Wolfenstein 3D Cheats
The secret rooms are like any other room except they are accessed by a "secret passage" (not really a door). There are certain wall panels which can be pushed. The wall will then slide back revealing a passage to another room. Secret rooms are usually used to store treasure, keys, food, first aid and ammo packs and more powerful guns.
The secret levels are just another level which has been made harder to find than others. To get to a secret level a special elevator (in appearance they look like a normal elevator) must be taken from one of the normal (non-secret levels). Special elevators are hidden. There is one secret level per episode. After a secret level is completed, the exit elevator will provide to the next normal level to be completed.
