Doom II: Hell on Earth/MAP11: 'O' of Destruction!

Shortcuts

• You can unlock the exit without obtaining the red key. To do so, head to the north of the circle - you should see a window in the north west area that is just next to the outcropping wall. A switch should be visible from this window. Jump into the nukage pit, and get as close to the switch as possible. Press the switch to unblock the exit.
