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 eighteen large deathclaws that patrol this map (nine to the North in three clusters, nine to the South also in three clusters) along with a special, friendly NPC named Riddick who walks East. 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.
