Yes there can be pvp.
Right click on your Titan Quest startup icon and choose Properties down at the bottom. Under the Shortcut Tab the third line should read:
Target: "C:\Program Files\THQ\Titan Quest\Titan Quest.exe"
Change it to:
Target: "C:\Program Files\THQ\Titan Quest\Titan Quest.exe" /pvp
You will now only see pvp online games, and can engage, defeat and flame non-partied members of the game you are in.
Cheers and watch out for me,
