Barely recommended. It's the weakest of all main Serious Sam games without a doubt (below Next encounter and 2), some maps are insanely huge but there are baarely any encounters, and the ones there are, are usually lackluster and even boring. (and i played on Serious difficulty throught all of it and all secondary objectives)

There are only a few good/brilliant fights, the standout being the one in a Quarry... However, having slogged through the rest of the game to get there, and afterwards having mediocre to some good fights sprinkled throught... doesn't fully redeem it in my eyes. I am sure most of the space could've been used better (as exemplified with the quarry fight)

This is before even going into it's other problems like:
1) Having bad performance while looking just a tiny bit better than Sam 3, i had to tweak the game quite a bit to feel stable.
2) A badly paced and not so good or entertaining story (with, again, only really one/very few standout moments)
3) The latter chapters fight's with the exception of the final chapter feeling emptier/more rushed than usual
4) Some gadgets felt completely useless despite the efforts required to get some of them.
5) Some upgrades feel mandatory like the reload speed or reloading while sprinting when they could've been there by default and tuning a few fights with them in mind, and other upgrades being extremely niche/useless.

With all they got, they could've crafted many more kickass fights and a better story, but i guess being in development hell for so long made things very messy. Here's hoping the next main game comes brilliantly after all lessons learned from dev hell, and some of the experience with the Talos Principle 2.

A good game can be played several times,but no more.Why is that?But because the game is boring

I would definitely recommend this game. I think this is the funniest Serious Sam game so far, regarding to gameplay. It is just fun to play. I really appreciate the fact that Croteam still experiments with the Serious Sam franchise. It is different every time, and I love it! Actually, I think this is the reason Sam is still alive, and will be. I will accept any other differences in the future Serious Sam games, even if it is not like the classic games, which is good, I don't need the same game every time. Thank you so much, Croteam! The next station is Serious Sam 4 Siberian Mayhem.
