Serious Sam: Siberian Mayhem is a stand-alone expansion to Serious Sam 4, working just as well whether you’ve played SS4. Siberian Mayhem cranks the action up to 11. It’s a hybrid experience ready to deliver explosive fun to fans of classics and the latest instalments to the series.

Siberian Mayhem is very important in another way. This game was designed, and its development has been led by some of the most talented members of the Serious Sam modding community, joined together under the banner of Timelock Studio. The team consists of well-respected names, including DedKadath, Asdolg, YaNexus, UrbanDeHuman, FreekNik, MintFritter, NSKuber, and Ar2R-devil-PiNKy, who worked closely together with Croteam to deliver absolute Mayhem. Here is a message of appreciation from the Timelock Studio team for the Serious Sam fan base:

To experience the “Mayhem” yourself, head over to Steam store page:

We are happy to inform you that Serious Sam 4 has blasted its way to PlayStation 5 and Xbox Series X/S!

The scale of chaos has reached unprecedented levels! The classic Serious Sam formula is revamped by putting an unstoppable arsenal up against an incredible number of enemies that requires players to circle-strafe and backpedal-blast their way out of impossible situations.

The iconic cast of alien invaders returns with some new reinforcements! Fight through unbelievable numbers of Mental’s minions, including the iconic Headless Kamikaze, Beheaded Rocketeer, Kleer, Scrapjack, Werebull, and Khnum! Square off against brand new enemies and towering monsters like the frantic Processed, repulsive Belcher, the hard-hitting Zealot, and more.

The time has come to release another one of our co-production babies into the wild. This time, the world will be taken by a storm named The Hand of Merlin.

Made by some of the standout Croteam veterans who worked on The Talos Principle, and written by Jonas and Verena Kyratzes, The Hand of Merlin blends Arthurian legend with sci-fi horror. The game is a tactical masterpiece if we do say so myself, but don’t trust our word on it, check it out for yourself as it’s available in Steam Early Access now.

Make sure to provide any feedback directly to Room-C Games. They are a passionate and super talented bunch, eager to hear what everyone has to say. Find them on the official Hand of Merlin Discord server.

The Serious Sam series celebrated 20 years of shooting action this past Sunday, March 21, and we wanted to make this milestone special by delivering a huge update to not one, but two of our games.

First up, Serious Sam 4 got the long-awaited 1.08 update which includes a bunch of brand new playable characters, even more fixes and tweaks, as well as official modding tool in Serious Editor 2021, powered by Serious Engine. The modding tools are closely followed by full Steam Workshop support, and we’re extremely happy to see that our amazing community is already hard at work, creating magic in Serious Sam 4.

You can find much more info on this latest Serious Sam 4 update in our official announcement on Steam.

The second updated game is much more unexpected. Many, many years after it was touched last, we have updated Serious Sam 2. As part of this update, Serious Sam 2 got 12 brand new multiplayer maps, and some incredible gameplay improvements including dual-wielding, sprinting, and much more. Find out everything there is to know about how this update came to be, and what it includes, on the Steam Community Hub.

To continue our celebrations with you, the fans, we have discounted the entire Serious Sam franchise on Steam, and cut the prices down by up to 90%. Check out those amazing deals on the Serious Sam Anniversary Sale page on Steam.

As promised a few weeks ago, Serious Sam 4 Update 1.07 arrives just in time for the Steam Winter Sale and comes with a bang. If you haven’t guessed by the cover image, the update celebrates upcoming Holidays with a special time-limited in-game event and a new playable character. That’s right, Serious Sam 4 is taking you on a trip to an alien-infested Winter Wonderland.

To activate this special event, make sure you are playing on Steam, then find a lonely Christmas tree on “Death from Above” and slap some decorations on that bad boy. Do it as Santa Sam for a complete experience.

Alongside the new Christmas event, Serious Sam 4 Update 1.07 delivers the long-awaited Survival mode. Jump in solo or with friends and see how long you can survive fighting ever-growing hordes of aliens across three very different locations.

This update also contains various fixes and tweaks, so make sure to read through the entire changelog on Steam or Reddit.

During the Steam Winter Sale, Serious Sam 4 is available at 20% off, so grab it now if you haven’t already.

As always, we’ll be looking out for your feedback and acting on it. Feel free to report any issues in the tech-support subforum, and we’re always open to suggestions via forums. We’ll love you even more if you join our official Discord server.
