Getting excited for Hero-Con? We are! So while there will be a shiny new Praetorian Clockwork Costume Code available for those who attend the event towards the end of October...we're going to start celebrating NOW by giving away costume codes of Cons past! Starting Today, October 1st all the way up to when Hero-Con starts, we'll be giving away anywhere from 2-4 U.S. and European codes each day! It's easy - all you have to do is make sure that you're following our Community Relations Team "CoH_OCR" Twitter feed: http://twitter.com/CoH_OCR. Watch for us to post a code, then be the first to enter it in into onto your account, and voila - it's yours! Here's a little bit of a twist. Sometimes we might post the code on our official Facebook page instead, so you're going to want to 'become a fan' of the game there and keep your eyes peeled: http://www.facebook.com/CityofHeroes Here are the codes you could win: 1.
