About this filter

Alien: Isolation is a survival-horror game set aboard a decaying space station, and its dialogue reflects the desperation of the people trapped there. Engineers, survivors, and station staff curse under pressure — a sharp word when the Alien is close, a frightened outburst over the comms, an angry exchange when a plan falls apart. It is a deliberately tense, adult script. For some players that language is part of the atmosphere; for others it is a reason to keep the volume down. A clean-language filter lets you keep Sevastopol's dread intact while removing the spoken and on-screen profanity — useful for streamers who need broadcast-safe audio, for anyone playing with family within earshot, or simply for a matter of personal preference.

This patch covers both what you hear and what you read, in English. On the audio side, it filters 815 English voice lines: the flagged word is silenced while the rest of the line and the performance stay intact, and clip length is preserved so timing and subtitle sync are unchanged. On the text side, it applies 1,205 censors across 48 text files — subtitles, mission logs, terminal text, and UI strings — with sentence structure, punctuation, and spacing left as they were. It covers the F-word, S-word, B-word, A-word, D-word, and religious oaths used as expletives. It is English only; non-English text and audio are left alone.

The patch was built by scanning the game's English dialogue and on-screen text for profanity. Flagged audio was silenced at the level of the individual word, so the surrounding line and its delivery are untouched and each clip keeps its original length; flagged text was masked with same-length replacements so the on-screen layout never shifts. Your own files are backed up automatically before anything is written, and the result is reversible. The build was verified in-game on the Steam & GOG current build. Left untouched are the story, the voice performances, the sound design, the music, the gameplay, any non-English text or audio, and your saves and achievements — applied to your own legally-owned copy, this changes only the flagged English words and nothing else.
