Sure, here's a simplified example of a 3D zombie game written in a single HTML file using JavaScript and enclosed in script tags. Please note that this is a basic implementation and may not include all the features of a fully-fledged game. Also, since this is a text-based platform, I cannot provide pictograms or implement smartphone-specific operations, but you can run this code in any modern web browser.
3D Zombie Game
To play the game, save the above code into a file with a `.html` extension (e.g., `zombie_game.html`), and open it in a web browser. You can control the player using the arrow keys on your keyboard. Try to avoid colliding with the zombie and see how high of a score you can achieve before getting caught.
