Mutation Surge

Humanity has established a frontline base on a planet rich in rare energy resources for research and extraction. However, a mysterious alien force suddenly emerged from deep within the planet, severing communications and causing the outer facilities to fall one after another. You take on the role of a combat robot from an expedition unit, launching from the base’s only safe zone— the Control Room—and venturing into the mutated sectors. Battle through one occupied room after another, confronting invaders, gathering resources, and assisting scientists in rebooting critical systems, while gradually uncovering the hidden secrets of this planet. Through repeated deployments and extractions, you’ll advance the story, unlock new equipment and skill modules, and grow stronger to face even greater challenges ahead. Combat That Rewards Timing: Fast Reload Mechanic Every reload presents a chance to trigger a “Perfect Reload”, empowering your next attack or skill. Mastering timing and rhythm is key to dominating the battlefield. Customizable Equipment and Skill Loadouts Before each mission, freely configure your loadout: primary weapon, secondary weapon, ammo type, active skill, and support items—crafting a unique combat style and strategic approach. Roguelite Progression with Continuous Room Challenges Each run is composed of randomly generated combat rooms. Clear them to choose your next route and advance step by step toward the boss battle. Resource Exploration and Progressive Unlocks During each run, you can acquire enhancement items and rare loot. If you successfully extract, these resources can be brought back to base to unlock new skill modules, weapons, and character upgrades, deepening both story and gameplay progression. High-Risk, High-Reward Extraction Experience Dying during a mission causes you to lose most of your rewards—but special rooms and systems allow early extraction or partial resource delivery. Every choice between pressing deeper or retreating safely will shape your growth and long-term strategy.
