Single Player
Race through a historically inspired recreation of the Southern Polytechnic State University campus. The original single-player experience and environment were developed by the Fall 2025 capstone team.
Kennesaw State University • Spring 2026 Senior Capstone
Southern Bathtub Racing Game
Award-Winning Capstone | Unity • C# • GONet • Steamworks.NET
A multiplayer racing game preserving the history and spirit of Southern Polytechnic State University's legendary bathtub races. During Spring 2026, our senior capstone team inherited an existing Unity racing game and extended it with online multiplayer, improved racing AI, testing, technical documentation, and release preparation.
Technical Overview
The Spring 2026 team extended an inherited Unity codebase with multiplayer networking, platform integration, testing, and continued-development resources.

From Single Player to Online Multiplayer
The Fall 2025 capstone team developed the original single-player racing experience and game environment.
During Spring 2026, our team inherited the existing Unity codebase and extended it with online multiplayer functionality using GONet synchronization and Steamworks.NET lobby integration.
The team also improved the racing AI, tested multiplayer gameplay, expanded technical documentation, and prepared the project for continued development.
Real-World Engineering Experience
Working with an inherited codebase required the team to understand existing architecture before integrating new features—similar to maintaining and extending an existing application in a professional software-development environment.
Game Modes & Development
Online Multiplayer
The Spring 2026 team extended the project with online multiplayer. GONet provides game-state synchronization using a host/client architecture, while Steamworks.NET supports lobby integration for online races.
Racing AI
The Spring 2026 team also improved the computer-controlled racing opponents to provide more robust and competitive gameplay.

1st Place — Spring 2026 KSU C-Day
The Spring 2026 Southern Bathtub Racing Game team earned 1st Place in the Undergraduate Project Competition at Kennesaw State University's College of Computing and Software Engineering C-Day.
SPSU History
Preserving a Campus Tradition
From 1968 through 1991, bathtub racing became one of Southern Polytechnic State University's memorable student traditions. Student teams constructed racing vehicles using cast-iron bathtubs, lightweight engines, and their own engineering creativity.
The races brought students, faculty, alumni, spectators, and sponsors together around a uniquely Southern Poly combination of engineering, competition, creativity, and school spirit.
The Southern Bathtub Racing Game preserves that tradition through an interactive recreation of the event and the SPSU campus.
