Anyone can pick it up, but only the smartest tacticians can push through the toughest stages and bosses by drafting the perfect synergy.

Choose from general stat boosts, chain cards, advanced combos, and powerful special evolutions. Chain the right cards together to create broken, screen-clearing builds. No two runs ever play out the same. ▶ GROW STRONGER EVERY RUN Collect coins, cores, and turret modules to invest in permanent meta-progression: • Cores: Permanently boost your Guardian's core stats (Helmet, Armor, Weapon, Shield, Boots) • Turret Modules: Upgrade each turret's base power and efficiency Come back stronger and crush the stages that once felt impossible. ▶ STAGES, BOSSES & CHALLENGES Battle through escalating zones packed with unique grid layouts and tense boss fights.
