Kill the rat god

Kill the rat god is a side quest in Fallout 2.

Detailed walkthrough
There is a big problem in Trapper Town, the west end of Klamath. Slim tells the Chosen One he thinks there is something in the caverns below controlling the rats that have been infesting the place.

The key to the warrens door can be obtained in one of several ways, including:
 * Convincing Slim to give it away.
 * Steal the key from him.
 * Lockpick the door.
 * Sleeping with Slim (Females only).
 * Looting him of it.
 * Feeding the dog near Klamath's town center a piece of meat jerky (he will cough a key up and follow the Chosen One around).
 * Bartering for the key (it has a value of 0, so he will accept anything offered.)

Once in the warrens, the Chosen One must battle their way down through the caves until they reach the second sub-floor. Below lies Keeng Ra'at the rat god, the brains behind the invasion. The giant rat has a considerable amount of HP, and will be challenging. If it gets a Critical Hit in the eyes, no matter the damage - it will always be fatal.

Rewards

 * 300 XP
 * +50 Karma

Behind the scenes
When the quest is completed and the Chosen One talks to Slim afterwards, he will state how they are a regular "Pied Piper". In accordance to the goal of this quest, the 'Pied Piper' is a mythical character said to have removed an infestation of rats from the town of Hamelin during the Middle Ages.
