Special ability : " Quantum Matter Manipulation ". An AOE effect around the owner of the suit slows down all players movement to a set speed ( Both movement speed and mouse DPI ) bringing it nearly to an halt for several seconds.
Another idea would be sort of like the nano cloak, except this time it would act as a " repeller " making anyone who lands a shot on the player while the cloak is activated to have his aim shaken ( Sort of like when you get t-gunned ).
A suit that is bullet proof in certain areas (and is non-rippable like the edf suit) ie. if you get shot in the chest or back you take 0 damage so you need to get shot in the legs or head, this can be made into two versions, one for cops and one for the rest. Additionally this could simply be added to the terroriser outfit since it already has the armor plates on it.
