You are a cloud operator. In the game, to protect the core and resist the continuous virus invasions, you build defenses, construct cards, install creatively designed plugins that provide you with various attack methods, repair external nodes, and at the same time offer you more convenient defense.
Questions
Is it really free?
Yes. 核心防线 core defense line Demo is free right now on Steam, with nothing to pay.
Is this the full game?
No. A demo is a portion of 核心防线 core defense line Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.
Where do I claim it?
On the official Steam page. We link straight there — we never host game files or act as a middleman.
