Something has shifted in horror gaming. The genre spent several years being propped up by indie studios while the big franchises either went quiet or misfired. That wait is over. Resident Evil Requiem launched earlier this year to strong reviews, Silent Hill: Townfall has a confirmed release window following its reveal at June’s PlayStation State of Play, and Summer Game Fest 2026 surfaced a Resident Evil reimagining that Capcom describes as a key moment retold. By any measure, this is one of the strongest years the horror genre has seen.
What makes it interesting is not just the volume of releases. It’s the quality of the tension. The best horror games have always worked because they do something measurable to you. Your palms sweat. Your breathing changes. Your heart rate climbs. Research published by Casinos.com, a leading authority on Gigadat casinos in Canada, put numbers to exactly that, using heart rate monitors to test 14 gamers across 16 of the most popular and demanding titles on the market. The results confirmed what anyone who has fought a Dark Souls boss at 1am already knows: some games are genuinely physiologically stressful in a way that few other entertainment formats can match.
What the Data Actually Shows
The study measured resting heart rates as a baseline and then tracked BPM readings every ten seconds across 30-minute sessions. The average BPM increase across the full session gave a ranking of sustained stress. Peak BPM during the most intense moments gave a separate ranking of acute stress. The two tables tell different stories, and both are worth understanding as horror season ramps up.
Dark Souls III topped the peak stress table by a wide margin. When participants faced the Darkeater Midir boss encounter, heart rates hit 127 BPM, a 98.44% increase over the group’s resting baseline of 64 BPM. That number is startling. It puts a FromSoftware boss fight in the same physiological territory as moderate cardiovascular exercise. Fall Guys came second in the peak category at 95.11%, which says something about how much the format of timed elimination rounds can spike the body’s response even in a game that looks deceptively cheerful.
The sustained stress table produced a more surprising result at the top. Mario Kart raised average heart rates by 32.81% across the full 30-minute session, the highest average increase of any game tested. FIFA came second at 31.25%, followed by Call of Duty at 29.69% and Dark Souls at 28.13%. The data suggests that sustained competitive tension, the kind that comes from a race or a multiplayer match that goes all the way to the wire, produces a different kind of stress response than the sudden shock of a boss encounter. Horror games tend to dominate the peak category. Competitive games dominate the sustained one.
Why This Matters for the Horror Revival
The horror games arriving in 2026 are being built specifically around that peak stress response. Resident Evil Requiem, which follows FBI analyst Grace Ashcroft returning to a reimagined Raccoon City, has been designed with what Capcom describes as uniquely thinking enemy AI, creatures that adapt to player behaviour rather than following scripted patrol routes. That design philosophy is precisely what drives extreme heart rate spikes: the sense that the threat is unpredictable and present rather than memorisable and avoidable.
Silent Hill: Townfall, developed by Screen Burn (formerly No Code), takes a different approach. The studio behind Observation and Stories Untold has talked about weaving psychological horror into every layer of the game, including sound design, UI, and visual language. That kind of sustained atmospheric dread maps more closely to the sustained stress category in the data. It is less about jump scares and more about keeping the baseline elevated for the entire session, which is arguably the harder achievement.
The distinction matters for players choosing what to play. If you want the physiological equivalent of a sprint, a FromSoftware title or Resident Evil Requiem will deliver it. If you want something that grinds on you more gradually, the psychological horror revival currently underway in the indie space, and in the new Silent Hill entries, is engineered for exactly that response.
The Broader Pattern in Gaming Stress
One of the more counterintuitive findings in the research is what came at the bottom of the table. Animal Crossing, The Sims, and Skyrim all lowered average heart rates during 30-minute sessions, by as much as 5%. The games that players often describe as relaxing are measurably so. That seems obvious until you consider that it has implications for how people structure their gaming time, using high-stress competitive or horror sessions alongside deliberately low-stakes ones as a kind of palette cleanser.
The same pattern holds across online gaming platforms more broadly. The platforms that retain players longest tend to be those offering the widest spread of experience types rather than optimising for a single register. Variety across intensity levels allows players to manage their own engagement, moving between the acute stress of a boss fight and the decompression of something slower and more exploratory.
What to Play When the New Releases Land
For players who want to track the horror revival as it unfolds, the release slate through the rest of 2026 gives plenty of options at different points on the stress curve. Resident Evil Requiem is the obvious entry point for players who want the full physiological workout. The franchise has a proven track record of producing exactly the kind of acute stress spikes the data captures, and this entry has been built with more reactive AI than previous instalments.
Silent Hill: Townfall is the more interesting proposition for players who want sustained dread rather than sudden shocks. The studio’s previous work has consistently used environmental storytelling and sound design to create a sense of unease that accumulates rather than detonates. If the heart rate data is a useful guide, expect it to sit higher on the sustained stress table than the peak one.
The revival also has a strong indie component. Re:animal, described by developers as a more psychologically intense take on the Little Nightmares format, is already available. The Road of Dust and Sorrow, a pixel art survival horror title drawing on classic genre touchstones, is also on the horizon. For players who find the blockbuster entries overfamiliar, the indie half of the revival is where the genre is taking its most interesting structural risks.
Horror gaming has always been the genre most willing to experiment with how fear actually works on a physiological level. The data behind the current revival suggests those experiments are landing. Your heart rate will confirm it.
