Fallout: Detroit 2103 is an side story of Fallout: Detroit and a mod idea centered on post-apocalyptic vehicular warfare. Set 26 years after the Great War, during the prime of the conflict between the Mechanics and the Highwaymen, the player takes the role of "the Driver" and must decide the fate of the Motor City Wasteland.
In the 26 years since the Great War, a group of people known as the Mechanics have been hard at work fixing Detroit. They've restored electricity to some parts of the city and maintain some semblance of law and order. They've built water purifiers for outlying farms and conduct soil tests and have repaired a number of vehicles to haul the crops to hungry wastelanders in Detroit. However a group known has the Highwaymen have constructed vehicles with the purpose of waylaying and plundering the food convoys. This has led to an arms race between the two groups, each building more and more battle-ready automobiles to outdo the other.
"The Driver", the protagonist, is a local street tough who enters an underground race held by the Highwaymen. After winning the race, the Mechanic's police units arrive and give chase to the Driver. Unable to get away, Security arrests the Driver and he/she spends the night in a cell. One officer remarks the Driver has some skill at driving and to let him know if the Driver wished to put them to good use, instead of dying for the Highwaymen on the Michigan Super Highway. After the Driver is freed the next day, a friend tells him/her that the Highwaymen were impressed with the Driver's skill during the police chase and want him to drive with them on their next raid. Thus a choice is thrust upon the Driver, one that will decide the fate of the Motor City Wasteland.
Compared to most places, Detroit is thriving in post-apocalyptia. Project: Aegis, a top-secret military program that deflected and redirected incoming nukes onto Canadian soil before they entered the U.S., saved the city of Detroit from total decimation. This has given the people a chance to rebuild, and rebuild they have. Detroit was an industrialized city before the War and its former factories have given the people the tools they need to restart civilization.
Detroit is run by the Mechanics, the name given by the locals to those involved in the rebuild effort. People from all walks of life have signed up with the Mechanics. From former Chryslus Motors engineers and Detroit Public Works officials to factory workers and welders. Their supply convoy vehicles are driven by former bus and garbage truck drivers. Order is kept by former members of the U.S. military and Detroit Police, driving restored cop cars. Even local governance has been restored; the Mechanics are led by the Mayor of Detroit, freely elected by the people.
The Mechanics' rebuild efforts are constantly plagued by the Highwaymen, a group of raiders who plunder the farms outside the city and attack the supply convoys. The two groups have been at war for years now and the road is their battlefield; each has an arsenal of battle-capable vehicles at their disposal. Their vehicles engage each other from the city streets to small country backroads, even the Michigan Super Highway itself, built for speed.
The Mechanics mostly began as groups of survivors came together to rebuild a life in the aftermath of the Great War. However one person is truly responsible for the success of the Mechanics, a former member of the Detroit Public Works. This person saw the chaos in the city after the War and tried to help the one way they could: fix the lights. The power lines still carried juice but the grid was down. It took three months to make the journey and complete the repairs but the DPW worker had completed their goal. This act brought hope to many. Soon individuals and settlements allied to the worker's cause and more things got fixed, the pinnacle of which may be stabilizing a DTF nuclear reactor that now supplies electricity to downtown Detroit.
Now the Mechanics govern Detroit, the DPW worker is now Mayor and in charge of a city-wide rebuild effort. They have accomplished much since the Great War. Most parts of the downtown area have electricity and purified water. They have established a linked trade network with outlying farms to supply the city with food. Police patrol the streets and trade routes. They pay scavengers for scrap and have shops set up to repair and resupply their vehicles. They've even restored functionality to a couple factories and repurposed them for their needs. The engineer designing their battle vehicles once had an 8-figure salary from Chryslus and the chief of police was a lieutenant in the U.S. Army.
- Management - Management are the leaders of the Mechanics and the city of Detroit. Management leads the rebuild effort from City Hall.
- Security - Formed from the remnants of the Detroit Police Department, security are the Mechanics' guards and their army. Security is responsible for keeping the citizens of the Motor City Wasteland safe and fight off the raider attacks on their supply shipments.
- Tech? - "Tech" is the Mechanics' science and knowledge division. From doctors to teachers. (Could be part of Maintenance. Technically doctors do maintenance. Characters like the Chryslus engineer could be shuffled to Management.)
- Maintenance - Maintenance is responsible for the upkeep of the Mechanics' equipment, from firearms and vehicles to factories. Maintenance also determines which derelict factories are worth refurbishing.
- Workers - Workers are the producers of the Mechanics. Workers smelt down scrap to forge new metal and work in the Mechanics' factories, as well as the farms outside the city.
- Scrappers - Scrappers are their scavengers, most often locals paid to plunder old buildings. Despite the name, scrappers look for more than just metal; chemicals and medicines are just as vital to the Mechanics' rebuild effort.
