It’s a little hard to decide what the new trailer for Mass Effect 3 is doing. There’s no real context for the battle scene that it drops you into in the trailer. There’s some gameplay but it doesn’t show off anything special except that Shepard can dodge things.
There’s also a big battle between a sandworm and a walking laser-shooting turret thing. So there’s that.
The plot of the game involves Shepard attempting to rally various alien civilizations to help combat the Reapers. Shepard will also have to deal with Cerebrus who have decided to betray him/her.
Mass Effect 3 will hit shelves on March 6, 2012 for Playstation 3, Xbox 360 and PC.
