Aliens vs Zombies: Invasion for Android

Quick summary

Aliens vs Zombies: Invasion is a free Android title that mixes tower-defense strategy with fast-paced action. You pilot a flying saucer across destructible stages, absorbing objects to collect resources and earn experience. Those resources fund the construction and improvement of defensive turrets to hold off swarming zombies.

How the game plays

You steer the UFO through each level, targeting items and structures to gather materials and XP. Collected resources are spent on building and upgrading guns and other defenses around your base. Combat alternates between active piloting and base management, requiring both reflexes and forward planning to survive successive zombie waves.

Challenges and level design

Levels are designed around chaotic set-pieces and environmental destruction, forcing you to adapt quickly as situations change. Waves of undead come repeatedly with increasing intensity, so timing upgrades and positioning your firepower strategically is essential.
