Steel Umbrella

Air defense strategy

Steel Umbrella is a PC real-time air defense strategy game set on a satellite map of Earth. You protect a city from drones and missiles by placing launchers, nets, and radar during the day, then managing the defense when attacks arrive at night. The goal is to survive ten nights.

The day-night cycle follows the real globe. During daylight, you plan where to put defenses and which sites to leave exposed. Once night falls, the layout is fixed; only your mobile machine-gun crews can move during the raid. Damage carries over between nights, and repairs happen at dawn.
