The article text provided is only the site's navigation and membership boilerplate from PC Gamer — it doesn't contain any actual content about the Nier mod itself (no details on the modder, the "Father" content being restored, or the voiceovers mentioned in the headline). I can't produce an accurate summary without fabricating details that aren't in the supplied text.

If you can provide the full article body (or the URL content can be re-fetched), I'll summarise it properly. Alternatively, based on the headline alone, I can note that this concerns a modder restoring an early/unused version of a character called "Father" — believed to relate to Nier or Nier Replicant/Nier Automata's PC remaster — including its original voice lines, but I'd be guessing at specifics rather than reporting them accurately.
