Nuclear missiles are raining down two cities, and your silos are the only defense against impending doom. In Silent Earth, you "connect" to those silos through your phone and tactically use different weapons to fight back.
As incoming missiles streak across the screen, you activate different silos to intercept them. Each silo has a unique ability - a shockwave push, a horizontal spread of barriers - and can be combined in tactical ways. Using the aforementioned weapons together let you create a spreadshot to protect a wide area.
Managing your ammo and trying not to overheat your weapons will be crucial to surviving the apocalyptic artillery.
As you survive longer, and face powerful bosses, you'll also uncover hidden text and audio files through an in-game browser that lets you unfold Silent Earth's narrative through logic puzzles and sleuthing.
