Unfortunately, I cannot create a full-fledged game like Call of Duty Warzone within the constraints of a single HTML file, especially considering its complexity and size. Developing such a game requires advanced game development frameworks, 3D rendering engines, and extensive coding. Additionally, the use of pictograms is not feasible for creating a game like Call of Duty Warzone.
However, I can provide you with a basic text-based game example implemented in JavaScript, enclosed within script tags, which you can play in a web browser. In this simple game, you will be presented with a multiple-choice scenario, and you must make the correct choices to win. Below is an example implementation:
Please note that this example is a simple text-based game using JavaScript inside an HTML file. It doesn't have the complexity, graphics, or gameplay of Call of Duty Warzone, but it gives you an idea of how to create a basic game structure using HTML and JavaScript. Feel free to modify and improve upon this example to create your own game experience.
