Unless you've been living under a rock, you'll probably know that yesterday, October 21st 2015, was a bit of a special date. According to legend, Marty McFly (from Back To The Future of course) arrived in the future on that date. And just in case you haven't already been beaten to death by people going on about it, Cryptic Studios and Star Trek Online are joining in.
Log in from now until October 26th, and you'll receive a "Future Flyer Powerboard", which looks suspiciously like the Mr McFly's preferred method of future travel.
If you want it, make sure to log in before Monday, as there's a good chance that it won't be available again. You can pick it up for free from the C-Store and have a blast pretending to be Calvin Klein. Beg your pardon, Marty McFly.
