Are you going to San Diego Comic-Con? If so, Ubisoft has some activities planned for you. These aren't your run-of-the-mill "let's go to a few panels" either (although you can totally do that if you want).
As promotion for Assassin's Creed Unity, Ubisoft is setting up a parkour obstacle course to let fans try their hand at some real assassin techniques (minus the stabbing, I'd imagine). Those that complete it will get an Assassin's Creed Experience t-shirt. There's also a 25-foot Leap of Faith that's separate, so as to not discourage anyone with issues with heights.
Other going-ons that Ubisoft has at SDCC are hands-on demos of The Crew and Just Dance 2015, as well as hands-off presentations of Unity. Also of note are panels whose subjects are Far Cry 4 and Unity. But, you probably won't have time for any of that as you muster up the courage to majestically dive head-first into uncertainty, just like your many ancestors before you.
