Did it launch with bugs? Yes. Does it have a couple issues? Yes. But it is a free total conversion for FO4 and it does a great job at delivering a completely fresh experience. Many $70 games release with game breaking bugs and poor optimisation and somehow this massive in scale passion project is able to run relatively smoothly. The work put into just the new world that was created is absolutely stellar. The environments in this game are better than anything Bethesda has ever put in one of their games. The voice acting is solid. The weapons are awesome. This doesnt feel like a Fallout 4.5, other than being in the same engine, it infact does not feel like or look like fallout 4 at all. This mod eclipses vanilla FO4, it is insane how an unpaid fan project is somehow better in quality and detail than a AAA release with millions of dollars behind it. If you have not played London yet and own Fallout 4, you are doing yourself a great disservice. Correct your mistake and install Fallout London today!
