AntAgonizer's Lair

The AntAgonizer's lair is the hideout of the AntAgonizer in the Capital Wasteland, just northwest of Canterbury Commons.

Entrance
After arriving near the exterior, there are two ways to proceed. The first is through the rather obvious door, which leads to Canterbury tunnels, and not the AntAgonizer's lair; in the last room, there is a switch to open up to a stairway leading to the lair. The caverns are mostly empty but contain a few ants to fight and a decent number of frag mines. Following the caverns through to the end leads to the front of the AntAgonizer's lair.

Alternately, on the top of the hill that the door is embedded in is a grate that leads directly into the back of the AntAgonizer's lair. However, the grate is locked and requires a Lockpick skill of 50 to pick. A key exists, but only on the AntAgonizer's person.

Canterbury tunnels
Traveling through the tunnels rather than lockpicking directly into the AntAgonizer's lair reveals a relatively empty set of tunnels filled with mines, a few ants, and the occasional trap.

AntAgonizer's lair

 * The AntAgonizer can be found here sitting on her throne. Walking up to her automatically triggers a verbal confrontation with her.
 * Among the jagged rocks on the hill above the door to the Canterbury tunnels, there is a triangular section of indented land between the trail and one of the boulders. The area is noticeable as having a discreetly blurrier texture than the rest of the pathway. Avoid falling into this indentation, as its geometry will effectively render the player character unable to walk or jump, forcing a reload. As such, it is advisable to save before approaching the AntAgonizer's lair.

Notable loot
The following items are located within Canterbury tunnels:
 * A Stealth Boy about halfway down in a dead-end area. There are mines in the area, and it's on a shelf with metal boxes, immediately before the orange cones.
 * A Nuka-Cola Quantum next to the AntAgonizer's throne in her lair.
 * The unique armor known as the AntAgonizer's costume and its matching helmet worn by the AntAgonizer.
 * The unique knife, Ant's Sting, which is presented as a reward by the AntAgonizer for defeating the Mechanist (or just giving his costume, which can be reverse-pickpocketed).

Appearances
The AntAgonizer's lair appears only in Fallout 3.

Bugs

 * The dialogue options to cause the AntAgonizer to give up her costume may not appear in the list of choices when speaking to AntAgonizer. This will result in the player having no choice but to kill her.
 * There is a certain point on top of a rock which somehow considers the player to be under irradiated water.
