Pitch Black

 is a special encounter in Fallout Tactics.

In this encounter, your group will start off in the center of the map, completely surrounded by darkness and a few pools of radiation. There are approximately one to two dozen large deathclaws that patrol this map along with a special, friendly NPC named Riddick. If you manage to make it to exit zone while keeping Riddick alive, you'll be able to recruit him later at one of the Brotherhood of Steel bunkers.
