About this game

You answered a distress signal. It was a trap. Your ship came down hard on a hostile planet. The wreck still has power, the turrets still turn, and something out there heard the crash.

Space Defense: Alien Base TD is a sci-fi tower defense game. Build turrets around your crashed ship, grow the wreck into a fortified base and hold off 100 waves of alien creatures, war machines and warships until you can launch for home.

FROM WRECK TO CITADEL
• Grow your base through five stages: Wreck, Camp, Outpost, Base and Citadel
• Up to 12 turret slots on the hull, the watchtower and defense platforms
• Raise a ring barrier, from scrap barricades to a glowing energy shield
• Your Power Plant keeps making energy while you are away

8 TURRETS. YOUR STRATEGY.
• Pulse Cannon, Flak Cannon, Rotary Laser, Railgun, Fusion Torch, Ion Cannon, Swarm Missiles and Particle Lance
• Turrets fire on their own. Tap an enemy to focus every turret in range on it
• Upgrade each turret type to level 8 and watch it change: new barrels, armor, power cells and a gold mastery finish

FACE THE INVASION
• 26 enemies: crawling larvae, leaping hunters, armored beetles, dive-bombing flyers, scanner drones and a Sand Leviathan that rises from below
• Five boss warships, one at the end of each chapter, firing missile salvos and launching drop pods
• In the final wave the Invasion Mothership calls down a Titan from orbit

POWERS AND EVENTS
• 7 special powers: Freeze Bomb, EMP, Signal Decoy, Support Ship, Sun Flare, Shutters Down and a Survivors missile run
• Sonic Blast clears the field when the swarm gets too close
• Waves come at noon, at sunset and at night. Sandstorms, power outages and a Red Sun change the rules

100 WAVES. ONE WAY HOME.
• A 100-wave campaign in 5 chapters, then Endless Defense
• Earn up to 3 stars per wave and replay any wave in Star Hunt
• Wave of the Day: one shared challenge, the same for every player
• Three planets to defend: Forest, Desert and Ice. Looks only, never power

PLAY ANYWHERE
• Space tower defense you can play offline, no internet needed
• Simple portrait controls, made for one hand

The game is supported by ads. Optional in-app purchases include removing interstitial ads, a starter pack and the Ice planet look.
