Oh man I bet you can get doom running in the scenario editor. The new devs may even be willing to enhance it somehow so that you could.
Although I have not really played or watched competitive since The Viper left for Facebook.
I did come across the competitive scene there about 2 years ago. Honestly I found it both fascinating and a bit disheartening. There was I happy with my occasional dad game where I was regularly beating the AI on one of the higher levels. Nope. Apparently still a noob after 25 years.
The speed and accuracy that they move and build at is astounding.
