If you’re a superhero fan, there’s a slight — slight — chance that you’ve heard of this Avengers: Age of Ultron movie that’s coming out soon. Seeing as how there hasn’t been a Marvel film in the past couple of years that Gazillion hasn’t cross-promoted, Marvel Heroes will indeed be piggybacking on this movie event with an event of its own.
Marvel Heroes has begun the first phase of its Avengers Assemble event, which allows you to play any of the Avengers (but you can only take one up to level 60) and enjoy a 50% XP boost while on those characters. Other facets of the event include attacks by Ultron sentries, Avengers mystery boxes, and special boosts that stack if you’re partied up with others who also sport the same bonus.
The studio is also selling costumes from the new film. It remains to be seen what will transpire with future phases of the event.[Source: Marvel Heroes]
