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.
