DC Universe Online Previews

DC Universe Online has been on display at E3 and a couple of sites share their impressions of the superhero MMO. GameSpot.
The demo took place inside one of the game's episodes. Episodes are essentially story arcs in which you join (or fight) well-known characters from the DC universe. The episode we saw took place within an amusement park run by The Joker (of Batman fame, obviously). The player's goal? Defeat Harley Quinn and rescue Robin, the Boy Wonder, who seems to be having a hard time extricating himself from his own sticky situation. (As a side note, there were several humorous references to the Boy Wonder's apparent uselessness, which makes us hopeful for lots of funny, tongue-in-cheek dialogue from our favorite superheros.) The bosses you fight and heroes you assist will change as you progress through the game. You'll start by fighting off lesser villains, but eventually, you'll be taking on the big boys. So while Harley Quinn will put up a fight, you can expect an even bigger one from The Joker himself.

Another interesting thing about the environment is that there are a lot of objects and facets of the world that are destructible and which could either prove to be a help or a hindrance for you. Giant billiard balls could be dislodged in the map causing them to madly roll around causing damage to anything in their way. If you're quick on your feet, you could acrobat your way around them while trying to line them up to hit enemies that aren't quite as nimble as you are.
