Crystant is a top-down post-apocalyptic survival strategy game.

You awaken as a “test subject” inside a mysterious facility buried deep underground.

You will explore the unknown depths of the earth, using resources and strategy to overcome various mutated creatures.

Each expedition is a completely new challenge.

Random events, deadly traps, unknown areas, and risk-reward route choices all combine to create a highly variable survival journey.

As you progress, you will gradually unlock new abilities and information, piecing together the truth behind the apocalypse.

And in this world on the brink of collapse—

what will the ending be?

Will you manage to escape, or be swallowed by the darkness?

Introduction

You wake up from a sudden quake, reminded of your current predicament—locked away in a windowless laboratory.
Suddenly, the door opens. Blinding white light floods in, revealing a long corridor leading into the unknown. Flickering lights shimmer in the distance.

After a long hesitation, you finally muster the courage to venture forward…

Key Features

Encounters filled with unknown dangers

Equip specialized weapons to enhance your class abilities
Different classes can equip their corresponding signature weapons, allowing each character to unleash their full potential.

Scavenge for resources and struggle to survive
Resources are scarce and filled with danger. Every expedition may lead to a breakthrough—or a disaster. You must make critical decisions with limited supplies to ensure you survive long enough to reach the next floor.

Unique tactical, turn-based combat system
Combat is built on a predictable yet deeply strategic grid-based system. Players must carefully consider positioning, skill timing, and enemy behavior patterns.

Enemies with randomized attribute enhancements
During every run, enemies may gain random enhancement traits, turning familiar foes into unpredictable threats and forcing you to adapt your strategy.

Stronger Enemies
In the deeper areas, you’ll encounter more powerful foes — enemies with higher defenses, deadlier attack patterns, and unique abilities. Stay cautious and use your resources and strategies wisely if you hope to survive.
Forge Your Own Combat Build
Master the four core attributes, enhance your team’s capabilities, and build the strategy that suits you best.
Collect special chips to accelerate progression
Learning Chips can be used to enhance core attributes and accelerate your character’s growth.
Access recovery, training, and insight functions in specific areas
In designated rest areas, you can use Recovery to regain HP through short rest, Training to consume Chips for ability upgrades and faster EXP gain, and Insight to operate surveillance systems that remotely reveal sections of the map. These features provide breathing room between encounters and allow you to plan ahead for the increasingly dangerous zones ahead.
Out-of-run upgrades unlock new classes and enhance abilities
By earning special points during gameplay, players can unlock additional character classes and passive upgrades, encouraging them to continuously experiment with different playstyles.
Carry over EXP and CV into a new run
After each cycle, accumulated experience and special currency are carried over, giving you an advantage in the next run and reinforcing the long-term progression of a roguelite structure.
Collect story fragments to uncover the truth behind the disaster
Scattered research logs and fragmented documents can be found throughout the facility. Piecing them together gradually reveals the laboratory’s secrets and the true cause of the disaster.
