You might want to place the other masks beforehand so you'll have plenty of room in your inventory for ammo and health items. Place all four Death Masks and go to the fallen casket.

BOSS - Keep moving. The big spider will charge you if you stand still too long and it likes to spit poison. Shoot at it with the shotgun until it goes down.

Afterwards, grab the Knife and cut through the spiderwebs to exit out the other door. Use the Flamethrower next to the west door to unlock it. Run around until you see another boulder.

Head down into the Altar, making sure you have both the Medal of Wolf and Medal of Eagle on you. Run though the hall and keep going down until you reach a ladder. Go down.
BOSS - You could try and shoot it out, but conserve your ammo and do this: push all four stones off of the corners. Remember that this boss can move pretty fast and can jump. So, you might want to have it follow you to one side and then run to the other to push the stones off.

BOSS - Shoot at the boss to get his attention away from Rebecca. When the boss heads for you, shoot once or twice and then move away at a 90% angle from where the boss is approaching.

Pick it up, equip it and fire away. If you let Rebecca die earlier, you won't get have to go through this fight.
