmare, you will be entering Ark City, a simulated metropolis where your agents take on existential threats through looping chaos events. The game mixes roguelike exploration with visual novel-style storytelling, so you experience branching paths that dive into themes like trauma, choice, and redemption.

Battles are driven by deck-building, where each card represents an action, skill, or elemental affinity, giving you far more depth than a standard auto-battle system.

What is Chaos Zero Nightmare

A few standout features set the game apart are:

  • Trauma System: Every hit your agents take builds trauma. This can unleash powerful bursts in combat, but you'll need to manage the aftermath carefully once the fight is over.

  • Roguelike Exploration: Maps are procedurally generated, so every run feels different. You'll need to make adaptive choices, especially since there's no auto option during high-stakes challenges.

  • Single-Player Focus: There's no traditional PVP here. Instead, the game highlights progression, farming, and story depth, which keeps it engaging without making it overly grindy.

  • Platform Availability: You can play on iOS, Android, or PC through the Stove launcher.

Getting Started: Account and Progression Basics

When you first log in, you'll set up your Captain profile, which represents your account level. The cap is 60, and every ten levels, you'll face promotion missions that unlock new content. To move forward, you'll need to progress through the story, collect materials, and upgrade your facilities.

At the start, you'll follow through levels 1 to 10 with simple missions and daily logins. Running simulations helps a lot here, and each promotion tier opens up a new Chaos Zero Nightmare gameplay, such as advanced Chaos zones at level 20.

Stamina is your main resource, and it recharges naturally over time. You can also refill it through the Garden Cafe, which gives a free daily pot. Always put stamina toward simulations first since they provide XP and breakthroughs that speed up progression.

While guilds aren't available at launch, you can still add friends. Doing so gives you small perks like shared gifts and extra support in your runs.

Chaos Zero Nightmare Characters and Team Building

Combatants are set as the core of the Chaos Zero Nightmare squad. You'll get them through banners or by progressing in the story. Each one belongs to a class, has an ego attribute (element), and comes from a specific faction. These traits affect their synergies, so building a team in this game isn't just about raw power but also about pairing the right elements and factions together for stronger results.

  • Kayron (5★, Instinct/Controller, Unknown): A control expert who stacks debuffs that amplify stagger bars, giving your team more opportunities to strike.

  • Orlea (5★, Void/Vanguard, Enforcer): A frontline defender who absorbs trauma and turns it into shields to protect allies.

  • Mika (4★, Passion/Controller, Wanderer): A supportive healer with skills themed around guilt, restoring HP through affinity matches.

Leveling and Upgrades

Progressing your Roster in Chaos Zero Nightmare will require more investment, so for now, here is how the leveling system works:

  1. Basic Leveling: Use XP from Simulation Growth nodes to raise levels. You'll hit caps at 10, 20, and 30, which require breakthrough materials to push further.

Leveling and Upgrades

  1. Manifest Ego: Fuse duplicates to raise star levels, unlocking ultimate skills at higher tiers. You can farm shards later through Memory Fragments in Simulation.

  2. Potential Tree: Spend currency to unlock permanent skill boosts, like extra crit damage or defense. Prioritize offensive nodes for strikers and survivability nodes for vanguards.

Leveling and Upgrades

  1. Save Data Sets: Gear loadouts earned from Chaos clears give mode-specific buffs. For example, equip trauma resistance for roguelike runs.

Partners and Deck Building

Partners will act like modular weapons in the Chaos Zero Nightmare game, where you can attach them to your combatants. They don't take squad slots, but they still provide valuable skills, as shown in the released game footage.

Partners and Deck Building

So far, according to the details we have, there are multiple traits you must consider when dealing with partners as follows:

  • Assignment: Attach a Partner to a matching class or attribute for extra bonuses, like giving a Passion Striker faster attack speed with a Fire Partner.

  • Leveling: Partners use their own XP from Simulation nodes, which can be raised up to level 50.

  • In-Combat Use: Their skills charge as you play cards, letting you deploy effects like shields or healing bursts when needed.

