What is Signal Zone?

Signal Zone is a single-player strategy game in a pixel-art, post-apocalyptic setting. You explore procedurally generated maps and mine during short days, then defend your base with walls and turrets at night, repairing damage between creature waves. You can play a campaign with specific objectives, an endless mode, or custom games.
