For reference, the entire tier rewards list can be seen below, as well as how to participate.

Tier 1: Emblem “Clip”

Tier 2: Calling Card “Eagle Gunner”

Tier 3: Weapon Charm “Bang!”

Tier 4: Special Helmet “M1 Ammo Reserves”

Tier 5: Grease Gun “Rosie II” (75 million Contracts and Orders)

Event Start Date: Friday, April 20, 2018

Event End Date: Tuesday, May 8, 2018

Here’s how to participate:

Log in on April 20 and start completing Contracts and/or Orders. Complete as many as you can! After each Tier is completed by the community, all eligible players will receive that Tier’s reward. Note: If you log in on April 20, you’ll be eligible to collect the rewards from all Tiers. However, if you don’t log in during Tier 1 and log in after any given Tier has been completed, you will only be eligible to collect the rewards for each subsequent Tier. For example, if you don’t log in between April 20 and the time Tier 1 has been completed, but log in during Tier 2, you will only be eligible to receive the rewards from Tiers 2-5.
