Cosmic Summon

Cosmic Summon is a unique blend of gacha summoning and tower defense strategy. Summon powerful heroes, place them on the battlefield, and defend your wall against endless waves of enemies — all under the stars of real constellations.

SUMMON & COLLECT 12 UNIQUE HEROES
Each hero brings a distinct combat style to the battlefield:
• Wind Piercer — Piercing shots that penetrate multiple enemies
• Blaze Caster — Fire splash dealing area damage
• Frost Weaver — Slows enemies with freezing attacks
• Thunder Chain — Chain lightning bouncing between targets
• Cannon Lord — Devastating splash damage in a wide radius
• Wind Dancer — Summons tornadoes that damage and slow
• Venom Curse — Poisons enemies with damage over time
• Shock Guard — Shockwave knockback to push enemies back
• Armor Breaker — Curse attacks that shred enemy armor
Plus 3 support heroes: Wall Keeper (heals your wall), Gold Digger (generates gold), and Melodist (buffs team attack speed).

MERGE TO EVOLVE
Combine two heroes of the same type to upgrade them. Progress through 7 rarity tiers — from Spark to the legendary Genesis rank. Higher rarities unlock stronger abilities and stunning visual effects. Strategic merging is the key to surviving later waves.

FACE 28 ENEMY TYPES + BOSSES
Every few waves, new enemy types appear with unique abilities:
• Stealth lurkers that vanish from sight
• Splitters that divide into smaller enemies on death
• Healers that restore nearby allies
• Chargers that rush your wall at extreme speed
• Reflectors that bounce damage back
• Summoners that spawn endless minions
• And many more — each demanding a different strategy.
Boss encounters every 5 waves test your entire defense.

50 CONSTELLATION-THEMED WAVES
Battle under the stars of real constellations — from Aries to Orion, Cassiopeia to the Southern Cross. Each wave features a beautifully rendered constellation as your battlefield backdrop.
