Run up the hill ahead, hugging the right-hand wall. Enter the castle gates and then the open door on your left. Hug the left wall and duck through an opening to avoid two Krall, and enter the Great Hall.

There's a blue carpeted hall below - open the chests to find some goodies. Find the four bookcases to the right of the fireplace. Find the protruding blue book and push it to open a secret entrance. Kill the Krall and grab the Super Health, then take the hallway to the right of the bookcases.

Turn left and make your way into the Chapel. Read the book on the podium, leave the Chapel, turn left and hug the left wall, heading outside. Take the downward sloping passage and the descending stairs.

Open the doors at the bottom, and take the lift up. Kill the sleeping Skaarj, take the assault armour and ride the next lift up. Turn left, go up the stairs and you'll be back on the landing near the Chapel. Cross the double stairwell and turn right through the entrance ahead.

Walk up the ramp in the entry hall and turn left at the top. Follow the corridor, search the bedrooms in the hall above and then step onto the balcony to find the bell tower containing an assault vest.

Return to the Bedroom Hallway and enter the inner courtyard door. Walk up the ramp and enter the tower. Kill the Skaarj gunner before he nobbles the Nali, and follow the four-armed freak to a secret area containing a Super Health.
