Doom Veterans Debate the Origins of Deathmatch's Rise

Few games have a legacy as secure as Doom. The 1993 first-person shooter helped define the speed, spectacle, technical ambition, and modding culture associated with PC games in the decades that followed. Its Deathmatch mode, meanwhile, became a foundational point in the history of competitive multiplayer shooters. Yet even with Doom's place in the medium firmly established, two people closely involved with making it are now publicly disagreeing over a key question: did the team expect Deathmatch to become a major success before the game launched?

Doom co-creator John Romero and designer Sandy Petersen, who worked on the game's levels and game design, discussed their differing memories in posts on X. Their exchange does not challenge what Deathmatch ultimately became. It instead centers on the mood within id Software during development, and whether the developers believed players would broadly embrace head-to-head play over the networking technology available at the time.

It is a revealing disagreement because game history is often told through clean, simplified stories. A groundbreaking game arrives, its makers immediately know they have changed everything, and the rest of the industry follows. Real development is usually less neat. Teams can hold competing views, change their minds over time, or remember the same meeting in sharply different ways years later. In Doom's case, the core outcome is beyond dispute: Deathmatch found an enormous audience and helped create the template that multiplayer first-person shooters would build on for years.

Petersen's memory of cautious expectations

The conversation began when Petersen shared a broader account of how Doom changed gaming. In outlining his career before joining id Software, he recalled work on the 1990 real-time strategy game Command HQ. Petersen described how designer Danielle Bunten Berry had expected that title's modem support could encourage substantial head-to-head play, given the number of players who had modems at the time.

However, Petersen said Command HQ did not become a major commercial success, estimating that it sold roughly 40,000 copies. That experience, he argued, shaped his thinking about multiplayer's likely reach. He then connected it to Doom's development, writing that the team generally felt few people would play Deathmatch other than in limited numbers. His recollection was that, despite this skepticism, everyone at the studio enjoyed playing the mode enough to keep it in the game. The assumption, in his telling, was that the developers themselves would at least have fun with it even if the wider public did not.

That is a plausible picture of an era when online gaming was far from frictionless. Modems, phone charges, setup hurdles, compatibility problems, and modest connection speeds made playing against someone outside a local network a different proposition from simply launching a modern online game. Multiplayer gaming existed, but it did not yet have the seamless, always-connected infrastructure now taken for granted.

Romero points to Doom's early multiplayer plans

Romero challenged Petersen's version of events directly but initially politely. He said the team had publicly announced multiplayer functionality in a press release dated January 1, 1993, eight months before Petersen joined the company. Romero's central point was that the studio had already been confident that multiplayer would matter, and that it had described the feature in unusually bold terms.

In that announcement, Romero said Doom's multiplayer was characterized as something that could become "the number one cause of decreased productivity in businesses around the world." For Romero, that language was not a casual promotional flourish detached from the development team's actual expectations. He said id Software knew Deathmatch would be huge and did not need to be persuaded that it had significant potential.

Romero also expressed concern about historical accuracy, arguing that Petersen's statement was readily contradicted by the company's earlier public messaging. He asked Petersen to be more careful when recounting Doom's history, particularly because the game and its development have been discussed so extensively over the years.

The disagreement then became more pointed. Petersen responded that he had no firsthand knowledge of decisions made before he joined id Software. He maintained that a discussion happened after he arrived in which he raised his experience with Command HQ, and in which Romero himself agreed that Deathmatch might not become a particularly large deal. Petersen said the team still wanted the mode and added that he was happy his prediction turned out to be wrong. He also pushed back against Romero's characterization of his account.

Romero replied that he did not believe Petersen's recollection was correct and said other members of the Doom team likewise disagreed with it. He reiterated that the developers understood Deathmatch's potential from the beginning, and that the mode's eventual reception validated those ambitions. At the time of the exchange, that was the latest public post in the discussion.

Two claims that may concern different moments

There is an important distinction at the heart of the debate. Romero's evidence concerns the game's multiplayer plans and the confidence expressed by id Software before Petersen arrived. Petersen's account concerns his memory of an internal discussion after joining the studio. It is possible for a company to market a feature with enormous confidence while individual developers, at another point in production, privately question how widely it will be used. It is also possible that one participant remembers a conversation very differently from another.

Neither possibility settles the matter. Romero is unequivocal that the team understood Deathmatch's importance from the outset. Petersen is equally clear that he remembers a later conversation marked by lower expectations. Without a complete record of every development discussion, observers cannot definitively reconstruct the exact sentiment of every person involved at every stage.

What can be established is that multiplayer was not an accidental late addition to Doom. It had been publicly discussed well before the game's December 1993 release. Doom shipped with cooperative play and competitive Deathmatch, bringing the game's ferocious movement, weaponry, level layouts, and monster-filled spaces into a new kind of social arena.

Why Doom Deathmatch became so influential

The word Deathmatch is now so common that it can feel generic, but Doom gave the term and the format lasting cultural force. Players could enter maps as adversaries, race for weapons and armor, learn item locations, exploit shortcuts, and turn familiar single-player spaces into competitive battlegrounds. The game's fast movement and immediate combat made each encounter memorable. A shotgun blast, rocket, or plasma burst could change the tone of a match instantly.

Just as importantly, Doom arrived at a moment when PC players were increasingly able to connect machines through local networks, serial connections, and modems. The practical barriers were real, but the appeal was immediate once matches began. Offices, college campuses, and home networks found reasons to arrange games. Doom's multiplayer inspired stories of time lost, work delayed, and friendships or rivalries formed through repeated matches.

The design also gave players a language for competition that subsequent shooters expanded on. Map knowledge mattered. Resource control mattered. Anticipating an opponent mattered. Mechanical accuracy mattered, but so did positioning and timing. Later games would refine network code, introduce dedicated servers, build formal ranking systems, and turn competitive shooters into global esports. But Doom helped demonstrate why the genre's basic loop was so compelling.

Its influence reached beyond any one technical feature. Deathmatch encouraged players to view a first-person game not only as a campaign to complete, but as a place to return to with other people. That shift became central to the future of shooters. Whether the connection happened across a room, a school network, or a phone line, the experience transformed the game from a solitary descent through demonic corridors into a contest shaped by human unpredictability.

A legacy larger than the disagreement

The Romero-Petersen exchange illustrates how difficult it can be to preserve the details behind landmark games. Developers are not archives. They are people recalling intense work completed decades earlier, often amid changing roles, competing priorities, rapid deadlines, and countless conversations. Public documents can clarify some points, but they cannot always capture the atmosphere of a studio or the precise context of a particular meeting.

For fans, the discussion is still valuable because it highlights the uncertainty surrounding innovations that later look inevitable. In 1993, Doom Deathmatch was not a familiar checkbox on a genre feature list. It was a bold use of emerging PC connectivity, attached to a game that was already pushing technical and design boundaries. Predicting exactly how players would respond would have been difficult, even for the people creating it.

Whatever the internal expectations were at different moments, the result speaks for itself. Doom's multiplayer became one of the most consequential features in shooter history, and its impact can be felt in virtually every competitive first-person game that followed. The debate may not produce a shared recollection, but it does underline a simple truth: Deathmatch was too important to Doom's legacy to be remembered as a minor detail.
