Earth’s Last Defense Idle Fleet

Earth's Last Defense is an idle fleet-command defense game about holding the line against an alien hive invasion.
Start with Earth, your hero ship, a fighter, and a mining ship. As the battle runs in real time, your fleet earns resources, destroys enemies, unlocks new ships, and grows into a full defensive armada. Every wave pushes harder, every upgrade matters, and every run helps build a stronger command force.
Build and upgrade your fleet:
- Fighters, mining ships, repair drones, corvettes, and heavier warships
- Hero ships with progression and combat upgrades
- Turrets, modules, skill trees, and permanent research
- Resource systems built for long-term idle progression
The game is designed around passive progression, but your choices still matter. Pick upgrades, expand your shipyard, manage your fleet limits, improve Earth's defenses, and prepare for stronger enemy waves.
When the hive gets too strong, rebuild smarter. Earn power over time, unlock deeper systems, and push farther into the invasion.
Earth is not saved in one run. It is defended one wave at a time.
