A gun that shoots a dart at a player and renders then unable to aim correctly (see Seismic Transmitter). This exists in real life, used for riot control and day to day police work(at least in the U.S.A).
--Advantages--
-renders enemy unable to aim for 4-6 seconds
-fired like bullet, if you have good aim then you are good to go
--Disadvantages--
-limited amount of darts
-cannot cause actual harm, must switch to normal weap to cause damage
-replaces knife (slot 3)
-costs 5 credits(because it can mean difference between life or death in close combat)
and NO, this is not similar to http://community.deadm.com/viewtopic.php?t=954
