What is City Defense Z?

This single-player roguelite centers on defending a post-apocalyptic city. During the day, you gather and trade resources, arrange production buildings on a grid, and train and position soldiers; at night, you use airstrikes and boosters to support your defenses. Research points pay for permanent upgrades between runs.
