Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Essentials

 * 1) In the starting area take a little walk around to grab ammo, especially rockets. A pillar at the west has a bit different colour in comparison to others. Go to the western portion and lower this pillar. Kill the revenant that hides inside, enter the teleporter.
 * 2) Kill all the disturbing monsters. Notice that each Icon of Sin wall has an opening in the form of a cage. Four mancubi hide behind this cages, kill them. Once they are killed the walls will begin lowering at each corner of the room. Grab the red key at the north-western corner, then leave through the south-eastern one.
 * 3) In the starting area go to the very north-western "house". Press the switch to enter. Inside press the switch and leave. This button opened the bars in the south-western alcove of castle (in the outside area). Visit this alcove and grab the megaarmor. The staircase will be built up. Walk up and open the door. Enter the alcove with an arrow pointing that you should jump down. Do that to lower the platform with blue key. Grab the key.
 * 4) Leave the mausoleum through the south-eastern alcove. In the outside re-enter the castle through the western blue door accompanied by two firesticks between.
 * 5) Kill the barons and lower and use a lift in the middle. You are in the western cage, and now the icon of sin will begin it's attacks. It is in the eastern cage. Shoot from the western to the eastern cage to kill the spectres that are in the same room with the Final boss. Once the spectres are dead the icon of sin can be killed.

Secrets

 * 1) When you enter the blue key door at the west open the northern wall in the next room. Take the box of rockets (sector 187).
 * 2) In the same room open the wall at the opposite site. Take a single cell charge (sector 188).
 * 3) The secret#2 is counted twice when you enter it because of the small lamp in the ceiling (sector 190).
 * 4) The secret#1 is counted twice when you enter it because of the small lamp in the ceiling (sector 191).
 * 5) Rise to the highest tower in the level by walking upstairs that are built up. Step towards the room with the arrow a bit to cross the line. This will make the platform border at the north-western house go up and down (if you just cross the line towards the alcove with the revenant there is no any effect). Head to that north-western structure. Use the narrow border when it is down. When it rises jump over into the northern window. Take the stimpack if needed and open the wall to the west. Take the invulnerability (sector 203).
