Various unfinished iterations of Half-Life 2 have emerged over the years, showcasing the evolution of Valve's vision for the game. A recent video by YouTuber CMDR RileySV explores the 2003 beta, focusing on the "City 17 river," which was originally intended to play a significant role in the gameplay. In the beta, players would navigate through canals leading to the Citadel, promising a striking visual reveal. Although remnants of these elements exist in the final version, the canal section was repurposed, leading to mixed player reactions. A comment from user @FlintExp highlights that the city layout of City 17 draws inspiration from New York City, with specific coordinates matching real locations. The river was once a crucial aspect of the journey through City 17, guiding players toward the Citadel. The 2003 beta closely resembles the retail version, with notable differences reflecting Valve's editing process before release.
