As an AI text-based assistant, I can provide you with a sample code for a simple text-based World War 2 game that you can include in a single HTML file. Since this response is limited to plain text, I won't be able to use pictograms or provide a complete game experience, but I can demonstrate how the game logic could work. Here's an example game implementation in JavaScript:
In this sample game, the player and the enemy start with 100 health points each. The `attack()` function simulates a round of combat, with both the player and enemy randomly attacking each other with a damage range of 1 to 10. The game ends when either the player's or the enemy's health reaches zero or below.
You can extend this code to include additional game elements, such as player input, a graphical interface, or more complex game mechanics.
