About this game
Warrior's Memory: The Hollow Strata
Warrior's Memory: The Hollow Strata is a card game where you build your deck before each challenge, then collect, fuse, and upgrade cards as you battle your way through the Strata.
With over 1,000 cards, flexible pre-run deckbuilding, and fusion-based upgrades, create your own combos and take on powerful enemies.
Key Features
Over 1,000 Cards
Discover a wide variety of cards, with more planned for future updates.
Strategic Pre-Run Deckbuilding
By fighting repeatedly and leveling up your character, you can expand your deckbuilding options. Add stronger cards and more powerful combos to your deck before each challenge.
Grow Stronger Through Card Fusion
Fuse cards of the same level to create a stronger card one tier higher.
Collect Cards and Items
Use in-game currency to buy and collect cards and items. Items can also be added to your deck before a challenge, opening up even more strategic possibilities.
A Unique Daifugō-Style Mini-Game
Includes a special mini-game inspired by Daifugō, also known as President.
Combat
Deploy your units against the enemy’s formation and fight back with your own.
Withstand enemy attacks, deal damage, and reduce the enemy’s HP to zero to win.
The BT System
This game features a unique combat system where the enemy’s BT becomes your combat power, while your BT becomes the enemy’s combat power.
Rather than focusing only on your own strength, success depends on choosing the right units for each opponent.
Skills and Assist Cards
Many cards can be deployed as units, but they can also be used as Assist Cards to turn the tide of battle.
Cards also have a wide range of skills. By using them effectively, even weaker units can defeat stronger enemies.
Library
In the Library, you can view detailed information on the cards you have collected.
Browsing your collection and planning new decks and combos is part of the experience.
About Early Access
This game is currently in development.
We plan to continue updating it with new cards, modes, and system expansions.
Planned Updates
A new mini board game inspired by Mahjong-like matching games, using in-game cards
Continued expansion with a goal of exceeding 4,000 total cards
New special Strata that expand the main ADVENTURE mode
Additional new game modes that differ from the existing modes
About the Use of AI
AI has been used in parts of the programming process, as well as in many card and UI design elements.
Depending on future development conditions, we plan to gradually replace key card illustrations with redrawn versions by illustrators.
