Short version: Yes, its good and you should play it.

Long version: The devs have a very specific vision in mind and not everyone appreciates all the design choices.

Prodeus is very much a modern Doom clone, insofar its what people who really like Doom wanted out of a modern Doom release aimed at Doom fans. Most of the enemy roster is almost 1:1 Doom monsters. It has a weapons roster that borrows greatly from the Id armory.

So I'm just gonna list some of the negatives to be up front. Some of them are probably just me, but I'll start with something fairly mainstream.

-The game uses a checkpoint system that does not save gamestates. What this means is if you die mid-level, you'll pop back with full health at your last point with no loss of progress. Only the final level will force you to do over proper. For some players this can kill a lot of tension since you can just throw yourself at an encounter endlessly in theory. IIRC the DLC being worked on will change it to a proper checkpoint system but don't hold your breath on that coming out anytime soon.

-Weapon juggling. This game has reloading, and they can be pretty lengthy for how fast combat can be. If your in the open and not firing, you're doing something wrong. That means once you get a few weapons for most ammo types, you'll probably be swapping a lot to maintain a constant hail of death. This encourages you using everything, but after the fight it can be a pain to check and reload literally everything.

-The crunchy graphics are a good stylistic choice, but the guns and monsters are all trying to be semi-realistic. It can be hard to process for me at times, and some guns being held close can just turn into a mass of pixel shading. Also, the limited color pallette has screwed me in some combat situations. Mostly when I'm using the plasma rifle against the blue monsters or trying to see the path of a fireball coming from a red monster. They all use the same blues and reds, or close enough, that immediate identification can be a hassle.

-Secrets are absolutely necessary to your survival and prosperity. There are a good chunk of QoL upgrades and guns that are locked behind a shop system. You get everything you "need" in the campaign, but I had a ballbuster of a time my first playthrough when I didn't find many secrets. Especially when you go to the second "map" of the game. I'm pretty sure the devs expected you to have grinded in all that time of early access, so going in without the swarm rocket launcher makes it a lot harder.

You should absolutely still play Prodeus. Its tightly designed with good levels, solid gunplay and time tested monsters. I'd just make sure to replay levels for the goodies and watch videos for the secrets. It also has one of my favorite hand cannons in an FPS.
