Mass Effect writer Mac Walters will be participating in a live Twitter chat event with Dark Horse Comics on December 20th at 11am PST. Anyone can watch or join in by using the #MEComicsChat hashtag. Although it is overtly a promotional event for the release of the latest issue of Mass Effect: Invasion, questions about the games seems to be allowed as well (he is the lead writer on the 2nd and 3rd games as well, after all). As an incentive for participating, Dark Horse is giving away 10 digital copies of the new Mass Effect: Invasion #3 issue! I've added the chat event to the calendar listing on the sidebar, although I converted the starting time to EST.
