Alien Defense: World Under Attack
About Alien Defense: World Under Attack
Alien Defense: World Under Attack drops you into a mech cockpit as alien paratroopers descend on real cities reconstructed from actual map data. The seven battlegrounds — Moscow, New York, London, Paris, Washington, San Francisco, and Beijing — each have their own campaign missions, and every city has a landmark protected by an energy shield that you must keep standing. A jetpack-equipped combat mech gives you the vertical range to intercept invaders before they reach the streets, and a toggle between third-person and first-person view lets you shift perspective on the fly.
How to Play Alien Defense: World Under Attack: Defend the Shield
The core objective is to protect the energy shield and its generators from incoming alien waves. Shoot the invaders while they are still parachuting down — any alien that lands will begin attacking the city directly. Campaign missions run across all seven cities, and an endless Siege mode extends the challenge beyond the story content. Weapons can be upgraded, and mech skins are available to customize your unit.
