We don't often post news about mods these days, but this is one we couldn't pass up. The modding community at No Mutants Allowed has been tinkering with the original Fallout engine for two decades, but one thing they somehow never got around to making was a BGT-style mod that would allow playing Fallout 1 in the improved Fallout 2 engine. Last July a group of experienced modders led by Lexx decided to finally do something about that. Yesterday they unveiled the release version of what they're calling Fallout et tu. In addition to importing Fallout into the Fallout 2 engine, it also implements many of the expected bell and whistles that modders have added to Fallout 2 itself over the years. Here are the details:

Fallout et tu

A Fallout to Fallout 2 engine conversion (also called Fallout 1@2, 1at2, or 1in2) brought to you by Rotators (the people who made FOnline: 2238 and stuff).

The aim of this project is to bring the first Fallout game into the engine of the second while utilizing Fallout 2's features wherever we can (within reason). Generally we do not try to make a 1:1 copy of the first game. So, if you want to play the 100% real deal, the very pure experience so to speak, you should grab the original Fallout 1 instead of this mod.

However, if you do not mind the one or the other change in mechanics, then Fallout et tu can be your way to go!

  • Replicates Fallout 1 in 2 almost 1:1.
  • Comes with the Hero Appearance mod integrated (Bald Dude, Long Hair Dude, Punk Girl).
  • Selected Fallout 2 weapons have been added (sparingly!) to the game world in ways that don't break the game balance.
  • Fallout 2 styled merchant inventory restocking (Optional).
  • Party members and generic NPCs can be pushed out of the way.
  • Party members level up and change their appearance based on worn armor.
  • Party members can be controlled in combat (Optional).
  • Automatic door opening and closing (Optional).
  • Traverse the wastes on your very own motorcycle (Optional)!
  • Continue playing after the main story has been completed (Optional).
  • Lots of bugfixes, making the game run more stable than even the original with patches.
Not to forget:

This project is a more accessible modding platform and allows the creation of complex modifications, which wouldn't be possible with the engine of the first game!​

I expect that Fallout et tu will become the recommended way of playing Fallout 1, superseding Fallout FIXT and the old TeamX patches. You can grab it at No Mutants Allowed or directly from its Github page.

I assume this also implements FO2's mechanical changes into FO1, like the new perks and the changes to how skills are calculated?

I dunno men, it's already crashed twice in the span of five minutes for me. Both times entering/exiting Shady Sands. Anyone else having issues?

The interesting thing is that I played Fallout 2 before I played Fallout 1 and I think I never even noticed a difference in the engines. Usually there's some type of negative transference going from the typically more enhanced/QoL later versions to earlier. So this mod would probably be wasted on me, but then again I'm not one of those wacky obsessives/autists that played the fallout games 100+ times either, so...

As Per pointed out in his guide, there are quite a number of convenience features in Fallout 2 that would be really nice to have in 1

  • There's no "take all" button (argh).
  • You can't move more than $999 at a time.
  • New items go to the bottom of your inventory instead of the top (don't they have playtesters to catch this sort of thing?).
  • You can't barter freely with party members.
  • You can't tell party members to move out of the way (or anyone else).
  • Your destination on the world map is reset every time you have an encounter.
  • "Rest until morning" only goes to 6.00 even though a lot of people in the game consider 7.00 or 8.00 to be the start of business hours, which is usually what you're waiting for.
  • Money isn't displayed in dialogue.
  • Carry Weight isn't displayed in inventory.
  • If you try to use something during combat, like opening a door or searching a corpse, your character will walk slowly up to it even if you have "always run" on.
  • You can't choose whether to avoid random encounters or not.

Though it's not worth it if it comes with a bunch of other changes.

I haven't thought about NMA in a while. Or Fallout modding for that.
I'm personally not sure about all of the changes, I might give it a spin.
Though in my diverse replays the Teamx fixes are the only 'modifactions'
I've used. It was interesting to read about some of the modding ventures,
but it was always the original for me.

But... Being able to push Ian out of the way... :lol:

This also means they ditched the "Tell me about" button and answers... Unless they implemented all those via regular dialogues somehow.

