City of Heroes Issue 17: Dark Mirror has moved into Open Beta and players who have been itching to check out the latest update for the superhero-based MMOG can log into the North American or European Training Room (Test Server) to give the latest update a try. If you're unfamiliar with how the Test Server works there is a useful thread on the official CoH forums that will guide you through the process. Issue 17 will introduce Ultra Mode, a new superior graphics rendering process, Epic Archetypes unlockable at level 20, new story arcs, and a host of other content. Issue 17: Dark Mirror is scheduled to release later this month, but why wait. make your way to the Test Server and check it out now.
