📋 About This Mod
"Lost Soul" is a Railroad radiant quest during which you are tasked with delivering care packages to synth refugees following the Institute's destruction. Although there is nothing wrong with the quest itself (as far as radiant quests go), it does have one glaring shortfall; namely, the synths you rescue share a pool of only four faces (two male and two female), and since the quest is repeatable, the synth refugee faces will eventually repeat as well. Lost Soul Expanded takes a page from my "Diverse" series and expands the number of synth refugees to 20 (see screen shots), dividing them evenly among males and females. Since the quest selects a refugee at random, and the expanded face pool is finite, repetition will still happen, but the likelihood is now significantly lower.
Lost Soul Immersion Packs
Located in the Optional Files section, there are two "immersion packs" that bring more variation to the synths, although at present, they only add height scaling so as to make them consistent with the immersion packs I've made for so many of my other mods.
The first immersion pack, called Lost Soul Expanded Immersion Pack, only requires the main Lost Soul Expanded file.
The second immersion pack, called Lost Soul Immersion Pack Alt requires the main Lost Soul Expanded file, as well as Rescued Synths Go to Mercer Safehouse (by abd3nj), Lost Soul Quest Tweak - No Faction Hostility (by Babaloo123), and the patch in the latter mod's optional file section called R. S. G.t. M. S Patch (Expanded), which makes all three mods work together. You don't need the first immersion pack if you are using this one (and vice versa).
Compatibility
This mod should be compatible with anything except mods that touch the same quest.
Special Thanks
