This game is called "Warzone 2100". It is a real-time strategy game, originally developed by Pumpkin Studios and published by Eidos Interactive, now developed by the Warzone 2100 Project. Compared to other real-time strategy games, it has a greater focus on artillery, radar, and counter-battery technologies, more frequent in-game cinematic updates as game play progresses, a massive research tree, as well as a vehicle design system.
In the late 21st century, NASDA (the North American Strategic Defense Agency) developed and deployed a massive missile defense system, including a network of nuclear-equipped satellites and ground-based launch sites. However, during a routine maintenance check, something went terribly wrong.
