How many GB is Air Defender?

1 GB

That is less than the typical Real Time Strategy (RTS) game, which needs about 6 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

TAKE COMMAND OF THE NATION'S AIR DEFENSE The sky is your battlefield. A hostile contact appears on radar. Is it a civilian airliner off course, or the prelude to a full-scale attack? Your job is to find out. Air Defender is a high-stakes, real-time strategy simulation that puts you in the command chair of a national Air Defence network. From a top-down strategic view, you are the unseen hand responsible for detecting, identifying, and intercepting airborne threats. This is not a dogfighting game; you are not a pilot. You are the commander with access to the capabilities of multiple roles in the bunker, and the fate of the nation rests on your split-second decisions. Analyse radar returns, scramble your Quick Reaction Alert (QRA) fighters, and manage your assets to protect your airspace. Every choice matters, and the consequences of failure are devastating.
