Protect the picnic. Learn from defeat. Come back stronger.

Backyard Defenders is a single-player tower defense game where hungry insects turn an afternoon picnic into a fight for survival. Build your defenses across a 15-by-7 battlefield, spend earned sugar on upgrades, and decide which threats to stop first.

Six ways to defend your backyard

• Salt Shaker: Damage groups of nearby bugs.
  
• Bug Zapper: Chain lightning between enemies.
  
• Water Sprinkler: Push enemies back with water attacks.
  
• Spider Web: Slow passing enemies and improve its effect with upgrades.
  
• Fly Swatter: Strike nearby enemies with heavy melee attacks.
  
• Water Balloon: Hit groups with splash damage and slowing effects.

Every run funds the next

Waves grow stronger, and surviving your first boss takes preparation. Earn a separate research fund as you play, then spend it on permanent upgrades to your economy and defenders. Defeat ends the run, but your research carries forward. Experiment with new layouts and return with a stronger starting position.

Face five boss types

Take on the Ant Empress, Beetle Titan, Spider Weaver, Moth Oracle and Locust Storm. Each brings its own abilities. A boss that reaches the picnic ends your run.

Earn your progress through play

All sugar is earned in the game. There are no in-game purchases. Unlock six Steam achievements and use Steam Cloud to carry your account's saved progress between Windows PCs. Runs save at wave checkpoints; exiting during a wave resumes from its starting checkpoint.
