## What is Polygon Defense?

Hold the line in POLYGON DEFENSE — a fast, stylish blend of tower defense, survivor action, and roguelite upgrades, wrapped in a sleek neon-polygon aesthetic.

Waves of geometric enemies pour toward your defense line. Your Guardian fires automatically — your job is to think fast, choose the right upgrades, and build a defense that can survive whatever comes next. Every run is different. Every choice matters.

▶ EASY TO PLAY, HARD TO MASTER
Jump straight into the action with intuitive one-handed controls. Anyone can pick it up, but only the smartest tacticians can push through the toughest stages and bosses by drafting the perfect synergy. Play anytime, anywhere.

▶ FIVE ELEMENTAL TURRETS
Deploy and command a unique squad of geometric turrets, each featuring its own devastating playstyle:
• Circle — Blazing fire AoE
• Triangle — Piercing energy lasers
• Rectangle — Freezing ice control
• Polygon — Heavy physical impact
• Star — Chaining electric strikes
Mix, match, and position your grid to counter relentless enemy variants.

▶ ROGUELITE UPGRADE CARDS
Level up mid-battle and draft from a dynamic pool of upgrade cards. 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. Aim higher than a simple victory — finish with high HP or pull off a flawless run to unlock top-tier rewards.

▶ 30-DAY DAILY LOGIN REWARDS
Keep your armory stocked! Check in every day for free coins, cores, and modules. Reach 7-, 14-, and 21-day milestones for massive bonuses, and claim a huge Grand Reward on Day 30. The streak resets so the rewards never stop flowing.

▶ SLEEK, MINIMALIST DESIGN
Experience a crisp neon-polygon look with satisfying particle effects and punchy, responsive audio. The clean visual design ensures the action remains perfectly readable, even when the screen is flooded with hundreds of enemies.

▶ PLAY YOUR WAY
• Free to Play — Premium experience with optional rewarded ads only when you want a boost.
• Pure Single-Player — Perfect for quick, intense gaming sessions.
• Cloud Save — Keep your progress completely safe across device reinstalls.
• Global Localization — Fully available in English, Korean, Japanese, and Chinese.

Can you upgrade, evolve, and outsmart the geometric horde?
