About Green Valley Defense
Green Valley Defense is a bright, friendly tower defense game where a fleet of chubby flying saucers wants to land on your peaceful kingdom. A dusty road winds through the meadow from the western woods to your blue-roofed castle, and every grassy plot along it is a place for a tower. Tap a plot and a ring of four choices opens: the purple ballista fires quick bolts that also hit flying saucers, the red cannon lobs heavy balls that blast whole groups on the road, the frost spire coats saucers in ice so they crawl, and the tesla coil sends lightning jumping from one ship to the next. Each kill pays gold, and gold buys more towers or upgrades that make them taller, stronger and longer ranged. Fifteen waves arrive one after another, and you can call the next wave early with the red button at the road entrance for bonus coins. Scouts come first, then speedy darts, armoured tanks, high-flying saucers, and finally a huge mothership with a glowing beam. Twenty lives protect the gate. Keep all of them and you earn three stars. It is the perfect first map: gentle at the start, with coach marks showing where to build, but it still asks for real planning once the waves get crowded.
How to play
