📋 About This Mod
Mothership Zeta Rehaul
🏳️🌈🏳️⚧️A complete polish pass over the Mothership Zeta DLC, improving interactions, crafting, post-dlc content, cross wasteland capability, bugfixes, and other tweaks.
Note that the changes below aren't exhaustive, some things I may have forgot to document. There's a lot here.
Starting the DLC
- The crashed ufo before you start the DLC will no longer forcefully teleport you to the ship, instead an objective is given to you upon approaching the ship to "examine" it, requiring the ship to be activated and a confirmation upon reading a message, like New Vegas DLCs. This allows the crash site to be explored and looted without starting the dlc, as was in Fallout 3's base game.
- Alien-related TTW challenges now only start upon starting the dlc or collecting related items, limiting exposure to alien stuff if you choose to never start the DLC.
- An ini option has been added to allow you to disable the crashed alien spacecraft if you don't have Wild Wasteland, making the Mothership Zeta DLC exclusive to the Wild Wasteland trait, if that is how you prefer it to work.
- Fully compatible with Delay DLC Redux or Locate Radio Signals mods.
Starting from Mojave Wasteland
- Mothership Zeta can now be started from the Mojave Wasteland. Upon entering the Mojave Wasteland for the first time, a message will display about it, and an objective will be added to your pip-boy pointing to the location in the Mojave. Can be delayed if Delay DLC Redux or Locate Radio Signals is active, and starting from the mojave can be disabled entirely with an ini option if desired.
- The Wild Wasteland encounter north of the Horowitz farmstead has been altered, and will trigger regardless of if you have Wild Wasteland or not. Can be reverted to be Wild Wasteland only via an ini option.
- The encounter's mercenaries will initially spawn, however as you fight them the alien ship will crash to the ground and will spawn the aliens.
- The aliens will fight with the mercs and use alien weapons. The captain uses the alien captain model from the DLC to differentiate it from the other aliens and uses a nerfed non-player alien blaster to fight you and the mercs. Looting this alien blaster off this alien will still reward you with the original alien blaster.
- The crashed ship works just like the Capital Wasteland one, with the alterations introduced by Mothership Zeta Rehaul. An objective to examine it is added, the crashed ship has to be activated, and a confirmation upon reading a message to start the DLC, just like New Vegas DLCs.
- If you start the DLC from the Mojave Wasteland, the Rivet City Security and dead Enclave Officer will be replaced with an NCR Trooper and a dead Legion Explorer. With the initial sight of familiar factions to Fallout 3 replaced with those found in New Vegas, this shou
A complete polish pass over the Mothership Zeta DLC for Tale of Two Wastelands, improving interactions, crafting, and other tweaks. With 494 endorsements and nearly 150k downloads, it's a well-received overhaul for players wanting a refined experience.
