MAP31: Pharaoh (TNT: Evilution)

MAP31: Pharaoh is the first secret map of TNT: Evilution and can be accessed via MAP15. It was designed by Dario Casali and uses a music track also played on the intermission screen.

Walkthrough
The original version of this map has a critical flaw: there is no yellow key in single player, as the key was accidentally flagged as multiplayer-only. TeamTNT released a PWAD that contains a new version of the map that fixes this issue. This can be found on their website. This patch also fixes a couple of other issues with the map, notably in the nodes.

The unofficial Doom Patcher utility (Doomgate patching utility) can also fix this issue by modifying the IWAD itself. Though it doesn't include the other fixes the official Team TNT patch does and may render your IWAD incompatible with the original version as it modifies the IWAD itself.

Skilled players have also found a couple of interesting, albeit challenging, ways to complete the level without the yellow key, involving hitting the switch on the right throne from its edge above, or wedging the player through the key-color bars in the same room to hit the switches therein.

A walkthrough without the yellow key is available on YouTube.

Secrets

 * 1) The platform with the three wooden "enemy boxes" with Hell Knights in them (in the area at the east of the map with the circular pool of water with a soul sphere in it, accessed by opening the teleporter located in the starting area by pressing the yellow switch in the "throne room") counts as a secret, even though it's necessary to access it to complete the level.
 * 2) A bit past secret #1 is a switch that opens a door at the north end end of the large area with the circular water pool. Behind this door is a very long hallway, with a red torch at the end of the first stretch. Once you reach the torch, it looks like you can only go left, but instead go through the fake wall to the right to get to an area with a combat armor vest overlooking a courtyard.
 * 3) (Secret Exit) At the end of the level you will arrive at a large lake with a dock-like structure stretching out into it, with the exit visible off in the southwest corner. There is also a shed-like building at the north end of the lake; go into this instead. Once inside, open the back wall to reveal the switch to exit to the secret level, MAP32: Caribbean.
