Pharos, Temple Of Isis

Pharos Temple of Isis is the 19th level in TR4. It has no secrets. The main goal is to get 4 black beetles and get the winding key. To do that you must slide down and get 3 black beetles with the crowbar and get the 4th one from the next level. Then you must return to this level and place the 4 beetles in the pyramid. Then you must collect both parts of the key and combine it so you can progress in the next level.
