Underearth

The Wizard’s Manse doesn’t hold any big surprises; it follows a pretty linear path from start to finish. The one confusing area may be the large pool dominating the two opening regions. There’s ammo and health to be found beneath the surface - but it only really serves as a minor stumbling block for those unlucky enough to be knocked into the water by one of the numerous monsters populating the Manse’s narrow walkways.

Grab the biosuit and dive into the toxic moat to avoid taking unnecessary damage

What the Manse does have to offer is the thunderbolt, a new weapon that shoots an extremely powerful beam of electricity. The thunderbolt should be used sparingly, however, because ammo is in short supply, and the weapon is much harder to aim than others. Players depending on Quake’s auto-aiming feature will be disappointed by the thunderbolt’s inability to automatically hit foes on other planes. On the other hand, those who take time to learn to aim well will have an extremely effective implement of destruction at their disposal. An additional note: Unless you have a Pentagram of Protection, you should never use the thunderbolt underwater, for obvious reasons.

Secret Area 1
On the opening bridge, drop into water and swim around the round column dominating the center of the pool. You'll see arrows on the base pointing to an elevator, which will take you up the column to a box of shells.

Make sure you have plenty of health before pressing this button - you'll be spending the next few minutes underwater

When you reach the room with the toxic pool and the thunderbolt, a variety of monsters will begin attacking you from all sides. Grab the biosuit and jump in the toxic pool on the other side. Head right into the alcove with the elevator. This way the resident monsters will take some damage from each other before you have to deal with them. After you are back in the room, jump to the central platform and turn around. You’ll see a 100 health kit sticking out of the pool.

To get out of the room, shoot the button on the left wall over the large pool. This will activate a moving platform. Jump on the platform and shoot the button on the right wall. This will release a stationary platform, which you can jump onto. On the far wall you will see some dark blocks. As you approach, the bottom block will move out of the wall. Jumping onto it will cause the next step to extend. Continue up until you reach the top.

In the top room of the Manse, you’ll find a star button at what seems like a dead end. This button actually activates a caged elevator, which will take you through an underwater passage to the next area of the level. Before pressing the button, make sure you are stocked up on health - you'll begin to drown before the cage reaches its destination. If you need to return to this area of the castle for any reason, there is a simple method. There is a small pool in the room where the cage ride ends. Jump in this pool and follow the hallway to the end. Hit the wall to open a doorway.

On the pathway to the gold key, you'll pass this wall. Note the different texture on the center panel - it's the doorway to Secret Area 2

Secret Area 2
After you get the gold key, walk back down the hall, turn the corner, and look at the central panel in the wall to your right. Hit the area where the texture is slightly different to reveal a red armor.

There are numerous monsters behind the gold door. Letting them fight each other is particularly effective. Open the gold door, then run back into the water. The monsters will make short work of each other, leaving only stragglers for you to deal with.
