Neon Shape War: Idle Synthwave

The arena is alive with shapes — and they want your core.

Neon Shape War: Idle Synthwave is a fast, stylish geometric defense game where your turret auto-fires while you focus on upgrades, economy, and survival. Hold the center. Stack your build. Climb the global ranks or push forever in Endless mode.

◈ RANKED OR ENDLESS
• Ranked — 30-minute countdown run; submit your best score to the global top 100
• Endless — no time cap; survive as long as your build can hold

◈ DEFEND THE CORE
Geometric enemies spawn from every edge and march inward. Keep your pink core alive, manage HP, and outlast wave after wave of triangles, squares, pentagons, and hexagons. Face fast Strikers, ranged Shooting Stars, and massive decagon bosses every 10 waves.

◎ IDLE COMBAT, ACTIVE DECISIONS
No manual aiming required. Your turret targets the closest foe inside the attack ring. You choose when to invest in damage, when to shore up defenses, and when to unleash powerups at the perfect moment. Unlock AUTO powerups at wave 100 to fire abilities on cooldown.

⚡ SIX BATTLE POWERUPS
• Shockwave — blast and push nearby enemies
• Bombard — strike every foe on screen
• Shield — block all contact damage
• Overcharge — double your fire rate
• Freeze — stop enemy movement cold
• Heal — restore 35% of your max HP

♥ DEEP UPGRADES
Seventeen upgrade paths across five branches:
• Health — Max HP, Regen, Armor
• Damage — Power, Fire Rate, Crit, Range
• Money — Income, Bounty, Interest
• Tech — Pierce, Scatter, Crit Mastery, Execute
• Sync — Life Steal, Haste, Salvage

Spend early, snowball hard, and craft a build that survives deep into the run.

◈ GLOBAL LEADERBOARD
