As was perhaps inevitable, BioWare has released a launch trailer for the Mass Effect 3: Earth DLC. The new classes, weapons, and areas are shown off, and the title will never not be a fun rhyme to say.
Anderson's narration in the trailer seems to insinuate the battle is going on concurrently with the story, as Anderson's rebel troops do battle. This does raise the question why there are Quarian, Geth, Asari, Turian, Batarian, and Vorcha troops available, but that's not important right now. What's important is that the new N7 troops are there, and they get the showcasing they deserve.
Anderson describes the people in battle as being the last line of defense, missing the opportunity to say, "against the worst scum of the universe," but viewers can see some of the heavy melee attacks, some swordplay by the Shadow and the Slayer, as well as the other classes laying out their own special brand of smack-down.
This trailer seems a little more exciting than the usual announcement ones, and it makes sense, because players are going back to Earth. That is, until the end, where new features are listed as unceremoniously as usual.
As always, you don't have to take my word for it, though. Take a look for yourself!
