How Review Bombing Changed the Way We See Game Ratings
Pedro Faiole·
At some point you've probably looked at a game's review score and felt something was wrong. The number didn't match what your friends were saying, what you'd seen in trailers, or what every critic had written. The score felt like a signal from a completely different conversation.
That feeling usually means you were looking at a game that had been review bombed.
Review bombing is the coordinated practice of flooding a game's user reviews with negative ratings in a short window, typically in response to something that has nothing to do with the game itself. It's been reshaping how scores work since at least 2017, and platforms like Steam and Metacritic have spent years trying to figure out what to do about it. Whether they've succeeded is genuinely still an open question.
The Case That Made It Famous
The practice predates 2017, but September of that year is when it broke into mainstream gaming discourse. YouTuber Felix Kjellberg, known as PewDiePie, shouted a racial slur during a livestream. The backlash was immediate. Developer Campo Santo filed a DMCA takedown against PewDiePie's Firewatch video and announced they'd ban his channel from streaming their games going forward.
His fans responded by targeting Firewatch on Steam. The game's user score fell from "Very Positive" to "Mixed" within days. Nothing about the game had changed. No patch had broken it, no developer had said anything inflammatory, no business decision had angered the playerbase. Firewatch just happened to be the game in the crossfire.
That case forced a real question into the open: if user reviews can be weaponized against a game for reasons that have nothing to do with the game, what are those scores actually measuring?
Why People Organize These Campaigns
Researchers have been trying to answer that question more rigorously. A 2024 NLP study published on arXiv analyzed over 513,000 Metacritic reviews across 68 games showing signs of coordinated bombing. Using machine learning classifiers, the researchers could distinguish bombing-driven reviews from legitimate negative reviews with 88% accuracy, and they identified five recurring drivers behind the campaigns:
Driver
What it looks like in practice
Corporate grievance
Anger at major publishers (Blizzard, Activision) for business decisions unrelated to the game
Content backlash
Frustration with remasters, sequels, or shifts in creative direction
Economic complaints
Pricing, DLC costs, microtransaction systems
Betrayal language
High frequency of words like "false," "promise," "shame"
Extreme sentiment
Terms like "garbage" and "trash" appearing in concentrated bursts
One finding surprised people who assumed this was primarily a culture-war phenomenon: among PC game reviews, the study found minimal political or ideological language. Console-exclusive titles showed the opposite pattern. Platform matters a lot in terms of what actually triggers a campaign.
The European Video Games Observatory framed it this way in a 2025 analysis: the rise of user reviews, "often motivated by emotional and moral considerations, seems to be overturning the historical dominance of professional criticism." Review bombing is the most dramatic expression of that shift. It's what happens when collective emotional energy gets channeled into a rating system that wasn't built for it.
How Steam Finally Responded
By 2019, Steam had become the main stage for major bombing campaigns, and Valve formalized a response. In March of that year, the company announced a system to detect and quarantine what it called "off-topic review bombs."
"We're going to identify off-topic review bombs, and remove them from the Review Score."
The mechanics: Valve's systems flag anomalous spikes in review activity. A human team then decides whether the spike looks like a genuine reaction to the game or an organized campaign about something external. If it's the latter, reviews from that window are excluded from the public score, though they remain visible to anyone who looks at individual reviews.
Valve drew the line at "off-topic" carefully. DRM changes, EULA updates, external creator controversies, and business decisions unrelated to gameplay all qualify as off-topic. A patch that breaks core functionality or a developer's own statements about their game don't.
There's an acknowledged cost: legitimate negative reviews posted during a bombing window get caught in the exclusion because reviewing each one individually isn't feasible. Valve called review bombs "temporary distortions" and argued the overall scores remain accurate enough. Critics of the policy note that Valve is now making editorial calls that weren't previously part of how the platform worked.
The key shift: Steam's user score stopped being a raw democratic count. It became a curated signal, filtered by a policy most players didn't know existed.

Helldivers 2: When Bombing Actually Won
Firewatch showed review bombing at its most random. The Helldivers 2 situation in May 2024 showed something else entirely: organized consumer pressure achieving a concrete reversal, in days, against a major publisher.
