HOW TO PLAY
★ WELCOME TO STAR DEFENDERS ★
Star Defenders is a tower defense game where you defend your mothership against waves of alien invaders emerging from a black hole. Build defense platforms, upgrade them with powerful abilities, and survive the onslaught!
GETTING STARTED
Place 4 platforms to begin the first wave. Enemies travel from the Black Hole (top-left) to your Mothership (bottom-right). Position towers along the path to maximize damage. Don't block the path completely!
THE MISSION
Survive 101 waves of alien invaders. A mighty boss appears every 10 waves — defeat them to earn massive XP. On Wave 101, THE LEVIATHAN arrives: an unkillable grand finale. Deal as much damage as possible before it reaches your mothership. Your final score is the total damage dealt!
LIVES & LEVELING
You have 5 hearts — each enemy that reaches your mothership costs one. Kill enemies to earn XP and level up. Each level grants an upgrade module: drag it onto a tower to specialize it. Between waves you also earn new platforms to expand your maze.
PERKS
Complete achievements to unlock permanent perks — like extra starting platforms, bonus damage, or extended range. Activate up to 3 perks from the PERKS menu before starting a run!

TOWER SYSTEM
All towers start as basic platforms that shoot at enemies. Level up by killing enemies to earn upgrade modules. Drag modules onto towers to specialize them. Each tower can have up to 4 unique upgrade types, and each type can stack up to 5 times for increased effect!
⚡ ATTACK SPEED (Cyan)
+50% attack speed per stack. Stack 5x for +250% — a bullet hose. Great for every build!
💥 DAMAGE (Red)
+1 damage to every shot per stack. Multiplies with crits, chains, and splash — the backbone of any high-DPS tower.
⏱ SLOW (Purple)
Slows hit enemies by 58% (up to 85% at 5 stacks) for 3-5.5 seconds. Elite crowd control — give your other towers time to work.
❄ FREEZE (Ice Blue)
Periodically freezes the target solid for 0.8-2 seconds. Higher stacks freeze longer and more often. Bosses resist but aren't immune!
☠ WEAKEN (Orange)
Marked enemies take +15% damage per stack (up to +75%) from ALL towers for 3.75-6.75s. Devastating on bosses — a must for late game.
⚡ CHAIN LIGHTNING (Yellow)
Projectiles chain to +1 additional target per stack with 25% damage falloff per bounce. Chains carry your other effects too. Stack 5x to hit 6 enemies!
💣 SPLASH (Orange)
Shots explode for area damage with +60% radius per stack. Excellent against tight clusters and Splitter swarms.
🎯 SNIPER (Cyan)
+40% range per stack. Stack 5x for +200% range and snipe enemies from across the map with long-range tracer rounds.
☠ POISON (Green)
Applies a damage-over-time toxin: 4.5 damage/sec for ~5s at 1 stack, scaling to 9 damage/sec for ~8s at 5 stacks. Melts tanky enemies.
➜ SHRED (Silver)
Projectiles pierce through +1 enemy per stack, and every hit permanently shreds 3-7% of the target's max HP. Shred never wears off!
✦ SPLITTER (Pink)
Tower fires +1 additional projectile per stack in a spread pattern at 75% damage, targeting different enemies when possible. Stack 5x for 6 simultaneous shots!
✧ PRECISION (White)
+8% crit chance and +15% crit damage per stack. Crits start at 2.5x damage — fully stacked you'll crit nearly half the time for 3.25x!
ENEMY TYPES
Each enemy type has unique stats and abilities. Learn their patterns to build effective defenses!
BOSS GAUNTLET
A boss arrives every 10 waves. Platform placement locks during boss fights, so build your maze beforehand! Defeating bosses earns huge XP — and killing the later bosses unlocks powerful perks.
WAVE 10 — SENTINEL
Your first real test. Tough, steady, and unbothered by your starter maze.
WAVE 20 — VANGUARD
Winds up and charges forward at high speed. Long slow-heavy corridors blunt its momentum.
WAVE 30 — WARDEN
Cycles a 50% damage shield, and on death splits into 6 SENTRY minions. Keep damage ready for the split!
WAVE 40 — GUARDIAN
Raises a shield every few seconds that halves incoming damage. Time your burst for the gaps.
WAVE 50 — YIN & YANG
Twin bosses that share damage. When one falls, the survivor enrages with surging speed and power.
WAVE 60 — INFERNO
Continuously spawns waves of fast fireball minions. Splash and chain towers shine here.
WAVE 70 — HYDRA
On death, splits into SHARD mini-bosses. The fight isn't over until every shard is destroyed.
WAVE 80 — PRISM
Cycles rainbow shields: poison immunity, damage reduction, slow immunity, and an aura that slows nearby towers. Adapt on the fly!
WAVE 90 — GLACIER
Emits a frost aura that slows the attack speed of nearby towers by 50%. Long-range snipers stay safely outside it.
WAVE 100 — OVERLORD
A massive tyrant that endlessly spawns enemies while it marches. Kill it and every remaining enemy dies with it.
WAVE 101 — THE LEVIATHAN
The unkillable grand finale. It cannot be stopped — only slowed. Deal maximum damage before it reaches the mothership. Your total damage is your legacy on the leaderboard!
NEBULA SYSTEM
Colorful pixel-art nebula clouds drift across the battlefield. Position your towers inside nebulas to gain powerful stat bonuses! Nebulas move slowly, so plan your tower placement carefully.
⚪ PRECISION NEBULA (White)
+50% Critical Hit Chance — Towers inside this nebula deal devastating critical strikes much more often! Combine with Precision upgrades for guaranteed crits.
🔵 VELOCITY NEBULA (Cyan)
+100% Attack Speed — Towers inside fire TWICE as fast! Stack with Attack Speed upgrades for incredible DPS.
🔴 POWER NEBULA (Red)
+5 Bonus Damage — Every shot from towers inside deals 5 extra flat damage. Great for fast-firing towers!
ASTEROIDS
Space rocks of various sizes float through the battlefield — small, medium, large, and rare Mega Asteroids. They're purely visual and don't affect gameplay, but they add to the cosmic atmosphere!
PATH PREVIEW
Hover your mouse over the Black Hole or Mothership to see the glowing path enemies will take. Use this to plan your tower placement!
