Metal Hell singer is a fun game. You are basically in hell taking out enemies and you are doing it while on beat with the music.
You get a skull, a sword and a gun to help you keep on beat and take out the enemies. The beat of the song goes along with the slashing of enemies so you determine what you want to use.
I love the skull, it shoots fire and is kind of simpler to use. If you happen to fail, you can use your score points to be resurrected up to three times. If you fail you will have to restart all over.
There are special thing you can do like if you right click you get lightning that just falls on the enemies and takes heavy damages from them and then there are black crystals with fire like on it that are floating around and if you shoot them, it will blow up causing damage also.
There are also green crystals around the map and that is for health but if you weaken down the enemies enough you can hit E on beat when it tells you too and it will take out the enemy and give you part of your health back.
This game is fun and is on the Xbox game pass that is where I have been playing it.
