MAP30: Icon of Sin (Doom II)

MAP30: Icon of Sin is the thirtieth and final map of Doom II. It was designed by Sandy Petersen and uses the music track "Opening To Hell".

Walkthrough
Pick up the weapons and powerups and go through the teleporter. You will find yourself on some large "steps". Each step acts as an elevator which can be activated by pressing on the Demon face on its side. Get to the top step and press the button. A small platform in the blood pool at the bottom of the steps will rise up.

When the platform has finished raising, press on its side. The platform will lower down to the floor (an elevator). Stand on the platform and select the rocket launcher. Turn to face the large Demon face wall. The platform will raise; slightly before the elevator reaches the top, launch a rocket toward the exposed brain. If timed correctly, the rocket will enter the brain and an echoing pain sound will be heard. This takes practice to time correctly. Several direct hits are neccessary to defeat the Demon. When defeated, the Demon face will explode and the level will exit.
