For the shooter Serious Sam: Siberian Mayhem, the 1.03 update was released, which adds a huge amount of new content to the game. Bags and balance, of course, were also corrected.

The survival regime has been added with six new cards and music tracks, which can be held both alone and in the company of friends. The lineup for the protagonist was replenished with a serious Sammy, dark Delaila, biker Blaise, clergy Kurt, Dude Devolver, Oleg Oleg, Apocalypse Beast and the classic serious Sam from The First Encounter. Fans of various kinds of additional content related to the development of the game will be awaited by a pleasant surprise in the form of a digital artbook.
