Aliens vs Zombies: Invasion is a strategy-action tower defense mobile game where players take control of an alien flying saucer tasked with surviving a zombie apocalypse. The core gameplay revolves around devouring objects, collecting resources, leveling up, and building powerful defense cannons.

As zombies attack relentlessly, players must balance resource gathering, base defense, and upgrade management. Each object consumed by your saucer grants XP, allowing you to improve abilities and unlock stronger defensive systems.

The game combines real-time strategy, action mechanics, and progression systems, making every level more challenging and rewarding. Strategic planning is essential to survive increasingly aggressive zombie waves.
