Quake

Hint: Well Of Wishes secret:
This is a secret extra for the Crypt Of Decay (Episode 2 Map 3). After the spiked hall, go forward, turn backwards, then look to your right. There is a room there where you must take a leap of faith to cross. Get the quad and keep going towards the wall until you reach a hall. Enter it and go down and swim. The dope fish is at this location. Go to the left of the fish and shoot to find the exit to the secret level.
