Compared to SS3BFE:

• less brown but often uglier despite being newer
  
• a few more weapons and enemy types
  
• witch bride and technopolyp have been fixed
  
• skill tree, weapon mods, consumable "gadgets"
  
• unfunny writing

The game doesn't feel finished but it's still fun to shoot the hordes if you can look past the game's flaws. 14 hours for all achievements

Love this game! Hell I love all the Serious Sam games!!! Well except maybe for Serious Sam 2 lol If you love nonstop shooting and action this is the game for you! Heck the entire series is for you with the exception of Serious Sam 2 that is lol Must own and play!!! Hope they make a Serious Sam 5 next!!!

After finishing SS4 it was hard for me to decide on how I was going to review this. I am a very big Serious Sam fan loving the first three games. I might as we'll get my system specs out of the way first. Right now I am running Ubuntu 24.10, AMD 5800X3D, 128 gigs of ram and AMD RX 7900 XTX. Also running the most current version of Proton (Steam).
I really love the premises on what they were going for in this game. If it was not for these issues I would fully recommend this game. The two biggest issues that I had that took myself out of the game was when the game would random crash. There was also a weird part when I beat the game and at the end it said I died and had to do the end over again. The other issue and really took me out of the game was the textures not loading right. Almost all of the cutscenes were missing textures to load at some point. Also during gameplay certain objects would not load the textures right.
Out of Serious Sam 1-4 I would go 3,2,1 and than 4, 1-3 still hold up today as solid and fun games. To bad that there was not more deveolpment on this game to fix these bugs.
