A technological masterpiece when it came out and still boasting a very distinct graphical style. The tone of the game shifted a lot compared to the previous games though. While DOOM always had horror elements to it the focus on dark hallways, jump scares and "cheap tricks" didn't work for me that well.
Add to that some gameplay problems like not being able to hold a flashlight and a weapon at the same time and enemys always spawning in right behind you.
Not the best DOOM game, but interesting enough and still very playable.
