Hoover Dam design document / 3 This is part 3 of the Hoover Dam design document for " Van Buren " , the canceled " Fallout 3 " by Black Isle Studios . Monster Roster . Commoner - # ~ 15 , Lvl : 5 - 8 . Common townsfolk in Hoover Dam . Some have crude weapons , some don ' t . Rad Scorpions - # ~ 5 , Lvl . In this radioactive region , it ' d be an impossibility not to have some rad - scorpions lurking about in a random encounter . Nothing special about these guys , they are your typical rad - scorpions . Cockroach - # ~ 5 , Lvl . Cockroaches of unusual size are abundant in this region , and are one of the primary ingredients for the Reservation ' s version of Rad - X ( once the player finds the Reservation ) . About the size of a Volkswagen beetle ( pun intended ) , these giant pests can be very aggressive . However , should the player want to go hunting for these critters , the ghouls of the Reservation pay handsomely for cockroach gizzard s . Endless Walker - # ~ 2 , Lvl . Due to their prolonged , open exposure to the desert sun , high radiation , and other hardships of the wasteland , these unfortunate ghoul s , who were banished , naked , from the Reservation , look like walking , sun bleached chunks of beef jerky . Their minds are almost completely gone and they react mostly on instinct . They will attack the first thing they see moving in a vain effort to quench an appetite that can never be quenched . Also , their skin in very tough and they strike with their claw - like hands with surprising quickness . Fortunately , endless walkers do not travel in groups . In fact , it is a rare occasion when someone comes across one , though most who travel this side of the wasteland like to keep their distance from the voracious creatures . Giant Albino Ant s - # ~ 20 , Lvl 3 - 6 . These horrific ants have adapted almost too well to the dark and toxic halls of the Scum Pits . Their exoskeleton is a translucent blue / white , their eyes glow red , and their lethal mandibles secrete a toxic green poison . Giant Albino Rat s - # ~ 15 , Lvl 3 - 6 . Another critter that seemed to adapt well to the dark and toxic realm that is the Scum Pits , the giant albino rats are an important part of the twisted ecology . These rats are a bit tougher than regular giant rats / pig rats / donkey rats / elephant rats / Delta Burke hoarding chocolate . Their bite is poisonous , but only half as toxic as giant albino ants . They are about the size of a great - dane , have very pale , yellow tinted skin , and red , glowing eyes ( everything scary must have red , glowing eyes ) . NCR Troops - # ~ 20 , Lvl : 8 - 12 . These are the troops that accompanied Governor Dodge to Hoover Dam . They are under the direct command of Major Fleming . The NCR troops are armed with high powered rifles , grenades , and combat armor . Crimson Caravaner s - # ~ 5 - 8 , Lvl : 5 - 8 . Aside from the well armed escorts , the caravaners from the Crimson Caravan Company look fairly unassuming . Groups consist of three or four normally attired carvaners carrying small firearms , and two to four heavily armed escorts . If the player wants to trade with them , and the player is on neutral to good terms with the Crimson Caravan , then they will be happy to trade . If the player established a hostile reputation with the Crimson Caravan , then the escorts and caravaners will attack the player on sight . 3 - Some Caravaner s - # ~ 5 - 8 , Lvl : 5 - 8 . It ' s very difficult to tell a 3 - Some caravaner from a hired escort . All are armored and carry at least a decent firearm of some sort . At first glance , these caravaners could be mistaken for raiders . If asked , they will say because of the frequent attacks by BOS , they must be heavily armed and always ready for battle . If the player wants to trade with them , and the player is on neutral to good terms with the 3 - Some Caravan , then they will be happy to trade . If the player established a hostile reputation with the 3 - Some Caravan , then the escorts and caravaners will attack the player on sight . Hoover Dam Police - # ~ 8 , Lvl : 8 - 12 . Similar to look and spirit of the Texas Rangers of yesteryear , the Hoover Dam police pride themselves on keeping the peace . They dress in distinctive beige trench coats and black cowboy hats , so they are pretty easy to separate in a crowd . Also , their ability to remain stone - faced through all adversity and pleasures is truly awe - inspiring . Giant Leech es - # ~ 20 , Lvl : 6 - 9 . The Scum Pits are also occupied by giant leech es that swim in and