Our take on Alien Worms Invasion

Rather than keeping tower defense to base protection, the game combines it with exploration, recruitment, and attacks on worm nests. Progress depends on managing defensive positions and offensive forces while the enemies grow stronger.

What is Alien Worms Invasion?

Alien Worms Invasion combines futuristic exploration with tower defense.

Players explore unknown areas, build bases, and produce units to defend against attacking worms and strike their nests. Rescued people can become civilians, while civilians can be armed as soldiers. Available units include soldiers, cannons, engineering airplanes, and mecha commanders. During battles, engineering airplanes transform energy from trees in worm forests for building upgrades. Soldiers attack nearby worms and those near the base to obtain energy. Cannons deal heavy damage, while mecha commanders defend the base and lead armies against the worms. Enemies become stronger as play continues, so completing tasks requires balancing defensive and offensive forces.
