Doom/E2M8: Tower of Babel

Press the button in the middle, get the mega armor, and head outside. On the higher difficutly levels, you will see lost souls - use the chaingun if they annoy you (if you have one). The Cyberdemon is easily killed with the plasma gun, with only 200 cells required with good accuracy and dodging skills.

Note that not using Strafe Left or Strafe Right will make the level much longer than it should.

If you only have the 50 bullets and pistol, leave the central area by the east exit to get the rocket launcher. The north exit will have many rockets available, while the west and south have a supercharge in case you get injured. It will take about 75 rockets to kill the cyberdemon.

Secrets
There are no secrets on the map.

Deatmatch
There is no changes to deathmatch, and as such, it is not a good map: There is only one rocket launcher.
