Serious Sam: Siberian Mayhem has appeared on the gaming horizon — a new adventure that has become an independent expansion of the Serious Sam 4 universe. The project was developed by the Russian Timelock studio, which gave fans not just another portion of crazy action, but a real journey into the icy heart of Siberia.
The player has about six hours to break through the snowy wastelands with the indefatigable Sam, destroying endless hordes of Mental’s minions. Everything is used — from classic shotguns to experimental guns that turn enemies into colorful flashes of chaos. But the main thing here is not only the arsenal, but the atmosphere — the very mix of old-school shooter, drive and branded sarcasm, for which the series has been loved for decades.
Siberian locations are striking in scale: frozen shores, abandoned villages and industrial zones create a sense of a living but hostile world. Every shootout here is a test not only of accuracy, but also of endurance. And even though the mechanics are familiar, the gameplay remains exciting, and the dynamics are non—stop.
I’ve been through Siberian Mayhem and I can say: This is not just an “add-on for show.” This is a concentrate of pure action, where snow crunches underfoot, explosions rumble on the horizon, and the player feels like an action hero from the golden age of shooters again.

When Serious Sam was released in 2001: The First Encounter, the shooter industry has experienced a real revolution. Against the backdrop of Quake and DOOM, where players wandered through narrow corridors and enclosed arenas, and even Duke Nukem 3D with its compact levels, the project by Croatian studio Croteam looked like a fresh breath of air. For the first time, the hero was released not into dark dungeons, but into spacious, at that time, simply gigantic, open locations.
The battles under the scorching sun and the endless fields through which hordes of alien creatures had to be shot gave an incredible feeling of freedom and excitement. I especially remember the branded opponents — headless kamikazes, whose screams became a meme within a couple of days after the release. The community quickly embraced the game with delight: The First Encounter was called “an old-school inspiration,” and journalists awarded it the title of one of the best games of the year. The success was resounding — and Croteam immediately set about continuing.
However, the sequels came out mixed. The quality of the content ranged from excellent to controversial, and sales stopped breaking records. As a result, there was an almost ten-year pause between the third and fourth installments of the series.

When Serious Sam 4 finally appeared in 2020, fans greeted it with mixed feelings. On the one hand, the long—awaited return of the iconic shooter, on the other — noticeably outdated graphics, a strange scenario and a swarm of technical bugs. In some places, the project looked more like a relic from the past than a modern game.
Nevertheless, the core of the gameplay remained unchanged — and that’s what saved the situation. In an era when most studios were trying to complicate the mechanics, Croteam went against the trends and created an extremely old-school shooter where everything is simple: take a weapon, go out into the field and mow down everything that moves. Not everyone liked this approach, but true fans of the classics appreciated the loyalty to the spirit of the series. No wonder Serious Sam 4 received 83% positive reviews on Steam — a decent result for a game that is not afraid to be itself.

The plot of Serious Sam: Siberian Mayhem
The events of Serious Sam: Siberian Mayhem unfold between the final missions of Serious Sam 4, creating a bridge between key points in the main story. This time it all starts with betrayal: one of the generals of humanity defected to the enemy, captured Sam and headed to the Tunguska portal to help the armies of the Mental finally enslave the Earth. But, as always, our hero is not one of those who can be held for a long time. He manages to escape in the middle of the snowy Siberian wasteland, arm himself to the teeth and go in pursuit of the traitor — straight to the epicenter of the invasion.

