About Alien Worms Invasion
Alien Worms Invasion is a futuristic exploration and tower defense game set after alien worms defeat humanity on Earth. Survivors flee into space aboard a spaceship, where the player character—a former captain—gradually takes revenge on the worms with his crew. You explore unknown areas, build bases and units, and balance defense against attacks on the worms’ nests. Enemies grow stronger the longer you play, and completing tasks depends on how you manage your forces between defense and attack.
Build your forces
You can rescue people captured by the worms to make them refugees, then arm civilians by producing armies and turning them into soldiers. Soldiers are basic attack units: they attack nearby worms and can also fight worms near the base to obtain energy. Cannons, produced by the armory, deal heavy damage to the worms.
Units and upgrades
Engineering Airplanes can be converted into energy from trees in the worms’ forests during battle. This energy can upgrade any kind of building. Mecha commanders defend against worm attacks and deal heavy damage with mechas produced by the base; they can also lead armies in attacks on the worms.
