[edit] Essential improvements

[edit] Skip intro videos

  3. Find the following lines

Replace them with:

Information Changing the setting bForceNoMovies to TRUE will not work because the game will fail to load anything past the main menu.
Advantage You can use a scripted .bat file for this process (place the .bat in the Config folder as written above and run it).
Advantage Enemy Within does not have this problem, but if you chose to start Enemy Unknown after installing EW the problem still persists.

[edit] Turn off multiplayer chat

Some users may be using an alternate VoIP program (Ventrilo, Mumble, TeamSpeak, etc.) to chat while playing multiplayer, and may wish to turn the in-game chat off. There is no in-game setting to do so, but by editing an INI file, you can turn off voice chat.

Fix Turn off multiplayer voice chatLink

  1. Open %USERPROFILE%\Documents\My Games\XCOM - Enemy Unknown\XComGame\Config\XComEngine.ini
  2. Search (Ctrl+F) for VoIP in the file
  3. Change the line bHasVoiceEnabled=true to false
  4. Save and close the file

[edit] Enable armor tint options

Fix Enable armor tints[2]Link

  1. Open %USERPROFILE%\Documents\My Games\XCOM - Enemy Unknown\XComGame\Config\XComGame.ini

[edit] Save game slowdowns
