This is one of the best games i have ever played in my life, this is on par with valiant hearts. If you want a game that will be visually amazing and with incredible music, and as a plus it will hit you in the feels.
Just get the game like just buy it already stop waiting buy it try it live it.

Alright i don't really know where to begin here. i completed the whole game in 5.3 hours acording to steam, so let's go through my experience with the game.

First of all to me the combat felt really good, the wepons had weight to them and the sound design for the guns reflect the weight, all the animations for them was very nice. dashing and evading enemy attacks was easy enough and felt really smooth when doing it
Just as a footnote since i'm by no means an expert on graphics or stuff like it i must say that the game overall hold a very high quality in this regard

Secondly the level design was nice and well thought through (maybe a bit too linear for my taste but oh well) and the devs was really generous with the amount of combo boosters and damage boosters around the maps.

Thirdly the sound track. well the game features almost all of my favorite metal artists and the music each of them got is a blend between their own music style the games which complements the two parts perfectly. To me this game has one of the best soundtracks that i have ever heard though i am biased towards it since i am a metalhead

So overall this is a very high quality game with great gunplay and awesome soundtrack, so now maybe you would like to ask well is there anything wrong with it? well let me answer that question

The boss design are very lazy, it's the same boss through all the levels but with a different head except for the last one wich was a really cool boss fight in my eyes.

narratively the game is a bit lacking, there could have been a lot more of worldbuilding and lore to really get a good grip on what the story is about, the only explenation you really get is that the main character got her voice stolen by the red judge (aka the devil) this is in broad strockes what the narrative is to avoid to many spoilers. when the game is completed and you expect to get your voice back it really ends on a clifhanger, since ofc it wouldn't be that simple, you only got part of your voice and the other part is in heaven. I found this a bit strange since they could have started the narrative with that instead of waiting to the end of the game to tell the player, that only led to confusion for me at least though i get what why they did it if they are planing a second game that is but it felt like lazy writing, there really was a good chance in the beginning to get the player completly drawn into the story if they had given the player the whole picture on why you actually do all the thing in hell that you do, they should also have fleshed out the profecy of the Hellsinger way more since it is you. I would have loved to know more about it to fully understand what the main character is and what her purpous is.

Take the doom games for example you know what you are, you are the doomslayer and hell itself is afraid of you because you have the power of a god, you are an imortal warrior that is fuled by your hate for hell and all the demons within and you have been waging an unending war until you where captured you waited millenia until one day your cage was broken and your war started again.

the last thing i have to say about Metalhellsinger is that the game is short, unbelivebly short, the game is priced at 29.99 euro and i suspect i know why the game is so expensive even thoguh it's only 5 hours long. I do suspect that the price that has been decided is beacuse of the artist they hired, these are heavyhitters in the music industry (when it comes to metal at least) so in a sense i guess you pay more for the music than for the game itself.

so what is my final verdict. Well i do recommend the game but that's also because of my biase, as a metal head it feels like i have a game that is made speciffically for me. but for all of the other humans on this world that isn't interested in the music itself but the gameplay, well like i said in the beggining of this review the game runs like a dream with very satisfying gameplay and nice graphics together with a well thought through level design. Though since it is such a short game i would wait for a sale. i payed full price for it and feel a bit cheated to be honest since i expected more content but i do like it. hope this rant helps.
