This is a far cry of what Serious Sam stood for in the early days of the franchise. This is no longer a game where you need to carefully position yourself in between the enemies and choose the right weapon for the situation. Instead you just shoot at hordes of enemies coming mostly out of the same direction with the strongest weapon you have in your arsenal. In the second half of the game (which you reach after just 2 hours...) you gain weapons that simply outclass every weapon you have collected before. Many weapons are simply obsolete towards the end of the game. Story wise this is a pile of garbage. No one ever played a Serious Sam game for the story or its characters, but these developers thought it would be a great addition to introduce audio logs and written pages to the franchise... like who wanted that ? The characters Sam encounters during this 4-5 hour adventure are not memorable at all, even though the games cut-scenes want to tell you the opposite. I really hope Croteam takes back control of this franchise and gets back to the roots with it, but they really need to improve or change their engine as it is a hot mess in its current state. I can not really recommend the game to anyone except those that want to make fun of it in coop.

This is my first Serious Sam game (or expansion), I would describe it like if you took a game developer from the 90s who just played DOOM for the first time and let them create a game without technical restrictions. Instead of small levels with 20 enemies at a time you have massive open levels with 200 enemies coming at you. The shooting gameplay is very old-school and the story and characters similarly so, it's a total cheese-fest but I like it.

It's pretty fun for the most part, I only found certain sections near the end to be a bit annoying but overall if you like boomer shooters and have a strong PC then this is a great choice. Admittedly the performance wasn't perfect even on my 7800X3D which was a shame but it held up much better than my 5600X with which Serious Sam 4 was essentially unplayable.
