Near the end of the game, you are in a tomb with infinite doors. You have to find the correct series of doors to progress. Go to the landscape view. Always start at the door with the face above it and go clockwise. The order is:
1. Fourth door from the entrance
2. Seventh door from the entrance
3. Third door from the entrance
After you have successfully done this you will be taken to the second level of this room. It is almost the same, just with more
doors. The order is:
1. Fourth door from the entrance
2. Ninth door from the entrance
3. Fifth door from the entrance
An intermission sequence will then follow. In the circular room you find in the tomb, there are doors that you must enter in the correct order, or be teleported back to the start. One way to make sure you go through the correct door is to listen carefully. When you are in front of the next door that you need to enter, you will hear the sound of trickling water. This indicates that you are standing in front of the correct door. Repeat this until you have solved the maze.
A Prisoner Seeking An Escape: Hangman
When you reach the bottom of the chamber in the A Prisoner Seeking An Escape level, kill all the sand creatures and then enter the cell to the left when looking at the save point. In the left corner of the cell is a little joke on the wall. Take a closer look in first person view at the drawings you find there. Obviously the prisoners where playing hangman here.
After getting the second sword that can break walls (approximately one third of the way through the game after the "Above the Bath's" area), you will reach a large location where you must pass through a door with Farah and activate a lever to open another door to a hallway filled with scarabs. There are three positions to this switch (open door into room, open door to hallway with scarabs, and open secret door to the classic Prince Of Persia). The switch is located at the end of the room, near the save point and near a large piece of rubble. There is a wall opposite to that lever that appears to be unbreakable, and does not look like other wall areas that can be manipulated. When you hit this secret area on the wall, it will not spark as expected. After setting the switch to unlock the door to the mini-game, keep hitting the non-sparking section of wall until it breaks. A message will appear to state that the classic Prince Of Persia has now been unlocked. Alternately, successfully complete the game.

Final Battle
When u get to the battle with the viseor, u will have to beat 3 of his "clones" before attacking the actual viseor. This will take a while because the "clones" will block almost all of ur attacks. You must block his attacks and counter attack to do any kind of damage.
Tip: Easy kill
To get rid of human sand creatures quickly, stab them with the dagger(freeze them) and then vault over them(they won't stop you) and slash them. This will save time because on the first slash they will split.
