The mothership has landed and the aliens are marching on your base. Build a squad of stickman defenders along the road and stop every wave.

• 12 stickman towers: Archer, Dart Shooter, Boomerang, Gun Shooter, Landmine Placer, Knife Thrower, Healer, Pyromaniac, the Belt Stickman (50 damage belt whip) and the Catapult Guy, who throws spiky balls for 125 damage, plus the Ninja Stickman and Laser Stickman sold by Sergeant Alex
• Earn money for every alien you stop and for clearing waves, then spend it on new towers and upgrades
• 6 alien types: the Basic One, the Major, the Tanky Boi, the Bomb Monster who throws bombs that stun your stickmen, the Big Brother every 5 waves, and the Shadow Clone Jutsu every 10 waves with a whopping 5000 health that spawns 10 aliens every 10 seconds
• Upgrade shop: earn coins from every alien and wave, and gems every 3 waves and from big bosses. Spend them on 18 permanent upgrades like Sharp Weapons, Coin Magnet, Boss Buster, Critical Hits and Field Medic
• Sergeant Alex unlocks at round 20 in the Grasslands: buy new stickmen and 3 extra upgrades (Drill Training, Sergeant's Pay, Supply Drops)
• Daily rewards: play every day for a 7-day streak of coins and gems
• Skip rounds with coins or gems between waves (except the world boss round)
• Levels (L on the title): every world you reach stays unlocked forever, even after a New Game or game over deletes your save, so you can replay it any time. Skip ahead to locked worlds with coins or gems
• Treasure chests parachute out of the sky during rounds: click them for money, coins or gems
• Shadow Clone Ninja aliens split into two clones when hurt
• The Arena (R on the title): fight a real player online - every 4 aliens you stop sends one to them; last base standing wins
• Every world has its own 50,500 health Mischief boss at wave 20 riding a big machine that zaps your stickmen. Defeat it to move to the next map, with towers fully refunded. 5 maps in total: Grasslands, Ancient Egypt, Pirate Seas, Wild West and Frostbite Caves, each with its own themed aliens
• Secret codes: aliens sometimes drop code scrolls and every world boss like Dr. Alien Mischief always drops one. Redeem them in Shop > Codes
• Progress saves automatically between waves: your map, wave, money, lives and towers are restored when you press Continue
