A solitary radio half-buried in the sand flickered to life under the shade of an untouched beach umbrella, a soft and calming tune
lazily flowing out. Beside the portable radio, an unburnt but ages-old skeleton rested, face-down on a towel sunbathing under the yellow skies. Further away, the shriveled husk of a leafless palm tree offered shade to another fleshless corpse reclining in a wooden beach chair.
In the distance, the wasted toxic soup of the Pacific cascaded on- waves tumbling over one another as they ebbed and flowed onto the beach. Past the beach, there was a debris-strewn road and boardwalk, vehicles stationary and lifeless, their occupants still skeletonized within. Rather than being obliterated and wrecked apart, every person, ever building, every thing was dilapidated and abandoned, rusted and degraded. It started to rain softly... The sound of the cascading ocean and pitter of black rain fought with the soothing music until it started to repeat, that melodious women's voice unnaturally caught in a second-long loop until the signal abruptly tuned out.
All that remained was the sound of the waves lazily rolling forth from the sea before they retreated back to the ocean. That and the gentle deluge of acid rain that steamed on contact with the earth.War. War never changes... In the year 2077, fire rained over earth and humanity was irrevocably changed forever. Those who survived would never again live their lives as they once did, doomed to rule over the world that they destroyed. The end of civilization lasted only two hours. No one knows who shot first, but within moments most of the world was scorched in a hellstorm of radiation. Yet not all was entirely lost. On the island of Oahu, those who survived did so in great underground vaults. As they hid beneath the earth, China, only a stone's throw away, blanketed the island in a deluge of chemical and biological weapons, sparing the tropical paradise the horrors of nuclear holocaust while inflicting upon it a much more insidious fate...
One day, in Vault 88... there was someone at the door... And they were trying to get in. The sound of heavy equipment and blow torches cutting through the heavy door was an ominous reminder to the inhabitants within that they were not alone. The noises from behind the door continued for days, until at last- it finally stopped. For a week, there was nothing.
The Overseer decided that this bizarre event could not be ignored. You have been chosen to brave the wasteland, to exit the Vault through a secret hatch, reconnoiter the main vault door, and report back your findings...
Not all players need to be from the vault. Moreover, not all players need to leave the vault. I am considering showing some life inside the vault, if I can. Maybe one player could leave and check on the main door while another anxiously awaits the news and deals with the paranoid Overseer. A third player, meeting the first one not long after he/she leaves the vault, could be their guide. Eventually, all three of them will explore the wasteland together.
Well, that's just one idea. The Overseer will likely kick the 'explorer' out, telling them to figure out what's going on as a ploy.. or just blame to prevent 'contamination', the second vault dweller could be a friend or lover who will follow him/her in exile.
So, the thing about Vault 88. When it was first closed, the inhabitants were continually given a cocktail of aphrodisiacs on a daily basis. The vault itself was designed to resemble phallic or yonic imagery and plenty of provocative reading/viewing/listening material was available. Vault-tec's experiment was all about examining the consequences of free love.
Over a few generations, the inhabitants grew a tolerance to these chemicals pumped into their system, themselves becoming walking aphrodisiacs. Vault dwellers' sweat, spit, and sexual fluids are saturated with chemicals that arouse the passions of people (or creatures) who are not accustomed to the aphrodisiacs like they are. Moreover, there is a culture of sex. Vault 88's trash incinerators are primarily burning many, many, many, many condoms.
As for what life is like outside the vault, that information is for a PC playing that role only. Though I will reveal this much; No nukes actually fell on Oahu. Just chemical weapons, and maybe a little bit of accidents involving the US Army's supply of FEV. So, day 1 after the war- everything was sill probably functioning. Automated power plants and the like... if they are nuclear- then they might have continued working for a long, long time. Of course, this is Fallout and without human intervention, something had to go wrong.
