Serious Sam: Siberian Mayhem Announced

This announcement on Steam officially announces Serious Sam: Siberian Mayhem, a new installment in the rapid-fire Serious Sam series of first-person shooters. This will be a standalone expansion to Serious Sam 4, so the original game will not be required. Devolver Digital teased this news last week, and as that tease stated, the game will arrive this month. Specifically on January 25th. This Reveal Trailer lives up to its name with a gameplay reveal. Here's more mayhem, which started as a project from a mod team:

Independent developer Timelock Studio and Serious Sam 4 developer Croteam have teamed up to unload standalone expansion Serious Sam: Siberian Mayhem into the ongoing adventures of ‘Serious’ Sam Stone. The cold winds of chaos blow onto Steam later this month when Serious Sam: Siberian Mayhem launches on Jan. 25.

Make your way through the vast Russian landscapes in five massive new missions set along Arctic coastlines, desolate forests, abandoned villages and a chilling ghost town. A new set of dangerous foes and bosses join the Horde including some of the most advanced and intimidating creatures the hallowed FPS series has ever seen. Lock and load new weapons like the experimental crossbow or jump into vehicles from snowmobiles to towering mechs.

Serious Sam: Siberian Mayhem took an unusual path, starting as an ambitious project from longtime Serious Sam community modding team Timelock Studio. It quickly evolved into a standalone expansion under the guidance of Croteam.