Deck Building

Your deck will be acting as another core element of combat in Chaos Zero Nightmare, and it holds between 20 and 30 cards. You can expand it by researching in Ark City.

  • Card Types: Attacks deal damage, Supports heal or buff, and Controls apply debuffs. Each character also adds unique cards that give your deck more variety.

  • Epiphanies: Occasionally, cards glow and can transform into stronger versions. For example, a basic attack may evolve into a powerful elemental strike. Choose carefully since these can turn the tide of battle.

Battle System Overview

The combat in Chaos Zero Nightmare is going to run on a turn-based card system that keeps you on edge, so it never feels like an endless auto-battle.

You can draw five cards each turn and can only play as many actions as your current limit allows, starting at three and increasing with upgrades. Enemies have countdowns on their moves, which means you need to pace your plays carefully.

Battle System Overview

Every hit and debuff will fill your Trauma Bar. Once it's full, your character enters a break state, giving you a powerful ultimate at a lower cost. The catch is that the character becomes locked until you play five of their cards. After fights, you can either visit the Epion Center to gain affinity and keep your loot or wipe memories instantly, which clears progress but costs you the rewards.

Breaking enemy stagger gives bonus damage, while targeting red weakness icons multiplies your hits by 1.5. Your squad also shares one health pool, so when it hits zero, everyone becomes more vulnerable to trauma. To play smart, save your partner skills for enemy bursts.

Game Modes: From Story to Endgame

The game blends quick daily tasks with tougher challenges for long-term progression. And the different game modes that we will be getting are:

  • Ark City: Ark City works as your daily hub. You can spend just a few minutes raising affinity through gifts or conversations, setting policies with trade-offs like earning more currency but lowering work output, and upgrading city facilities such as Research for extra deck slots or Diners for buffs and potions. Shops let you trade city coins for essentials.

Game Modes: From Story to Endgame

  • Simulation: Simulation runs are where you spend stamina to farm materials like XP, breakthroughs, and potential currency. As you raise your Captain rank, more nodes unlock, including challenges and memory shards.

  • Missions: Missions cover both story and battle objectives. Battle missions are great for auto-farming once you hit three-star clears, while story missions combine visual novel elements you can skip after the first read. Promotions are often tied to clearing these.

  • Observations: Observations mode offers a roguelike adventure where you move through maps filled with fights, rests, shops, and events. Branching paths and campfire saves add variety, but going in underleveled often means restarting.

  • Chaos Zone: Chaos Zones form the endgame with escalating planet maps. The gear you earn here can be saved as loadouts, and you're encouraged to push for high scores.

For consistency, dailies include managing policies, raising affinity, and grabbing a free Cafe pot. Weeklies often come down to completing a full Chaos run.

Banners, Gacha, and F2P Tips

For the Chaos Zero Nightmare launch, there will be choice lead pulls, and a total of 3 will be released with the game:

Banners, Gacha, and F2P Tips

  • Beginner Banner: The beginner banner guarantees a five-star within 30 pulls at a discounted Ether cost. It's also where you can test different character kits without much risk.

  • Standard Banner: The standard banner has a 60-pull pity system and pulls from the permanent pool, which includes characters like Veronica and Orlea. The overall chance of pulling a five-star here is 1.5 percent.

  • Limited Banners: Limited banners work differently because they focus on specific five-star debuts, such as Rin, without diluting the pool. Each limited banner has its own pity system, separate from the standard one.

Free to Play Roadmap

As a free-to-play player, you can claim your pre-registration rewards and then use up your beginner pulls and push through missions until you reach Captain level 20. During the first week, you can go for farming Simulation runs to reach two or three promotions and build affinity with your main characters. Over time, saving about 180 pulls each month will allow you to hit pity when needed. Early on, prioritize Void characters since they perform well in Chaos zones.

If you're someone who spends, you can aim for milestone selectors rather than scattering your pulls across duplicates. It gives you more value in the long run. Be careful with trauma management at the start since counseling slots are limited, and keep an eye on seasonal balance changes since they often shake up the meta.
