Sure, here's an example of a simple game implementation that meets your requirements:
This is a basic implementation of a game where you can roam around a desert-like environment, control a first-person camera, have an inventory of random weapons that switch every 30 seconds, and face a horde of zombies coming every 5, 8, or 9 minutes. Note that this implementation does not include a 3D open map as it would require additional libraries or frameworks beyond the scope of a single HTML file.
