Serious Sam: Siberian Mayhem Coming to Steam This Month

Sam Stone heads to Russia for frosty first-person shooting.

We just reviewed Serious Sam 4, a first-person shooter from Devolver Digital. While the recently released console ports suffer from major technical problems, the Steam version performs much better. Steam players will soon have more Sam on their plate with the impending arrival of Serious Sam: Siberian Mayhem, a standalone expansion. Siberian Mayhem is due out on PC on January 25 and will support 4-player online co-op.

Siberian Mayhem comes from developers Timelock Studio and original series creator Croteam. Timelock Studio, probably named after the Time-Lock machine from Serious Sam 3, is a Russian modding team that formed in 2021. As such, this standalone expansion started its life as a mod. Croteam took notice and helped the mod evolve into a full release.

Siberian Mayhem is a “lost adventure” of the hero, “Serious” Sam Stone. It takes place in Russia and will feature frozen coastlines, forests, abandoned villages, and a ghost town. New enemies and bosses, new weapons like the crossbow, and new vehicles like the snowmobile (plus Serious Sam 4’s giant mechs) will populate the five-level adventure. The new scenery shown in the trailer certainly looks like a cool change of pace for Sam, who spent part of his last game in volcanic environments.

Serious Sam: Siberian Mayhem launches on Tuesday, January 25. Preorder it now for $17.99 on Steam. Hopefully, a console version will follow sometime in the future. The original game, Serious Sam 4, sells for $39.99 on Xbox Series S|X, PlayStation 5, and Steam. It’s also available on Xbox Game Pass.
