Activision Blizzard really can take things to the next level. In lots of ways I wish I was playing call of duty as religiously as most other players. When I first checked out this field upgrade I was actually rather shell-shocked!
I love the control and feel of this Field Upgrade overall. It's just plain cool for starters and the transitions during gameplay are so, so very smooth. Love it! Hats off to the developers on another awesome item/Field Upgrade.
As far as usage goes, I am pretty new here. I'd say you would have to be very alert when using this Field Upgrade, as you always should be when playing COD. Next, it probably is better suited for a sniper. I am sure you could find other uses though.
When sniping/camping this could be your best friend, being the eyes in the back of your head!
