The Hole ( The Pitt ) The Hole ( or the Arena ) is an area where arena style fights occasionally take place at Ishmael Ashur ' s whim . Slaves fight against other slave combatants in the " Fallout 3 " add - on " The Pitt " . The Lone Wanderer enters the Hole after starting the second half of the quest Unsafe Working Conditions . The fights are organized into three rounds where the Wanderer must battle against three slaves , then two gladiators and finally defeat the Hole ' s champion , Gruber . As soon as a fight begins , radioactive barrels are dropped into the arena . They act as obstacles , but more importantly , give off high amounts of radiation . The entrant must defeat his or her opponents and exit the arena before dying of radiation poisoning . Background . Lord Ashur used the arena to build his army of Pitt raiders by weeding out the infirm or incompetent . Rules . The rules are simple : the contestant is allowed to bring any weapons and items they have for the fight , and may not leave until defeating the opposing combatants or dying of radiation poisoning . Faydra tells them that they may take whatever they want from a nearby locker . The items are very low - end : a low - caliber pistol and some common Melee Weapons . At the end of each fight , Faydra will cleanse the entrant of all of his or her radiation . Note that she will not heal them ; the entrant must find another way to mend their injuries . However , there is a convenient water fountain next to Faydra that can be used to restore vitality . Although the fountain is irradiated , the radiation from the water is insignificant compared to the high radiation levels received from fighting in The Hole itself . Also , this fountain only gives one rad after fights . Once the entrant is done fighting in the arena , the fountain will give 3 rads . These are not honorable fights : the entrant may loot bodies as he or she pleases . After completing the fights , they are freed from their " slavery " , and can grab their equipment from a footlocker outside The Hole . The Rounds . Round One . The challenger faces two to three unnamed slaves armed with a variety of weapons . Generally , one slave will have a combat shotgun , which can be deadly to a character who has not got much in the way of armor . The other slave or slaves normally have Chinese assault rifles . Round Two . The challenger must fight the Bear Brothers , Grudd and John Bear . The Bear Brothers ' armor is in exceptionally good condition ( more than 90 % ) , giving them significantly better than normal protection . Round Three . The final round has the challenger fight against Gruber . He has Gamma shield armor and a metal helmet , as well as an Infiltrator . He has a large amount of HP ; combined with his heavy armor , this allows him to take quite a lot of punishment before dying . Like the Bear Brothers , Gruber ' s armor is in exceptionally good condition ( more than 90 % ) , giving him significantly better than normal protection . The armor - piercing deathclaw gauntlet recently acquired from the Bear Brothers can be extremely helpful against him for high Unarmed skilled fighters , especially if they have the Paralyzing Palm perk . After the fights the entrant is considered " free , " and is given permission to meet Ashur in Haven . Appearances . The Hole appears only in the " Fallout 3 " add - on " The Pitt " . Behind the scenes . The Hole bears a striking resemblance to Thunderdome from the film " Mad Max 3 : Beyond Thunderdome " . similarities include the voice of the announcer as well as the structure of both arenas with the audience watching through the domes .
