Compare Serious Sam: Siberian Mayhem prices across trusted key stores and find the best deal. Developed by Croteam. Published by Devolver Digital. Released on 1/25/2022. Available on PC, Xbox. Genres: Action, Adventure. Metacritic score: 70/100.

If your idea of a good time is strafing backwards while firing a minigun into a wall of headless screamers, Siberian Mayhem is five levels of exactly that, tuned tighter than its parent game and priced to match.

I went in half-expecting a mod with a price tag stapled to it. What I got was something more honest than that. Siberian Mayhem started life as exactly that, a passion project from Timelock Studio, a crew of Russian Serious Sam modders who submitted an 80-page design document to Croteam and somehow got greenlit. That origin story matters, because the game carries the specific enthusiasm of people who knew the series better than its official custodians did in places, and it shows in the level design. The campaign spans five large levels set across frozen Siberia, from oil refineries and arctic coastlines to desolate taiga forests and abandoned villages. Blizzards roll in mid-combat and chew up your visibility, and staying in icy water long enough will start draining your health. These are small details, but they make the environments feel purposeful rather than just scenically cold. The structure is pure old-school: run toward the objective, trigger a horde, survive, repeat. Side quests branch off the critical path and reward exploration with weapons and gadgets you will not find otherwise. The T.A.C.T. airstrike, the XPMR Burner Raygun that superheats enemies until they detonate, and the SBC Cannon ripped from a pirate ship are the kind of discoveries that make side content worth the detour. Three new weapons join the full suite carried over from Serious Sam 4: the AK-74MX assault rifle, the TCC-2 Perun crossbow for longer sightlines, and that Burner Raygun. New enemy types include the Draconian Burner, which jets around on a big pack while hosing you with thermal beams, and the Octanian Sentry Tower, a stationary nightmare that tracks you with drones and missile volleys from across the map. Enemy variety is genuinely good, and the game quietly demands weapon switching in a way that stops the shooting from going brain-dead. The S.A.M. ability system lets you unlock perks like melee takedowns on larger enemies or, brilliantly, the option to ride them. New Game+ deepens the loop considerably, adding weapon upgrades and exponentially escalating enemy counts for players who want to keep pushing. The honest criticisms land the same way they did for Serious Sam 4: performance wobbles at times, pop-in is visible, and the visuals sit somewhere behind the current technical curve. The campaign clocks between five and six hours on a focused run, more if you dig into side content, and critics were split on whether that runtime justifies the standalone price. The opening hour is also rough before your arsenal fills out. Starting with a pistol against a swarm of Gnaars is not the game at its best. Stick with it and the sandbox opens up in satisfying ways. Online co-op is supported and scales enemy spawns accordingly, which nudges the whole thing firmly into the "better with a friend" category if you have one on hand. What Siberian Mayhem does exceptionally well is pacing. It does not overstay its welcome. The horde loop ends before it sours, the side quests break the rhythm at sensible intervals, and the boss encounters introduce mechanics you do not see elsewhere in the campaign. For players who bounced off Serious Sam 4 due to pacing problems, this is the leaner, better-edited version of that same engine and tone. For players new to the series entirely, it is a clean entry point that requires no prior knowledge to enjoy. Alex, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
