The bolts slows down any Vehicles it hits; and especially against raptors causes the vehicle to change orientation; throwing as opponent's aim.
The same is true of cicadas; and shock primary is the preferred foot soldier weapon against cicada
The shock secondary is far more effective at stopping Vehicles; and works very well against incoming mantas that are about to run you over.
Shock secondary also absorbs weapon fire; and can be used as impromptu shields.
Shock combos (Hitting a shock core with primary fire) - usually gives a one hit kill -especially if done from your opponent's blindspot; and he can't see it coming.
Your opponent must either be stationary - or you must predict wer he'll be; this prediction is a critical part of effective combat
Shooting 2 shock cores at slightly different angles will give your opponent even less room to move out of the way
Detonating a shock core just above a manta cockpit kills the pilot; and if initially undamaged will then give you a vehicle to drive.
Using shock combos is one of the quickest ways to demolish nodes on foot.
The shock rifle is probably the trickiest weapon to master; but soon becomes first choice for most situations
[edit]Tactical uses of the shock rifle in Deathmatch
To know how far your shock core has traveled; its glow on the floor gives an useful clue.
Aim just above your opponents head with a shock core; which will allow you to combo them; rather than simply hit them with the secondary.
