Hi can anyone give me some pointers how to get into the battle tower? I have defeated the bandits on the way to the entrance but once inside I cannot find a way past the boulders that block the passage.I have looked round the cells but I don't seem to have found anything that will help me. Tried the other entrance but it just tells me to find another way Grrrrrrr Great game though and I am really enjoying it steep learning curve that has made me lose hours of my life.
Did you check all the cells in the room where you got the cutscene with the undead Sassan? If you release a prisoner there he will tell you about a hidden passage in one of the other cells...
The cell is diagonally opposite the one with the prisoner, to the left IIRC of a cell with a bashed in door. Check the map, and you should be able to tell which wall is false.
In more detail
In the cell there is a button to open the false wall, on the right IIRC of two vertical wooden beams. In the next room there is another false wall, and another button on a beam, this time on the left, IIRC.
Once in the second part of the hidden storage area
you can find 2 small kegs of explosives, on a table before you reach a chest at the back of the room. One keg can be used to clear the cave-in, while the other can be used to open a small side passage shortly after there.
