With E3 in full swing, trailers for some very cool games are popping up all over the place. Here, Ubisoft looks to be going deep into the Marvel Universe with this trailer and stills for Avengers: Battle for Earth. The game, which in addition to a large roster of Earth's Mightiest Heroes will apparently also feature some X-Men, is scheduled for a fall release for XBox Kinect and Wii U.
