Can't wait to see a hacker use that

Details of what the idea is Stefan.
Is it a dual weapon?
How much energy?
Can another weapon be used at the same time?
Does it have a ammo limit? (If not then its a dumb idea since you'll see people using it constantly)
For some reason I have a feeling this idea is going to be incorporated into the laming of the game, by having people lame then when opponents spawn they activate a shield and so they can't be hit by opponents can.
