doom is an alternative type of FPS for those who sick of all the ww2 and other stuff based on real life events. Also some of us hate games where you die so quickly, one or two shots bam you dead.
However the movement seems odd in this, moving around is way too fast like a turbo speed, compare to doom original game where so much better, not enough bobbing up and down also so it feels like floating (problem many modern FPS have) and viewpoint too close to ground (am I a dwarf?)
Thankfully they did add a option to hold the weapon in middle of screen tho which is how it should be, another thing I find odd about modern FPS is the diagonal angle of weapons.
