I feel like having your character be evil or die no matter what would have sucked ass for a game like this no matter what but here are so many reasons this doesnât work for Fallout specifically and for this plot specifically.
Fallout is famously cavalier about the actual effects of radiation on the body and one of the reasons for this is that thereâs so much medicine that can treat radiation poisoning that you can buy it at any doctorâs office. I forget if it was in this game or not but you can literally craft it out of mushrooms in some games. How tf did a booby trap gather enough radiation to kill you when actual nuclear waste wonât? You can detonate an actual nuke earlier in the game and the resulting fallout (heh) wonât kill you as quickly as this shit. You have a tiny Davey Crocket nuke launcher that leaves radiation and it barely touches you. There are multiple items that make you absorb less radiation including the trademark power armor.
One of the main villains escaped with his life when this chamber was flooded with radiation in the first place. Didnât even have a hazmat suit.
In addition to Fawkes, you also have a robot companion named RL3 you can get. While his refusal in the base game is a bit better written than Fawkesâs, he also literally should not be able to refuse.
The radiation was a trap to stop the Enclave from activating the water purifier. The reason they want to activate it is so they can ration clean water as leverage to take over the Capital Wasteland. How did he expect us to turn it on afterwards?
To activate the purifier, you need to clear out the Enclave occupying it. What was the point of not letting them turn on the water purifier if weâre gonna have to take it back anyway? Itâs powerful enough to purify the whole Potomac and water is a renewable resource once you can do that. It doesnât matter if they get a little bit of the water out before we do this. This man died AND got us killed for NOTHING. How are we meant to get in there to do maintenance?
THE GAME DOESNâT GIVE YOU THE FUCKING CODE FOR THE PURIFIER IN YOUR QUEST LOG! Youâre supposed to infer it from the Bible verse your dad uses several times throughout the game. Which would be well and good if there were literally ANY other point in the game where you had to make that sort of inference, but itâs not that kind of game! Stuff like thatâs in the quest logs! The only way to actually get the code is 1) see a dialogue option where you tell the villain (getting you shot after) and remember it for later (again, why would you? The game usually notes these things for you) or 2) pick the option to sacrifice the only person whoâll actually do it, tell her the code, see it in the dialogue box, wait for the ending to insult you, then load a save God knows how far back. I think you may also be able to say youâre sending her in there, read the dialogue, and change your mind, but then you still gotta be an asshole.
Also they didnât change the ending narration when the DLC to change the ending came out so Ron Perlman still calls you a bitch for sending in someone whoâll actually live.
Also when you have the DLC, when you ask an immune companion to activate the purifier, they go âoh lol yeah. I canât die from this. Good idea!â
âSorry human, but no. My fingers are too big to use the keypadâ would have been less stupid.
