look at 3:15 and put the quality to hd and look and his back no AA hmmm maybe something maybe it only some gametypes
Are you talking about the integrated thruster pack we saw in the trailer?
Yah, not AA’s. AA’s in their total suckage can be defined as interchangable abilities that add -Yoink–nothing to gameplay because with no one consistent set for all players in all situations weapon balance and map layouts cannot be made to fully accommodate for them, or take advantage of them. Thus they are left as token gimmicks which could have easily been thrown away without affecting the core game because they weren’t incorporated in there to begin with.
Sprint and maybe a little woosh doesn’t fall into that here because they are/would be consistent for all players. That isn’t to say that I’m excited for what every single -Yoinking!- game has added onto to it’s movement scheme since COD became popular despite itself, but it’s not necessarily bad move for Halo 4 in particular.
