I replaced about 150 files of the TF2 announcer with Portal’s GLaDOS. Most samples are from the Dota 2 announcer pack.
Yes it’ll work on Valve servers, and servers that’re svpure 1. If you find any issues, or got a better idea let me know, I’ll update the pack.
Also this pack does not include lines for MvM, Passtime, Mannpower, Robot Destruction, or Halloween modes.
