How a student built a competitive multiplayer version of the classic arcade game Asteroids
At the 2019 CS50 Fair, Matt Thomas Pauly showcased Multiplayer Asteroids, a browser-based game that evolves the classic arcade experience. By integrating real-time competition, players do not just blast space rocks for high scores; they actively battle one another in a shared digital arena, pushing the boundaries of traditional single-player mechanics.
The CS50 Fair serves as the final showcase for students completing Harvard University's introductory computer science course. This program focuses on teaching students how to think algorithmically and solve complex problems efficiently. Participants gain exposure to a wide range of technical skills, including abstraction, data structures, resource management, and software engineering, while working with languages such as C, Python, SQL, HTML, CSS, and JavaScript.
Multiplayer Asteroids, developed by Matt Thomas Pauly, stands out as a creative application of these core programming principles. Unlike the original arcade version, which was strictly a solo endeavor, this project utilizes a Node.js-based architecture to facilitate a multiplayer environment. By leveraging web technologies like HTML, CSS, and JavaScript, the game allows multiple users to inhabit the same virtual space simultaneously. The primary objective remains the destruction of asteroids, but the addition of player-versus-player combat introduces a new layer of competitive strategy.
This project exemplifies the course's emphasis on building functional, interactive tools. While many students develop utility-focused applications—such as solar calculators, roommate coordination hubs, or cryptocurrency trackers—Multiplayer Asteroids demonstrates the potential for applying fundamental programming logic to real-time gaming. The project highlights how students can move beyond basic data manipulation to create engaging, networked experiences that require managing state and user interaction in a live browser setting. It remains a notable example of how the art of programming can be used to modernize classic concepts for a connected audience.
