Sure, here's a sample implementation of a text-based game representing a Three-dimensional World of Ultra-Violent Deathmatch Pro Wrestling Company called "Combat Zone Wrestling" using JavaScript enclosed in script tags in a single HTML file:
Combat Zone Wrestling
In this game, there are two characters represented by pictograms (player and opponent). When you tap/click on either character, they will perform an attack or defend action, and a message will be displayed indicating the action taken. The characters will return to their normal state after 2 seconds.
Note: This is a simple example and can be expanded upon to include more gameplay mechanics, scoring, and enhanced graphics/audio.
