About

Idle Planet Defender

Read full description

GET READY. EARTH NEEDS YOU. An alien invasion has reached Earth. Fortunately, humanity has prepared the only reasonable response: An unreasonable amount of firepower. Welcome to Idle Planet Defender โ€” an idle strategy and space defense game where you defend Earth, destroy alien fleets, upgrade powerful weapons, unlock powerful research upgrades and features, and fight many different alien forces across the galaxy. The aliens brought a fleet. We brought weapons. BUILD THE PLANETARY DEFENSE GRID Turn Earth into the most heavily armed planet in the galaxy. Deploy and upgrade Tesla weapons, heavy cannons, scatter guns, orbital weapons, satellites, combat drones, cryogenic technology, chain lightning and several weapons that probably should not have passed safety testing. Then activate your Ultimate Weapons. Stop time. Open a black hole. Turn enemy airspace into a regrettable life decision. RESEARCH. UPGRADE. OVERKILL. Unlock 90+ research nodes and continuously improve your defense grid with powerful upgrades, systems and enhancements. Increase your firepower. Strengthen your economy. Unlock new technology. Build better weapons. Everything you unlock stays with you. Human progress is permanent. The aliens, less so. 50 ENEMY SHIPS. 50 MASSIVE BOSSES. Fight 50 different alien ship classes with unique threats, defenses and increasingly questionable amounts of armor. Crack their shields. Destroy their armor. Watch massive warships fall apart above the planet they made the administrative mistake of invading. They have numbers. You have boom. Do the math. DEFEND MORE THAN EARTH Earth is only the beginning. Expand your planetary defense operation across new worlds including Mars, Inferno, frozen planets, storm-covered worlds and other locations humanity discovered and immediately decided needed guns. Claim them. Upgrade them. Defend them. THE DEFENSE GRID NEVER STOPS Your automated weapons attack incoming enemies while you focus on strategy, research and upgrades. Optimize your build. Grow stronger. Destroy bigger fleets. Then prepare for the next invasion. CLIMB THE RANKINGS Complete daily missions, collect supply drops, spin the Stellar Wheel, earn rewards, progress through the Milestone Pass and climb the global rankings. Somewhere in the galaxy, another commander thinks their defense grid is better than yours. Prove them wrong.
