Earth vs Aliens is an idle strategy game where you lead Earth’s last defense against a growing alien threat. Build and upgrade farms, barracks, and factories across a grid-based command board, grow your economy, train your army, and decide when to strike back.

The galaxy keeps moving while you manage Earth. Alien factions earn resources, raise armies, fight each other, and create battle news as the war develops automatically. Your job is to keep Earth alive long enough to outproduce, outlast, and defeat the invasion.

Designed for quick sessions and steady progression, Earth vs Aliens mixes incremental growth with light strategy. Watch your income, choose the right upgrades, expand your military power, and launch manual attacks when the timing is right. Every building choice helps Earth survive a little longer in a galaxy that is always getting more dangerous.