In fact, the plot of Siberian Mayhem can be described briefly and honestly.: “Sam goes ahead and crushes everything that moves.” But behind this simple description lies a surprisingly colorful journey through snowy Russia. Along the way, there are abandoned villages smelling of old carpets and homemade preserves, wooden churches with cracked icons, and partisans who speak broken English but defend their native land from monsters with iron determination. The atmosphere here is both absurd and charmingly familiar — like a brutal action movie with a touch of folklore.
The opponents, as befits the canons of the series, come in waves. Thousands of enemies are attacking from all sides, and every firefight turns into a pyrotechnic spectacle: orange flashes, the roar of a double-barrelled shotgun and crisp snow underfoot. This is the kind of old—school action game where the main thing is adrenaline and drive, not philosophy.
If we consider Siberian Mayhem as a part of the common universe, then it is rather a filler episode – a short but energetic addition that does not pretend to reveal the secrets of the Mental or deep drama. Yes, there are funny supporting characters, fleeting scenes with the characters of Serious Sam 4 and some new dialogues, but key plot revelations are not worth waiting for. However, that’s exactly what fans appreciate about the series: not for the storytelling, but for the clean, crazy gameplay, where every encounter is a celebration of chaos.
Gameplay Serious Sam: Siberian Mayhem
Serious Sam: Siberian Mayhem doesn’t try to rethink the series — and that’s its strength. The formula is the same as it was twenty years ago: Sam enters a spacious arena, where dozens or even hundreds of enemies rush at him. The player can only shoot in all directions, dodging between explosions and roaring monsters. At first, these are harmless opponents, but with each new location, the bestiary is replenished with fresh creatures, turning every encounter into a storm of adrenaline and drive.
All the old acquaintances gathered here again: skeletons of the Clear, headless kamikazes, biomechanoids, gnars, reptilians, werewolf bulls, clones with shotguns, drones and a whole horde of aggressive creatures that seemed to have escaped from nightmares and science fiction at the same time. Each opponent is deadly, but each one is destroyed with pleasure — especially if you use your arsenal wisely. You need to juggle guns here at least as often as you need to reload: from a distance — a crossbow with a sniper scope, at medium range — a pair of AK-47s, and in close combat — proven double-barreled shotguns.
As in the classic parts of the series, each shootout is a pure meat grinder in which the brain rests and the hands do their job. However, you will not be able to relax: The difficulty sometimes reaches extreme levels. Timelock developers do not spare the hero — they will lock him in a narrow corridor, where monsters will come wave after wave, or throw him into the arena, where hundreds of kamikazes will run literally in seconds. These moments make you sweat and give the action movies a special flavor.
But it was not without disappointment. Despite the new surroundings, the enemies have remained the same, and the updated arsenal is essentially cosmetics. Instead of a Kalash machine gun, a sniper crossbow is now used instead of a rifle. I would like to see more local details — say, bears instead of bulls, an axe instead of a knife, or at least unique traps reflecting the Siberian atmosphere.

The character’s leveling system migrated here unchanged from Serious Sam 4. At the start, Sam is an ordinary shooter, but once you collect a few artifacts, he turns into a machine of destruction: replenishes health with finishing moves, performs spectacular fatalities and shoots Macedonian with two hands. The problem is that the structure of the perks has remained the same — as many as four skills are dedicated specifically to two-handed shooting, and this feels like a missed opportunity to refresh the mechanics.
To survive the battles, the player should master several key mechanics:
-
Change weapons according to the situation — a crossbow for long-range, a double-barrelled shotgun for close combat.
-
Use finishing moves to restore health during combat.
-
Keep an eye on your surroundings — many arenas contain traps and shelters.
-
Save your ammo: it’s worth its weight in gold in Siberian Mayhem.
-
Don’t stand still — movement and constant rhythm save better than any shield.
Level design is another sore point. The maps are huge, but they’re a bit empty: exploring the far corners, you rarely find anything valuable. Sometimes even the “secrets” are disappointing — after a difficult parkour, Sam gets not a unique bonus, but a standard armor for ten points. Visually, the world looks interesting, but the rewards for exploration are minimal.
The bosses didn’t come as a revelation either. In most cases, they are simply enhanced versions of normal enemies with increased health or an additional technique like teleportation. The exception is the final boss, whose fight really leaves a pleasant aftertaste and makes the ending more complete than in Serious Sam 4.
Fortunately, the project is generous with vivid action scenes. To sit in a combat mech with a rocket launcher and a chainsaw, to smash crowds of monsters to the epic cover of “Kalinka-Malinka” — it’s hard not to smile. It’s that crazy, explosive spirit that the series is loved for.
But not everything was successful. Snowmobiling is one of the most controversial decisions. The controls are still clumsy, and the developers, as if out of spite, force them to arrange whole shootouts on the transport. As a result, these moments are more annoying than they add variety.
In general, the gameplay of Siberian Mayhem can be described as a classic old-school shooter with a slight touch of fatigue. Yes, there are few innovations, yes, some elements are drawn from the past, but what fans love about the series is preserved here: a frenzied rhythm, crazy shootouts, a sea of enemies and a feeling of pure chaos. Five levels fly by in about six hours, but this is six hours of real madness, where there is not a second of boredom.
