Monster rounds for depush / pushing / farming
Only buy Swift Striker if you feel like you need it early, otherwise rush Burst Fire.

Building more into bullet shred and gun damage.

Pick an armor type to counter enemy damage
Can opt to sell Battle Vest, Slowing Bullets, or Bullet Lifesteal
Substitute Crippling Headshot for Armor Piercing Rounds if you are against a Viscous / Yamato.
