Serious Sam Siberian Mayhem is just around the corner as we are less than 10 hours from its release time on Steam for PC.
Continuing its portfolio of Serious Sam over the past few years, Devovler Digital is preparing to launch a standalone expansion from the series that takes players to the frozen lands of Siberia, the place that will soon turn into hell for Sam’s enemies.

Set in the cold and snowy lands of Russia, Sam Stone will follow the traces of General Brand in the frozen lands of Siberia while having to deal with so many giants and monstrous enemies in his own way. And you know what’s his way, don’t you?
Serious Sam Siberian Mayhem Release Date and Time
Serious Sam Siberian Mayhem will be available on January 25 at 9 am PT/12 pm ET/5 pm UTC/6 pm CET. The game will only be available for PC through Steam, and it costs $19.99, though you can pre-order it now for $17.99 as there is a 10% off available until launch.
You can also grab a bundle of Serious Sam 4 and Siberian Mayhem for $48.12 at the moment.
Similar to Serious Sam 4, you will be able to play Siberian Mayhem in online co-op mode with a friend. The developers have not revealed how long it would take to complete this standalone expansion, but it seems like a big world with many mysteries awaits the players.
So, if you really enjoy chaotic first-person shooters like Doom, then the fun atmosphere of Serious Sam with so many different enemies and weapons could be a good fit for your taste.
Currently, there are no plans for bringing Siberian Mayhem on consoles.
