after punching your chief in the face cuz he wanted you to kill innocent people, he makes you go as janitor in mars moon, but then, disaster strokes, after UAC, that you work for, fails at making portals, they kinda didnt, the portal lead demons to mars!! killing everyone in the station, your goal is to reach the heart of the invasion and kill all demons in your way, have no mercy, rip and tear, cuz that is what they are gonna do the moment they see you, but after tricking you, they do actually kill you, leading you to hell, where you kill the spider master mind behind the invasion, and saving mars... but not earth, but that a story for a different game.
hell yeah, doom, i love this game, it has simple machanics, no over the top stuff, no dash, parry, the closest being just running, this game allways had mouse support from the start in case you didnt knew, but people were to excited to play that they didnt checked the options properly and just when full keyboard + the fact playing using mouse wasnt a standart yet, so people werent fully aware of it as an option and how great it could be, its fun, and short if you know what youre doing, it lacks the fun new monsters of doom 2, bit have a more coherent map design, everything works flawlessly, and the music? unforggetable, this is easily one of my favorite games out there, 10/10.
