MOD 1 – RAPID FIRE: HOLD FIRE to fire your semi-automatic weapon at maximum speed.
Rapid Fire will slow down your fully automatic weapon.
MOD 2 – STEADY FIRE: HOLD FIRE to fire your weapon at a steady pace with a delay between shots to improve accuracy.
This works best if your weapon deals enough heavy damage on impact to afford firing it more slowly. This is typically a trait of assault rifles.
To change Steady Fire to the more advanced Dynamic Mode, please see the STEADY FIRE MODE section.
MOD 3 – BURST FIRE: HOLD FIRE to repeatedly fire your weapon in bursts to improve accuracy.
This works best if your weapon deals most of its damage due to its fast rate of fire. This is typically a trait of submachine guns (SMG).
MOD 4 – AUTO BURST FIRE: HOLD FIRE to repeatedly fire your fully automatic weapon in bursts to improve accuracy.
This MOD has a better fire rate with your fully automatic weapon but you will have to RAPIDLY TAP FIRE yourself for your semi-automatic weapon.
