What players are saying
Counted from the reviewers’ own thumbs up/down on the 181 English Steam reviews we collected, not by the AI. Valve’s all-language rating: Very Positive (4,875 of 5,289 positive).
Players widely consider Siberian Mayhem a significant improvement over Serious Sam 4, praising its pacing, level design, and optimization. [1][2][3] Some reviewers note the campaign is short, with a mediocre story and performance issues on certain hardware. [4][5][6] Fans of the series appreciate the old-school chaos, secrets, and new weapons, calling it one of the best entries. [7][8][9]

ur biggest enemy in this game is optimization, and the devs aren’t even bothering to fix it.

OK THIS IS WHAT SERIOUS SAM 4 SHOULD HAVE BEEN. PROS: Better optimized and more fun than SS4. You do not need Serious Sam 4 or any other game to play this. This is NOT a DLC but a stand alone game. Proper mix of enemy hordes in big areas with some fun secrets. Sadly its set in an alternate timeline between Sam leaving Siberia Oil Rig and meeting Brand & Ugh Zhan in main timeline. There are a couple of changed …

Paint The Snow Red Serious Sam: Siberian Mayhem is a stellar standalone expansion that improves on the main game in almost every way. Its mix of gloriously gory, fun, simplistic gameplay, dramatically improved pacing, and excellent level design makes this an easy recommendation especially if you enjoyed Serious Sam 4. Pros: An awesome arsenal and very snappy gunplay. Good visuals and optimisation. Great exploration …

All aboard the tra-a-a-ain, Ah-ha-ha-ha. I'm thrilled. Drive, adrenaline, jumping, running, projectiles flying from all sides and in all directions—everything you need for a game like Serious Sam. I don't know what happened, but this time the developers managed to make THE BEST Serious Sam game possible. I didn't enjoy the 3rd and 4th games, but Siberian Mayhem... just WOW. While playing, I once again felt that …

Way better than Serious Sam 4, disappointed with how SS4 turned out! One of the best FPS games and a step up from Serious Sam 3! :)

negative · AI labelView post →Ooh, (very WIP) trailer dropped for Zortch 2. The first game was short but tons of fun, like a long-lost N64 shooter given a PC remaster. The sequel kinda makes me think of Serious Sam meets Duke Nukem 64 so far.

positive · AI labelView post →It's funny that people were freaking out and declaring Serious Sam dead because a third-party spinoff game... existed. Forgetting all the other weird third-party spinoffs we've had over the years.
neutral · AI labelView post →I've thought about how I'd handle a Serious Sam video, but the games are all so similar and repetitive that I think I'd just do one giant video covering every major Sam game. What do you think?
neutral · AI labelView post →A super early version of the Colosseum from Serious Sam Next Encounter, running on the PC's Serious Editor. This is from January 25, 2002, while the game wouldn't release on GameCube until April 2004.

neutral · AI labelView post →The easiest way to dabble in #GameDev? Modding. Pick your favorite game and it probably has some sort of modding support. My first #IndieDev experience was adding a tiny feature to Serious Sam, back in 2001. It was ~5 lines of code and seeing it in-game felt amazing.
neutral · AI labelView post →People talk about video games that look fake sometimes but I think Serious Sam TSE might somehow have the fakest looking video game cover art ever.
positive · AI labelView post →Please everyone buy this game It's so great and i have been enjoying it lots too! It has catgirls. It plays similar to DOOM Quake & Serious Sam, but it's own unique experience to the FPS genre. Also a meow button And made by trans devs too 💙🏳️⚧️
neutral · AI labelView post →It's literally like SS4, it's like if the missions in Siberia were expanded. Nothing more. For the rest, it's old school violence, no brain just shoot. Is it bad? Well, depends on what you seek, it's a nice medicine if you need to switch your brain off completely for some hours. What is wrong is how taxes my PC for the poor graphics it has.. it can also be finished in like 3 hours, which is pretty short. https://steamcommunity.com/sharedfiles/filedetails/?id=3576474672

neutral · AI labelView post →Serious Sam does a better job being a "bullet hell" than alot of gentrified modern/indie games putting bullet hell elements in their game cause it actually gives a shit about you actually dodging shit and not having a million different ways to ignore damage
positive · AI labelView post →Onirism will likely always have some rough edges, because it is by a small indie team, and the game is simultaneously Serious Sam, Blood, Call of Duty Zombies, Bioshock, Timesplitters, Halo, Star Wars Battlefront and every PS2-era mascot platformer ever made.

neutral · AI labelView post →I made the mistake of playing through both Mouse PI and Serious Sam lately. Too many jumpy shooters that get me all worked up and tense. Need to play something more laid-back next time like an RPG or Kirby game.
negative · AI labelView post →On this windy #RandomGameSaturday, I have Serious Sam: Next Encounter, a game not to be confused with Serious Sam: The Second Encounter or Serious Sam II no matter how much it sounds like a direct sequel. I've not played much of any game in this series, but I feel like I'd really enjoy it once I do

neutral · AI labelView post →In some videogames with no player character options, you get to actually have a character (Serious Sam). In some, you get a blank slate with pronouns (FEAR). To an extent, I can accept it if the game is old. . . . This post is about Mechwarrior 5.
neutral · AI labelView post →Serious Sam on the original Xbox. Never played Halo on it, lmao, But Serious Sam I loved so much, I'd regularly try to convince my parents to play it with me No clue who I'd be if I hadn't played that silly little game back when I was a wee little batty
positive · AI labelView post →I found out about new Serious Sam game. Not really sure if I want to play it or not. I love Serious Sam but this game looks like the most generic "Fortnite wanna be" slop. Feels like they wanted to make Serious Sam popular among gen Z or something. I hate that trend and direction.
negative · AI labelView post →🔴 Another new Serious Sam video! This one covers the leaked game design document, sketchbook and various community projects.
neutral · AI labelView post →With a spin-off, the first question that always comes up is: Does the story take place before, between, or after the previously released games in the series? In the case of Siberian Mayhem, the answer is a bit more complicated than usual, because the story cheekily inserts itself right in the middle of Serious Sam 4: According to the developers, the events take place between the last two levels of its predecessor (Serious Sam 4). According to this, Sam is still on the hunt for General Brand…

neutral · AI labelView post →87. Serious Sam 3 Jewel of the Nile: Solid little expansion. The secret weapons from the main game became normal pick-ups and the hammer is now a sick axe. The first couple levels are oddly stingy on health though which got annoying. I liked it, but I'm taking break before I play Serious Sam 4!

I was never fond of it and every title I started began boring me after ~1 hour mark, resulting in a refund or abandonment. This changed with Siberian Mayhem. Not that long ago I seriously tried The First Encounter, which according to Steam reviews is the best title in the series. I was very disappointed. To not repeat my review on it I'll…
