Thanks, Nekrocop! I appreciate the feedback. I used ElevenLabs AI to recreate Bill's voice from his in-game quotes. It's not perfect, but I managed to get it fairly close. I got better results with Zoey. No clue if they could be used in a mod...this was more of a proof of concept than anything else. I included the audio files in case anyone wanted to give that a shot.

Reallly impressive Yossarian! I assume you used an AI program. The voice is a bit off but in a game like L4D2 it probably won't matter much. Have you found a way to implement these lines in campaigns? Since they have no reference lines for these things said ingame, there's no files for you to replace in a mod sadly...