I'm actually wondering if they brought back the super mutants invasion. Always wanted to play Fallout 1 with that event enabled.

"Tell me about" feature has been built...

Here is the current features/fixes changelog -

  • Added: Fo1-styled red travel marker dots and terrain info when traveling on the worldmap.
  • Added: Mod - Resized Super Mutant flameboy death animations, originally by .Pixote.
  • Added: Mod - Fallout 1 interface mod. Replaces the Fallout 2 interface with the graphics from Fallout 1. This was originally a part of the fo1_base package, but is now its own thing for easier handling.
  • Added: Mod - First iteration of the german translation. All vanilla Fo1 core-dialogues are finished. Some of the new sentences aren't translated yet, and added dialog files from the old TeamX restoration mod, etc aren't translated yet either. Any help with finishing the translation is welcome!
  • Added: Mod - Classic Worldmap mod will now uncover and show locations the same way as in Fo1.
  • Added: Mod - Classic Worldmap special encounter blinking icon is now the same as in Fo1.
  • Added: Animations - Missing "exploded to nothing" / "Chunks of Flesh"-animations for rad scorpions (big and small).
  • Added: Animations - Missing running animation for female tribal NPC.
  • Added: Animations - Missing SMG idle animation for black metal armor dude.
  • Added: Animations - "Black" Combat Armor animations for the Brotherhood Armor. Works for players and party members. The style can be toggled on/off for Brotherhood NPCs in the fo1_settings.ini file.
  • Added: Animations - SMG and Pistol animations for "Yellow-Pants" metal armor woman.
  • Added: Animations - Rifle animations for Black Metal Armor Dude, because why not.
  • Added: Animations - Tycho-critter can now also use SMGs.
  • Added: Animations - Loser with black shirt animations (Unused for now).
  • Added: Animations - Black Man with black shirt animations (Unused for now).
  • Added: Fallout 2 dialog interface graphic with "Tell Me About"-button.
  • Added: Fo1-styled interface graphics for Sfall's "ActionPointsBar"-mode (increases visible action points on the interface from 10 to 16).
  • Added: German translated interface graphics for Sfall's "ActionPointsBar"-mode.
  • Added: Zones around the Glow read "Rad. Mountains" / "Rad. Desert" (can't show full text length right now).
  • Added: Being in encounter maps in the zones around the Glow will radiate the player a bit, not just the traveling on the worldmap.
  • Added: "Out of Business"-sign will appear outside of Darkwater's store after Killian has been assassinated.
  • Added: Except for the squad leader, all generic Brotherhood paladins in random encounters will wear helmets (makes it possible to identify the leader without having to click on everyone).
  • Added: If the player has more than 1 radscorpion tail, Razlo in Shady Sands can craft antidote from all of them at once.
  • Added: Razlo's kids will return correctly to their home after dark. Also tweaked their dialog so they won't say they don't know where their parents are if they are right next to them.

I assume this also implements FO2's mechanical changes into FO1, like the new perks and the changes to how skills are calculated?

Perks are in, except for a few stupid ones that I have removed. Level cap is 21 so you probably won't see most of them either way.

Skills are calculated in the same way as in Fo1.

As others mentioned before, "Tell me about" has been recreated by us (said to be impossible), and even expanded upon. We also added in "impossible" stuff like red dots and terrain info to the worldmap.

Do you get a memory error? If so, what does it say?

Searching for my kidnapped sister

Downloading as we speak~

NOTE: now to find the iso files in my HDD because boys, after two decades and several times getting rid of legacy of CD/DVD, I no longer have any of that. Still have F2 iso on HDD but F1 is hard

You should add an option for using the FO2 method. The change to how skills were calculated was an improvement, making your attributes play a bigger role.

Just delete the skills.ini file in /config/ and it'll use the Fo2 calculations. Personally I don't like it, though, because it dramatically changes the games difficulty. For example in Fo2 you start with a very high outdoorsman skill, while in Fo1 you don't, etc. stuff like that is influenced by the calculations.
