Could someone please give me a list of locations of where the dungeons are located at. I can't seem to find any of them. Do you have to do something special to get into them

There's a dungeon near the shipyard on oxbay. And in Redmond there's a dungeon somewhere around the church

I have just posted a link to the world map for this game which shows all the islands (see 'map' thread) on most islands there is at least one cross - i believe these are the positions of the dungeons entrances.(i could be wrong of course!)

For example on Oxbay there are 3 entrances and 3 crosses:
One entrance is in Oxbay town, go to the ship yard turn your back on it and see the door on the wall of the building opposite - its down a few steps - thats the entrance.

The second entrance is found via the beach. stand on the beach of the port (where you first arrive) turn around so your back is facing the gates to Oxbay and you are facing the sea. Walk into the water to your right and keep walking, keeping right all the time. You will swim a little. Keep going right, follow the rocks around to a little sea cove and head for a dark area on the rock until the padlock sign shows - this is the entrance.

The third entrance is a bit trickier to find. Get the best sword you can afford and be prepared to fight. Go out of Oxbay by the back door (the one leading to the outskirts not the port) go forward until you reach a fork in the road, turn left. keep going forward until the next screen loads, then keep to the right. Follow the wall until you come to the cave entrance.

Always save before entering a dungeon area as you never know what you might find.
