MAP23: Unholy Temple (Doom 64)

Map 23: The Unholy Temple, is the third last level in Doom 64. The level is best described as eerie for it's unnerving BGM and very dark atmosphere. The sky is dark with forever burning green fire, signifying how deep you are in Hell. You start off in a small moat that surrounds the central temple that vaguely resembles a pyramid. On top, you can barely see Hell Knights and Spectres viciously wanting to chase you down. In the moat, there are several Arachnotrons that are luckily encoutered one by one. There is a teleport at the end of the moat that takes you to the "second" floor of the temple. After defeating the Spectres and Hell Knights, you climb up the temple to turn on the switch which will you go inside the temple. Inside the temple are several corpses and two Barons of Hell waiting to ambush you as soon as you step in. Continuing on there is a room with a couple of Arachnotrons also waiting to ambush you as soon as you take the mega armor.

Once you collect all three skullkeys you need to enter a room to input a code-like sequence that corresponds to the colour of a key. The reason for this is because through-out the level, there are three locked doors that have the colour of the keys etched in right beside it. Depending on the order from left-to-right is what you must enter in the code room. If you get the code wrong, you are trapped and force to fight a Hell Knight. If you get it right, the room will unlock and you must push a button that will remove one barrier from the exit, hence the reason why you must do this. Once you removed all barriers, you will be able to exit to the penultimate level No Escape.
