The Last Lieutenant:
The Soul Reaver developers claimed that they did not have enough time to implement every section of the game. Apparently Raziel's last brother, Turel, was left out of the game.

Use of the Constrict ability:
First, you must have a circular area around the target. For example: Assume that the target is a Dumahim vampire (the most common in Nosgoth). Now, without using autoface, run a complete circle around the vampire until Raziel is followed by a trace of blue energy. This energy, once fully invoked, will "constrict" the vampire, causing it to be momentarily stunned -- and allowing ample time for you to finish the it off. The Constrict ability has odd effects on humans. They are as follows:

1. Certain humans, once you begin the Constrict ability, will act as though they plummeted into water. If you do not finish the ability, they will "drown".

2. The human will get stunned when Constrict is half finished, allowing you to stop and feed on their soul.

3. The most common and normal result is that the human will instantaneously die.

The Constrict ability is required to complete the puzzle in the Chrono-chamber. Also, make sure to return to areas of Nosgoth you have already visited prior to gaining that ability. You will find that Constrict can be used on many things, and may open up useful secrets (such as Eldritch artifacts, Glyphs, and life force pieces). Constrict does not work on Kain and will not work underwater.

Do not attack humans:
You will encounter your first human in Malchia's domain. He is a vampire hunter garbed in silver armor, shoots silver stakes from a bow, and will be hostile. Leave him alone and continue on to fight the zombie-like vampire. Leave after killing it, and do not go back to the human. The next human you encounter, located in the gear room, should fall to his knees and hold out his arms. The humans now consider you an avenging angel. Do not attack them, or they will turn on you. Warning: Vampire Worshippers are garbed in red and gold. They wield throwing knives and staffs and will always attack. You may kill them as they are evil. Be sure to check your human targets. You will now be able to peacefully roam through the human stronghold.

Fun with humans:
For those of you who feel the need to unleash your wrath upon your unsuspecting human friends, go ahead and kill them with glyphs. The other humans will not acknowledge that you are responsible. Try the force, stone, and fire glyphs. You can do fun things like sailing a worshipping human against the wall, killing him, and watching as he proceeds to slide into the water only to die again.

Defeating Malchia:
To defeat the Malchia, lure him under one of the two spike gates and release them right when he is slithering under it. Repeat this on the other side of the room. After that, lure him into the center cage, quickly jump out, run to where Malchia started from, and roll the lever. This will cause the large spikes on the ceiling to come grinding down on top of him.

Defeating Dumah:
Pull the three stakes out of him to bring him back to life. Lure him into the furnace room very slowly -- if you move too fast, he will return to his room and you will have to begin again. Turn on the gas and hit the switch after he is in the furnace room to fry him.

Defeating Zephon:
Bring a torch with you to the fight with Zephon. Run up to his belly, and swipe the torch at the hole for a bit of damage. He will attack with his leg, and get it stuck in his belly. Strike the leg. He will be heavily damaged. Strike the egg hole to cause more damage. Any time he gets a leg stuck in the ground, hit it with the torch, then hit his egg sack to quickly kill him. This is easier than the "correct" method. After defeating him, you will gain the ability to scale walls.

Defeating Rahab:
You must enter the chamber in the spectral realm. Go to the top pillar where the portal is located and materialize. After a brief exchange of words, your only task is to shoot out the windows lining the room to let in the sunlight. Use the force blast-- you do not need Soul Reaver, so do not worry about taking hits. After he dies, you will acquire the swimming ability.

Defeating Kain (first time):
Simply wait for him to materialize and hit him. He will appear behind you 90% of the time. You will acquire Soul Reaver after he is defeated.

Defeating Kain (final time):
Wait for him to materialize and hit him. You need soul reaver to do damage. The spirit forge in the center of the arena always automatically fills your health. Simply run over to it to accomplish this. When you strike him the first time, he appears on the second tier, again usually behind you. Finally, when you hit him on the second tier, he will materialize on the third and highest tier, again usually behind you. Quickly hit him a third time to defeat him.
