Shotgun 1 hit kill
In Killzone (multiplayer or single), when you have the shotgun and you are aiming at an enemy, press the primary and secondary fire at the same time. This will fire three shells at one time, capable of killing an enemy from around medium distance. Be warned, however. After doing this twice, you have two shells left, providing less power. This runs your ammo down pretty fast, so try and use it in places like Park Terminal, where you can usually go short distances for more shotgun ammo.
