Arcalis: Tower Defense
iO Digital Studio
Arcalis is a single-tower endless wave defense game. Equip your archer, power up your tower and hold back the never-ending raids of the Forest Raider Tribes!
⚔️ HOW IT PLAYS
Your archer fires automatically — you focus on strategy. Spend the gold dropped by enemies on 12 different in-run upgrades: damage, attack speed, crit, multishot, ricochet, tower HP and more. The longer you survive, the bigger the rewards!
🏹 GEAR UP YOUR HERO
6 equipment slots, 14 unique items, 4 rarity tiers. Every item has its own signature ability: poison arrows, piercing shots, gold rush... Merge 3 identical items to evolve them into a higher rarity!
🌟 PERMANENT POWER SYSTEMS
• Talent Tree: earn permanent points as your hero levels up
• Resonance: Crystal Dust multipliers that carry over between runs
• Chests: unlock new items from Wooden and Crystal chests
👹 THE FOREST RAIDER TRIBES
10 different creatures: gold-stealing thieves, burrowing moles, healing shamans, explosive bombers... And every 10th wave one of 5 boss families is waiting for you!
🏆 CHASE THE RECORD
Break your highest wave record and climb the global leaderboard. Every new record earns you gems!
📬 LIVE FEATURES
Daily gifts, quests, an in-game mailbox and gift codes — something new every day.
