About Alien Invasion
Alien Invasion is an Android game in the survival/idle-RPG space. You take on the role of a venom-infused alien being whose mission is to dominate by evolving, defeating human adversaries and powerful bosses. The gameplay combines idle mechanics—you build up strength even when you’re not playing—with active battles and strategic upgrades. As you progress, you upgrade your alien’s speed, attack radius, capacity, and other traits to devour waves of enemies and scale up your dominance. Because it’s in the idle category, you’ll find plenty of opportunities to make progress in short play-sessions or casually. On FilesCEO you’d highlight that the APK is free to try, mention that the game contains ads and in-app purchases (common in this genre), and note device-compatibility (modern Android versions recommended).
