Chaos Zero Nightmare Gameplay Guide

 

Since you are dealing with a time-sensitive, card-based gameplay, you need smoother performance to make every move count for winning battles. That’s why you can use OSLink for support. It lets you run the game on your PC to handle heavy processing while you play remotely from your mobile, ensuring no lag and perfect timing for your card management. So, let’s dive into the guide:

Understand Chaos Zero Nightmare Gameplay

When you start playing Chaos Zero Nightmare, it’s important to understand how the gameplay works. The game is built around cards and turn-based battles, where every move depends on how effectively you play your cards. Your strategy and timing determine your success in combat.

Understand Chaos Zero Nightmare Gameplay

 

Here are the key gameplay mechanics every Chaos Zero Nightmare beginner should know:

  • In Chaos Zero Nightmare you can choose three combatants.

  • Each character uses cards that represent their skills or abilities.

  • You have a card deck from which you draw during battle.

  • On your turn, you draw and play cards to perform actions.

  • After your turn, the enemy takes their turn.

Cards System

The Card System is the main part of the game’s combat. Each card type has a unique role:

Cards System

 

  • Attack Cards (Red): Deal damage to single or multiple enemies.

  • Upgrade Cards (Green): Give buffs like increased strength or defense; removed after the battle.

  • Skill Cards (Blue): Help your team by healing, shielding, or drawing more cards.

  • Curse Cards: Negative effect cards from enemies or events, like bleeding effects. 

  • Status Cards (Gray): Neutral cards that might help a little buffs or minor debuffs.

Understand Key Features for Combat

There are several important systems in the Chaos Zero Nightmare Combat System that you need to understand to become more successful, especially in the Chaos Zero Nightmare early game. Here are the main key systems you should focus on:

Understand Key Features for Combat

 

Stress System

In Chaos Zero Nightmare, your characters don’t just take physical damage, they also experience stress during combat. Managing this system is crucial for keeping your team functional in long battles like chaos mode.

Stress System

 

  • The Stress Meter is located under the Team HP bar.

  • Each character has a purple Stress Bar that fills up during fights.

  • When it reaches 100%, the character suffers a breakdown, making their cards unusable.

  • Use healing or shield cards to reduce stress and keep your team steady through extended encounters.

Ego Point (EP) System

If the Stress System represents survival, the Ego Point System represents your team’s ultimate potential. Understanding how to build and spend EP can completely turn the tide of battle.

Ego Point (EP) System

 

  • The EP bar is visible in the bottom-left corner of the screen.

  • EP allows you to unleash ultimate skills for both combatants and partners.

  • You can use up to 6 Ego Skills in total, 3 from combatants and 3 from partners.

  • Earn EP by defeating enemies or using certain special cards.

  • Save your EP for critical moments to shift the outcome of difficult fights.

Sands of Time System

Every strategist makes mistakes, but in Chaos Zero Nightmare, you actually get the chance to undo them. The Sands of Time System lets you control time itself to correct your missteps. Represented by an hourglass icon, this system lets you rewind or retry specific actions.

Sands of Time System

 

You have three uses per battle to:

  1. Undo your last card

  2. Rewind to the start of a turn

  3. Reroll ultimate skills

Use these abilities wisely to fix costly mistakes or refine your strategy mid-fight.

Enemy’s Tenacity Gauge

Some enemies won’t fall easily, they have an extra layer of defense known as the Tenacity Gauge. Learning how to break it is key to dealing massive damage.

Enemy’s Tenacity Gauge

 

  • The Tenacity Gauge appears below the enemy’s HP bar.

  • It acts as a shield, reducing incoming damage.

  • Attack using weakness attributes or high AP cost cards to break the gauge.

  • Once the gauge hits zero, the enemy enters a Breakthrough State, becoming stunned.

  • This is your best opportunity to unleash powerful attacks and finish the fight.

Explore the Arc City

Arc City is the main hub in Chaos Zero Nightmare, filled with facilities that help you strengthen your team and manage your progress. It unlocks after completing Chapter 2 of the main story, making it an essential milestone for Chaos Zero Nightmare beginners. Here’s what you can do there:

Explore the Arc City

 

  • Visit the Coffee Shop: Stop by the Garden Café to grab quick energy boosts or store energy for later use.

  • Get Some Food Buffs: Dine at the Starshine Diner to gain temporary boosts like increased HP or attribute bonuses for upcoming battles.

  • Check Out Noo’s Shop: Spend Policy Points to buy Research Notes, Affinity items, and special keys for events or character upgrades.

  • Head to the Research Facility: Use Research Notes here to unlock new abilities and upgrade your progression trees for extra bonuses.

  • Go on Character Dates: Increase your characters’ Affinity Levels to unlock special rewards, story events, and bonus EXP.

  • Visit the Psychotherapy Center: Restore your combatants’ mental health, especially those affected by Mental Breakdown during battles. Regular sessions keep your team stable and ready for the next fight.

Upgrade and Level Up Combatants Early

The most basic, and most important, way to grow stronger is to level up your combatants. Each level boosts their core stats and unlocks new potential.

Upgrade and Level Up Combatants Early

 

  • Leveling up increases HP, Attack, and Defense, giving your team a solid foundation for tougher encounters.

  • Use EXP materials gained through exploration and daily missions to speed up progress.

  • Focus on your main three combatants first, pushing them to Level 40 as soon as possible for faster progression.

Once your team is leveled up, it’s time to enhance their Potentials. These work like promotions, unlocking stronger stats and traits for each character.

Upgrade and Level Up Combatants Early

 

  • Use special upgrade materials earned through farming or gameplay events.

  • Each Potential upgrade gives permanent stat boosts and sometimes unlocks new abilities.

  • Prioritize upgrading your core damage dealers or tanks first for the best early impact.

Equip Memory Fragments 

Think of Memory Fragments as your combatants’ equipment, they enhance stats, unlock bonuses, and drastically improve performance in battle.

  • Equip Blue and Gold Fragments whenever possible, as they offer the best stat boosts.

  • Completing fragment sets grants additional set bonuses that amplify your combat style.

  • Prioritize equipping your main combat team before experimenting with secondary units.

Tip: Keep an eye out for synergy, some fragment sets work better on support or damage-focused units.

Unlock Manifest Ego 

The Manifest Ego system lets your combatants reach their true potential, but it depends on luck and patience.

Unlock Manifest Ego 

 

  • You unlock stages using duplicate characters pulled from the gacha.

  • Extra copies automatically turn into Ego Boost materials for that specific character.

  • Each combatant has six stages, granting passive bonuses, stronger card effects, and stat boosts.

Tip: Since you can’t use other characters’ copies, rare units take longer to max out. Focus your summons on banners with your main damage dealers or supports, even a few Ego stages make a big difference.

Assign Partners for Synergies

In Chaos Zero Nightmare, every combatant can be paired with a partner, unlocking unique synergy effects that boost team performance. Each character belongs to a specific class, which defines their combat role and playstyle.

Ranger

More Game Modes: Farm More Resources

Farming resources is the best way for beginners to upgrade combatants and find more Memory Fragments to increase your power. Focus on the game modes that give the most resources. Here’s a breakdown:

More Game Modes: Farm More Resources

 

  • Missions: Missions are the main storyline gameplay. Focus on completing missions to increase your account level and unlock more features. Missions also give a large amount of rewards, making them essential for early progression.

  • Chaos: Chaos Manifestation is an exploration mode where you battle monsters using your combatants. Each battle focuses on specific attributes, so plan your team accordingly. From Chaos, you can earn legendary Memory Fragments and other valuable resources.
