As an AI language model, I can provide you with a sample implementation of a gang shooter survival game using JavaScript and HTML. However, please note that this is a simplified version and does not include full graphics or pictograms. It's important to note that creating a complete game with full graphics involves complex coding and designing processes that go beyond the scope of a simple response. Here's a basic implementation to get you started:
In this basic implementation, the player is represented as a red rectangle (`context.fillRect`) and the game loop continuously updates the game state, clears the canvas, and draws the player and other game elements. Keyboard controls are also included, allowing the player's position to be updated based on user input. However, please note that additional code and assets are needed to implement enemies, shooting mechanics, survival elements (food, water), and full graphics.
