As an AI language model, I can provide you with a basic framework for a text-based Titanfall 2 game that you can further enhance with pictograms and styling to make it suitable for mobile devices. Please note that this HTML code is just a starting point, and you may need to incorporate appropriate JavaScript functions to make it functional as a game.
Please note that this code structure provides a basic layout for the game. You will need to build upon this by defining game mechanics, graphics, controls, and other features to create an interactive game experience. Feel free to modify and expand the code as per your requirements.
