One of the most influential games of all time no doubt and the soundtrack is just a banger but playing it on the higher difficulties most enemies are damage sponges and if you start some maps without saving (especially starting episode 2 on higher difficulties) it becomes very frustating to kill all enemies because ammo is barely enough so most of the time you are looking for ammo instead of killing demons (I repeat, this is if you start the map with 0 ammo).
