This game and level brings back some flashbacks. I'm sure I remember it from when I was younger. I remember playing it in the dark on a computer with alright speakers. Then later on I played Doom 64, beat that game. I am playing an Xbox version from the Doom 3 release.
The level Dis has some lore. It is based on the city comprising the lower circles of Hell in Dante's Inferno. Dis is also an ancient god of the underworld. This level is also known as the worst Doom level or least favourite based on the simplicity of the level compared to the rest of the levels of the Inferno segment of the game.
I personally always enjoyed this level. It's a free for all I thought. Would be fun to reach this level on a harder difficulty to make it a bit more challenging
I recorded it on my phone, took just over a minute to complete
