Overwatch: The Defining Hero Shooter, from Origins to Today
How Blizzard's Overwatch rose from a canceled project, its hero, role, and objective gameplay, its awards, and its path through Overwatch 2 to today.
Overwatch is a team-based first-person shooter released by Blizzard Entertainment in 2016. Each player picks one of many "heroes," each with unique abilities, and fights alongside teammates over objectives such as capturing points or escorting a payload. Because choosing which heroes to use and how to combine them matters as much as shooting skill, it's often mentioned alongside the genre name "hero shooter."
In this post, we cover how Overwatch began on the remains of a failed project, the rules by which the game actually works, why it won so many awards, and its journey from becoming Overwatch 2 in 2022 to returning to the name "Overwatch" in 2026.

The original game ended service in October 2022 and was replaced by its sequel, Overwatch 2. In February 2026, Overwatch 2 was renamed back to "Overwatch" and is still in service today. Wikipedia sometimes refers to the 2016 original separately as "Overwatch Classic."
Origins
Overwatch began with Blizzard's cancellation of "Titan," a large MMORPG it had been working on for a long time. Titan had been in development for about seven years, and after its cancellation most of the staff moved to other departments. The remaining small team of about 40 people, led by director Jeff Kaplan, had to come up with a new game idea within a few months.
Taking cues from team-based shooters like Team Fortress 2 and the popularity of the AOS (MOBA) genre, where you pick a hero to fight with, the team settled on the direction of a "hero-centered team shooter." They showed a prototype using some assets built for Titan and received approval for full development. Overwatch became Blizzard's first new intellectual property (IP) since StarCraft.
The game's world also connects to this experience. Drawing on the mood after their project collapsed, the developers chose to depict a hopeful near future instead of a dark dystopia. The premise, in which former agents reunite after the disbanding of Overwatch, an international organization that ended a war with the robotic "Omnics," created a bright, colorful stage featuring diverse characters from many countries, robots, and even a gorilla.
The game was first revealed at BlizzCon on November 7, 2014, where attendees could play it on the spot. After a closed beta in October 2015, about 9.7 million people took part in the open beta in May 2016.
Gameplay
The basic format is a 6v6 team battle (5v5 from Overwatch 2 onward). Heroes are divided into three roles.
| Role | What they do |
|---|---|
| Tank | Absorbs damage with high health and barriers to create space. |
| Damage | The main firepower for killing enemies and attacking or defending objectives. |
| Support | Heals allies or boosts their abilities. |
Each hero has a basic attack, several abilities, and an "ultimate" that charges as you deal damage or heal. You can switch heroes mid-match, so adapting to the enemy team's composition is a key strategy.
Main modes include "Control," where you capture and hold points; "Escort," where the attacking team pushes a payload to its destination while the defending team tries to stop it; and "Hybrid," which combines the two. There are Quick Play and ranked Competitive Play, along with seasonal events and Custom Games where players set their own rules. Loot boxes earned by leveling up contained only cosmetic items that change appearance, so they had no effect on abilities. The hero roster grew from 21 at launch to 32 by April 2020, and all new heroes and maps were added through free updates.
Why It's a Classic
Overwatch received very high praise from critics right after launch. Frequently mentioned strengths include:
- A low barrier to entry. Even players with weaker aim can contribute to the team by putting up barriers or healing allies, so it was praised as a game newcomers and veterans can enjoy together.
- Appealing characters and world. Unlike war shooters dominated by browns and grays, its bright, cartoon-like art style and heroes with distinct nationalities and personalities became the face of the game. The story was told mainly through animated shorts and comics rather than in the game itself.
- Depth of team composition. Thanks to hero swapping and role division, each match plays out differently even on the same map.
Its achievements were clear as well. It was named Game of the Year in 2016 at The Game Awards, the D.I.C.E. Awards, and the Game Developers Choice Awards. Blizzard said its first-year revenue exceeded $1 billion, and three years later it had more than 50 million players. In Korea, figures in June 2016 even showed it overtaking League of Legends in PC bang usage share.
Of course, there was criticism too. Some pointed out that toxic behavior between players grew after Competitive Play was introduced, and the near absence of story within the game was also seen as a shortcoming.
The Series and Its Influence
Overwatch also expanded greatly into esports. The Overwatch World Cup, a national team competition, was held in 2016, and Blizzard created the "Overwatch League," made up of city-based teams, which ran from 2018 to 2023. Twelve teams from North America, Europe, and Asia took part in the first season.
The sequel, Overwatch 2, was announced in 2019 and released in early access on October 4, 2022, with the original's servers shut down the day before. Key changes include:
- Team size dropped from six to five, with only one tank per team.
- The game became free-to-play, and seasonal battle passes replaced loot boxes.
- New modes were added, such as "Push," where two teams race to push a robot.
The story-driven co-op mode announced alongside it was scaled back in 2023. Then in February 2026, Blizzard renamed the game back to "Overwatch" and said it would run with yearly story arcs and seasons. Its structure of picking heroes and fighting as a team has influenced many shooters since, and it was one of the reasons the term "hero shooter" became widely used.
How to Play It Today
The 2016 original can no longer be played. Today, you can download and play the renamed current "Overwatch" for free. It's available on Windows, PlayStation 4 and 5, Xbox One and Series X|S, and Nintendo Switch, and a dedicated Nintendo Switch 2 version came out in April 2026. Cross-platform play is also supported.
If you're new, it's best to learn the abilities of a few heroes you like first, then start with unranked Quick Play. Each role has a very different character, so learning one role at a time keeps things manageable. If you're curious about the 6v6 format of the original, it's worth noting that in July 2026 the developers announced a new experimental 6v6 mode.
