I'm inclined to believe it's the latest build of the game. The boombox shoots AP all over the place like in the latest comic-con footage of the game.
Latest build as a lot more characters, fyi.
The boombox also shoot AP all over the place in the E3 videos, he just didn't use it as much, since it's a "when you're alone" item, to gather some easy AP, while the other 3 are fighting.
Haha that looked like tons of fun! After watching the video 2x I've come to this conclusion;
-Smooth Gameplay 60fps
-Soundtrack is awesome
-Everyone is fairly balanced
-graphics are great
I can't wait to have my hands on this!
