The ranking system was based on a player’s performance and outcomes in matches. Players started with a provisional rank, and through wins and losses, their rank would adjust. The season featured a series of competitive matches where players could climb the ranks. A significant aspect of Season 01 was the introduction of the Competitive Play Points (CP) system, where players earned points based on their performance. These points could be used to unlock special rewards, such as golden guns and sprays.

The inaugural competitive season of Overwatch introduced players to a ranking system that would categorize them into seven ranks: Bronze, Silver, Gold, Platinum, Diamond, Master, and Grandmaster. The competitive play format required teams of six players, divided into two teams of three: offense, defense, and two support players, though the support role quickly evolved to typically include two dedicated support heroes.

The first competitive season of Overwatch was a pivotal moment in the game's history, establishing it as a major player in the esports industry. It introduced a competitive ranking system that engaged players worldwide, fostering a vibrant community and professional scene. Through continuous support with patches and events, Blizzard Entertainment set a strong foundation for Overwatch, leading to years of competitive play and evolution.

Throughout Season 01, Blizzard Entertainment released several patches aimed at balancing the game and enhancing the competitive experience. Notable patches included adjustments to hero abilities, maps, and gameplay mechanics. For example, early patches addressed concerns with certain heroes being overpowered, such as Widowmaker and Reaper, leading to a more balanced meta as the season progressed.
