In the room with the pit, descend the staircase and look in the nook to the right. The switch is next to some candles. Drop into the pit to find the Classic Map entrance.
Map Strategy
Tower of Babel starts out in a small room with three doors and switches. Activating them reveals steps in front of each door. Enter each one and grab the resources and then proceed outside to face the Cyberdemon. Light it up with the Rocket Launcher as you strafe to avoid its own rockets. Watch out when close as it swipes with a scythe. Defeat the beast to complete the mission.
