After climate collapse and extreme pollution brought civilization to ruin, only mutated monsters and ruthless crime factions remain in the cities. As a commander who survived the chaos, your mission is to rebuild your territory and defend four independent battlefronts from relentless assaults. Each frontline functions as its own lane—if one falls, you’ll need strategic choices to reclaim it and restore your strength.

Battles revolve around recruiting and deploying allies. Every ally features unique attack patterns and skills, and can be combined to evolve into higher tiers. Because available allies and combinations change each run, even the same stage demands new strategies and adaptation.

Enemy waves vary widely—from human factions and criminal syndicates to mutated beasts—each with distinct behaviors and difficulty levels. While safe zones feature more predictable enemies, lawless and ruined areas punish every mistake: losing a lane directly weakens your defenses, forcing constant tactical decision-making. Each stage reflects its region’s characteristics and enhances immersion, with survival at the core of every fight.

Outside of combat, you can develop city structures such as your headquarters, research labs, banks, and entertainment facilities, enabling long-term progression. Randomization, unit combinations, and growth systems intertwine to create fast-paced battles and strong replayability.
