A message from Cantis of the Red Veil Resistance:

Tenno,

You've helped the Red Veil in the past, now we want to return the favor. Our spies have discovered a large batch of Corpus Arctic Eximus are massing for training around the polar region of Mars. With so many Arctic Eximus gathered in one place, you have the perfect opportunity to strike a crippling blow against the Corpus field command.
Go to Mars and take out as many of the Arctic Eximus as possible. We will offer you what we can from the spoils.

- Cantis

HERE'S WHAT YOU'LL NEED TO DO
- Visit Mars and take out the specified amount of Arctic Eximus.
- Follow your individual progress bar to see how many Arctic Eximus you have defeated.
- Once you have fulfilled the objective, Cantis will contact you to congratulate you and provide you with your reward!

WHAT YOU NEED TO KNOW
- The Avalanche Offensive is on now until Monday, August 18 at 12 PM EDT.
- Once you have completed the Offensive, you can continue to assist your fellow Tenno in taking down the Arctic Eximus, however you will only receive one Reward.

REWARD
Successfully complete the Avalanche Offensive and you'll be rewarded with a 3-Day Affinity Booster.

Go forth and take down the Corpus Arctic Eximus, Tenno!
