1. Game Core Overview
This is a top-down action shooter that integrates deck building, real-time tactics, dynamic gunplay, and roguelike dungeon exploration. Players venture into endless randomized dungeons, build combat systems through real-time card drawing, deploy tactical units for coordinated battles, evade dense projectile barrages with flexible movement, and eliminate enemies with precise shooting. Supported by comprehensive progression systems including characters, weapons and equipment, players challenge layers of procedural levels and unlock exclusive achievements and card modifiers, bringing a brand-new adventure experience to every dungeon run.
2. Worldview & Story Background
Following the collapse of ancient planar realms, the endless Abyss Dungeon descended upon the world. Remolded randomly by extradimensional magic, this dungeon is infested with countless demonic creatures. The warrior clans that once guarded the continent fell apart. Surviving warriors delved deep into the dungeon to uncover the truth behind the planar catastrophe. Players take on the role of a rookie warrior who ventures into the abyss to search for missing mentors and investigate the source of the dungeon’s anomalies.
Each layer of the dungeon is reshaped by chaotic magic. The deeper players descend, the stronger the monsters become and the rarer the secret treasures hidden within. Throughout their exploration, players will gradually uncover the hidden truth behind the dungeon’s creation and the interdimensional invasion. Special hidden chambers preserve rare equipment and secret cards left by veteran warriors of the past, making every in-depth exploration a life-or-death gamble.
3. Four Core Gameplay Mechanics
1. Deck Building (Core of the Card System)
At the start of each dungeon battle, players draw hands from a global randomized card pool, which expands continuously with exploration progress and collected modifiers. Cards are divided into four categories: Summon Cards, Shooting Buff Cards, Tactical Buff Cards, and Field Trap Cards. Free from fixed deck restrictions, players can draw and assemble combat hands dynamically on the battlefield.
Clearing rooms unlocks new card modifiers that optimize card effects, such as increasing summoned units’ HP, shortening weapon reload time, and boosting area-of-effect damage. Duplicate cards can be refined to permanently enhance the base attributes of the corresponding cards.
2. Tactical Summoning
Players deploy combat troops via summon cards. Melee tank units block chokepoints and withstand monster charges, while ranged units provide terrain-based fire support to form a coordinated offensive and defensive frontline. Each summoned unit possesses unique passive abilities. Rare premium summon cards can spawn elite combat units, which can trigger powerful combo bursts when matched with shooting cards. Reasonable deployment positioning is the key to breaking through dense monster hordes.
3. Dynamic Gunplay
Players control their character with full free movement from a top-down perspective. The dungeon is filled with enemy projectile barrages, ground traps and explosive formations. Players must evade intensive incoming attacks through agile positioning. It is essential to constantly adjust stances to find blind spots and optimal output positions, and take cover behind walls and obstacles to deal damage. When melee enemies approach, players can switch weapons or summon units for containment, balancing movement tolerance and combat efficiency.
4. Dungeon Exploration (Foundation of the Level System)
The game adopts a roguelike procedural generation system. Room layouts, enemy distributions, item shops and secret event chambers are fully randomized in every exploration run. Levels are designed in progressive layers, extending from shallow outer dungeons to the core of the abyss. Each layer consists of multiple randomized rooms and a final boss chamber. Defeating the layer boss unlocks access to the next dungeon area.
Rooms are classified into five types: Combat Rooms, Event Rooms, Equipment Shops, Card Forges, and Rest Chambers. Random events grant positive buffs or negative debuffs, greatly enriching the randomness and replayability of exploration.
