I took a cursory glance over at Please include your system information as requested at https://github.com/ValveSoftware/Source-1-Games (which is where we prefer HL2 bugs be posted) and I don't see anything there.
Update : This has been solved with the last update.
Thank you.
Nothing extracted yet.
Hello.
I completely re-finished the game with it's release on Linux. At the end of the game, when you have to destroy the teleporter and the announcer tells you "x seconds before singularity", nothing happens if you try to let Dr. Breen escape.
I could not test if reproducible on Windows with the last update.
I did not try the last beta update of Half-Life 2, but since I have not seen this error reported anywhere, I post it here.