Helldivers 2 launched in February 2024 as a breakout hit, reaching over a million concurrent players on Steam. Its score was "Very Positive." Three months later, Sony announced that PC players would be required to link their Steam accounts to a PlayStation Network account by May 30.
The problem was immediate and real. PSN isn't available in 177 countries where the game had already been sold on Steam. Players who'd bought it legitimately faced losing access to something they owned. The requirement also arrived retroactively, months after purchase, without meaningful advance notice.
The community responded with a coordinated negative review push. Over 330,000 negative reviews arrived in three days, dropping Helldivers 2's rating from "Very Positive" to "Mixed," with recent reviews hitting "Overwhelmingly Negative" at just 14% positive. Steam temporarily pulled the game from purchase in affected regions.
Sony reversed on May 6, three days after the announcement. PlayStation issued a statement saying they were "still learning what is best for PC players" and that player feedback had been "invaluable." The mandatory requirement was dropped.
Arrowhead's community manager had actively encouraged the campaign, calling Steam reviews "a place where it might actually make a difference." It did.
What happened next complicated the story. Even after Sony backed down, and even after the community launched "Operation Clean Up" encouraging players to switch reviews back to positive, the game's overall score never fully recovered. It sat at "Mixed" for months. Future buyers with no connection to the original controversy would see that rating with no context for what it actually represented.
The review system had captured a protest, not an assessment of quality. Both things were true at the same time, and the score couldn't tell them apart.
What This Did to How We Read Scores
Review bombing didn't destroy rating systems. It made them much harder to read in isolation. A few things shifted permanently:
The aggregate isn't the whole story. A "Mixed" or "Mostly Negative" rating now prompts a follow-up question: why? You have to check whether the recent score diverges from the all-time score and whether there's an obvious external event that lines up with the timing. The number stopped being a verdict and became a starting point.
When reviews arrived matters. The all-time score averages years of feedback, including some from when the game was in a completely different state. The recent score is noisier but often more telling. Checking the review graph over time is now a basic literacy skill for anyone trying to make an informed purchase.
Platforms filter differently. Steam excludes verified off-topic bombs from its displayed score. Metacritic doesn't have an equivalent real-time system. What you see on one platform won't match the other, and neither gives you an unfiltered picture. You're not comparing apples to apples when you cross-reference.
This is part of a broader collapse of trust in aggregate scores that goes well beyond bombing. If you want the full picture of how gaming criticism went from authoritative to fractured, the Review Culture Evolution traces the whole arc, from magazine-era authority through the aggregation experiment to where things stand now.
The Trust Problem That Didn't Get Fixed
Here's the thing: the platforms addressed the mechanics of bombing without really solving the underlying problem. Steam can exclude a flagged time window from its score, but it can't retroactively repair the reputation of a game whose "Mixed" rating has been baked into the algorithm for years. It can't give context to a potential buyer who doesn't know the history.
And the cases where bombing is actually justified, in the sense that the community has a legitimate grievance about a real business decision, don't fit neatly into "off-topic." The Helldivers 2 situation involved a real, concrete harm to real players in 177 countries. Calling that off-topic would have been its own kind of distortion.
What this means practically: the scores you see on any platform are now mediated in ways that aren't transparent. Valve's team decides what qualifies as off-topic. The ratings that survive are the ones they didn't flag. You're trusting the filter as much as you're trusting the crowd.
Reviews You Can Actually Trust
The gaming community's response to all of this has been more sophisticated reading habits, which is something. Players who've followed the space closely have learned to cross-reference, to look for context, to treat any aggregate number as provisional. That's fine as far as it goes, but it's extra work every time you want to know if a game is worth buying.
The reviews that actually age well aren't the ones with the most votes. They're the ones where you know the reviewer: their taste, their history with the genre, whether their recommendations track with games you've loved or hated. That kind of context only builds up over time, and only when people write it down somewhere it can actually be found.
If you want your opinions to carry weight, not just right now but two years from now when someone else is trying to decide whether a game is worth their time, you need a place to build that record. Browse and log the games you've played on The EndWiki, write reviews that capture what you actually thought, and build a history that means something beyond any single crowdsourced score.
The aggregate is noisy. Your own record doesn't have to be. Create your free account on The EndWiki and start writing reviews that reflect what you actually think, separate from whoever happened to be running a campaign the week a game launched.
