4. Force Fields/ Shields
This is going to be a short one, but to put it simply its a good accessory for completely obvious reasons. The force-field shield would give one the ability to walk the streets without fear; simply down to the fact that at the first hint of danger - BOOM - up goes a force shield. Safe inside your glowing blue ball you could walk the streets in peace, absorbing your enemys bullets as you move in for the kill, although if you lived in an area where that was common place, I would advise seeking somewhere else to live instead of this gadget... One thing I have always wondered is what would happen if two force shields collide, Im imagining a scenario where they are both propelled in opposite directions with an ear pleasing jolt.