out of the large holes in the ground where the power generators used to be . These leeches are the size of a full frown pot - bellied pig and have been known to suck out enough blood to kill a super mutant . These critters are very slow and will attack on site . They also attack the giant albino rats in the Scum Pits . Trog s - # ~ 15 , Lvl : 6 - 9 . Before the big war , there were hillbillies . These people lived far away from civilized folk and fended for themselves in the wooded mountains . During the war , a lot of hillbillies reckoned it might be a plum good idea to head for the nearest caves and wait out the fiery mushrooms . Since the hillbillies were far removed from a lot of the nuclear blasts and subsequent fallout , especially being holed up in caves , the hillbillies fared pretty darned good . In fact , the hillbillies took to cave dwelling so well , they made caves their permanent home . Over the course of a couple of centuries , the isolation from the light , combined with ever so slight radiation that drifted over the world and managed to seep into caves , caused the hillbillies to change a slight bit . Their skin became a dull yellow / white , as well as their hair , as a result of the loss of melanin . The trade - off was that their skin got a tad thicker , which made them more resilient to cold and hardships . So , when some of the hillbillies first ventured out from their cave dwellings after two - hundred years , it came as no surprise that they could not tolerate direct sunlight very well . Smarter folks who saw the hillbillies started referring to them as troglodyte s , but since most people of the wasteland were comprised of ignorant twits , the term " trog " became more accepted . Even the hillbillies referred to themselves as trogs . The trogs of Hoover Dam were nomadic at one time thanks to a cave - in at their previous dwellings . Before Dodge and his troops came to Hoover , Billy - Bob and his trogs took up residence in Baseline , figuring it was pretty secure from caving in . No one argued with the trogs , and when Dodge came to Hoover , he asked if they would help out Otto with the maintenance in exchange for food goods and water . The trogs accepted and have been content ever since to mosey around Baseline making sure every light was flashing correctly . Random Encounters Surrounding the Area . Cockroach Minor Encounter . A small nest ( ~ 4 – 6 ) of giant cockroach es are mucking around in search of food . They will seek to attack the player at first sight . Rad - Scorpion Minor Encounter . A small nest ( ~ 4 – 6 ) of rad - scorpions are mucking around in search of food . They will seek to attack the player at first sight . Endless Walker Encounter ( very rare ) . Not all Endless Walkers end up scorpion food , at least not at first . On those rare occasions when one survives more than one year in the wasteland , they turn into wandering , voracious creatures on an endless quest for flesh . Their constant exposure to the hot sun and high levels of radiation has caused their skin to toughen into natural , hardened leather , but at the same time , their brain has completely cooked . Endless Walkers who have been in the wastes for so long become a creature of instinct and will attack anything that moves , especially the player . Though encounters with Endless Walkers in these parts are rare , when someone does encounter them , they are assured to never forget the encounter , if they survive . Crimson Caravaners - Intermediate Encounter . Aside from the well armed escorts , the caravaners from the Crimson Caravan Company look fairly unassuming . Groups consist of three or four normally attired carvaners carrying small firearms , and two to four heavily armed escorts . If the player wants to trade with them , and the player is on neutral to good terms with the Crimson Caravan , then they will be happy to trade . If the player established a hostile reputation with the Crimson Caravan , then the escorts and caravaners will attack the player on sight . 3 - Some Caravaners - Intermediate Encounter . It ' s very difficult to tell a Crimson caravaner from a hired escort . All are armored and carry at least a decent firearm of some sort . At first glance , these caravaners could be mistaken for raiders . If asked , they will say because of the frequent attacks by BOS , they must be heavily armed and always ready for battle . If the player wants to trade with them , and the player is on neutral to good terms with the 3 - Some Caravan , then they will be happy to trade .
