I have the bundle but not the titan quest, how can I get it??
Use your personalized bundle URL to navigate to the page with the games. It is listed as a Steam code and you activated it through Steam. The URL is in the email received when purchasing the bundle and is sent to the email address used on step four of the purchase. You click the Steam icon next to the Titan Quest title in the URL page and it will reveal the code to activate within Steam.
