Patch history[edit]

Patch
Description

  • Added all sound directories to the whitelist for -enable_addons
  • Updated -enable_addons to include sound scripts, music scripts, and Flash videos
  • The use of –override_vpk is no longer allowed in matchmaking games in order to prevent gaining a competitive advantage.

February 02, 2015 Patch Update 2
