📋 About This Mod
===========
DESCRIPTION
===========
This is a Tale of Two Wastelands conversion of my Fallout 3 mod Rebuild the Capital. Now compatible with TTW 3. 4
Note the Fo3 version is not supported and has not been updated since 2020. As such, much of the content in the TTW version is not present in the Fo3 version.
Rebuild the Capital is focused on expanding the Brotherhood of Steel and their role in the wasteland following the events of Broken Steel. Rather than sit on the sidelines after establishing dominance in the wasteland, the Brotherhood can spread across the Capital Wasteland under the guidance of the player. The Brotherhood can bring settlements under its protection and can build military installations in wastes and the D. C. ruins. The player can help rebuild Grayditch, establish more Brotherhood patrols, and turn Adam's Air Force Base into an impressive base for the Brotherhood of Steel. The mod also adds a large assortment of weapons, armors, perks, and NPCs. The mod also features several new quests that deal with reunifying (or destroying) the Outcasts, finishing off the last of the Enclave, the relationship between Ghouls and the Brotherhood, and continuing the fight against the Super Mutant threat. Lastly, Rebuild the Capital includes a new recruitment system that allows you to recruit combat squads that will accompany you on your exploits. Overall, this mod is not meant to overhaul the game, but rather to serve as a companion piece should anyone return to Fallout 3. Lastly, this mod was inspired by mods like Mothership Zeta Crew and other great mods that keep breathing life into this very old game.
===========
GETTING STARTED
===========
I would recommend that you start a new game for this mod due to the many changes it makes. You can access the bulk of the mod's content after completing the quest "Who Dares Wins" featured in the Broken Steel DLC. After completing the quest (without destroying the Citadel), speak to Elder Lyons about planning the future of the Brotherhood. You will then complete two short quests before you are moved to Adam's Air Force Base where you can access to the majority of the mod's features.
===========
CIVILIAN AND MILITARY INVESTMENTS
===========
A big part of this mod is "investing" in settlements and military bases.
Investing settlements brings in taxes that provide revenue for future in investments. These taxes can also be used to invest in the military expansion of the Brotherhood. The more you invest in the military, the more Brotherhood campaigns you unlock. In order to invest in most settlements or military structures, you need to complete a related quest. For example, to invest in Megaton, you need first to defuse the town’s bomb. To invest in the Lincoln Memorial, you must first complete the quest “Head of State.” And so on.
