During event matches, you will get special bonuses when using certain pieces of gear, or specific weapons. If you have a boosted weapon/gear equipped, and you aren't receiving their event bonus, the first thing is to double check what each bonus grants you, as well as if you have a boosted weapon/gear equipped:
Weapon Bonus:
Using the correct type of weapon during an event will increase the SCORE you gain at the end of the match.
You can see which weapons are boosted (and by how much) by clicking on the EVENT RULES tab:
Gear Bonus:
Using the correct type of gear during an event will increase the DAMAGE of your weapon.
*The gear bonus does NOT impact the points received at the end of a match.
*The gear bonus is currently NOT available for Head Hunter events.
