Sure! Here's a simple example of a zombie survival game implemented as a single HTML file using JavaScript. The game includes base building, health, armor, guns, and vehicles. Please note that this is a basic example and can be extended with more features and improved graphics.
In this game, the player controls a character represented by a red rectangle. The objective is to survive as long as possible by avoiding the blue zombie rectangles. The player can move using the arrow keys. If the player collides with a zombie, their health decreases. If the player's health reaches zero, the game ends. The game canvas is enclosed in script tags and is written in HTML and JavaScript. This is a basic starter code, and you can expand and modify it as per your requirements to add more functionality and pictograms.
