Ravenscar Hospital:
Now that you have arrived to find Angela, your first order of business is to add holy water to the sprinkler system. Head to the end of the lobby and a swarm of enemies will rush out from the elevators. When the final impaler breaks through the door, kill it and then head down the stairs. Make your way around the corner and face off against two inpalers. Continue around the corridor and you will come to a set of locked doors to the left. Make your way to the right and go through the door there. When you enter the red lit room, some demons will break through the door to the left. Kill them and enter the next room. Follow the same pattern here and make your way out to the hall way. Head to the right and you will come to a set of stairs.
Head up and kill the demons there and head through the door with the green light once they are dead. Go to the right and enter the office there and follow it through to find the dead security guard and grab his key. Make your way back out to the hall and continue to follow it to the set of double doors. Head through and continue to the far end and make a right. Head around the corner and you will come to the security office on the left. Enter it and use the control panel there to open the gates. Now you need to head back out and back down to the lower level. Take the same path you took to get up to the office and head through the first gate you come to. Follow it to a brown door and enter the tunnel there. Continue to the end and you will come to the boiler room. Move the block in front of the boiler and climb up to the top of it. Drop in the cross and you will need to set off the sprinklers.
Follow the door out and head down the hallway to the stairs. Head up and start to make your way through the halls. You will eventually come to a hallway with a large hole in the floor and a room to the right. Now you will start to see red boxes on the walls that will allow you to turn on the sprinklers. Pull them and the nurses will turn to their true form. Continue down the hall pulling the red panels and following the physiotherapy signs. Eventually you will come to a group of nurses and one will have a set off key on them. Kill them and take it and enter the physiotherapy room. Quickly turn to the wall and turn on the sprinklers. Kill the swarm of nurses and head for the door at the far end.
Hyrdotherapy Pool:
Now it’s time for the ending to begin. As you enter the Hydrotherapy area, grab all the ammo from around the room and head over to Angela when you are ready. Gabriel will enter the area and you will need to square off with her. Use the dragon’s Breath to do the most damage to her the quickest. Keep the demon leech shield on so you don’t take too much damage from her lightning attacks. When you nail her a few times, she will start to fly out through the windows in the ceiling and come back in. Keep on her with the flame thrower and eventually the arc angel will fall. Once she does fall, she will tell you that Mammon has taken Angela to hell.
Hop in the water and teleport to hell. Now you will be in the last battle of the game. As soon as the battle starts, grab the health around the area and then walk near Mammon and use Exorcize on Angela. When you do that, the spear of destiny will drop. Grab it and it will now be your secondary weapon and the only way to hurt Mammon. When Mammon is floating around the area, he will summon some demons to attack you. Kill them and ignore Mammon. When the demons die, Mammon will lower to the ground. Run up to him and swipe at him with the spear and you will hurt him. Pick up the spear again and keep on repeating the same pattern over and over until Mammon finally falls. Sit back and watch the ending scene and congratulate yourself on a job well done.
Congratulations!
