The Shadowfrost Armor Style in Halo: Campaign Evolved comes from a limited UNiDAYS Xbox promotion. Eligible students can claim the offer through UNiDAYS, redeem the promotional code on Halo Waypoint, and then equip Shadowfrost from the game’s Customization menu.
The promotion is currently scheduled to end on August 16, 2026, so there is not much time left to grab it.
How to Get the Shadowfrost Armor Style
To unlock Shadowfrost, claim the Halo: Campaign Evolved Master Chief Armor offer through UNiDAYS and redeem the promotional code on Halo Waypoint.
Here are the full steps:
- Sign in to your verified UNiDAYS account.
- Find the Xbox offer labeled Get a Master Chief Armor.
- Select Get now and claim the Shadowfrost promotion.
- Copy the promotional code provided through the offer.
- Sign in to Halo Waypoint with the Microsoft account linked to Halo: Campaign Evolved.
- Open the Halo Waypoint Code Redemption page.
- Enter the promotional code and redeem it.
- Launch Halo: Campaign Evolved.
- Open Customization from the main menu.
- Select Armor and equip Shadowfrost.
Make sure you redeem the code on the correct Microsoft account. The cosmetic is tied to the account used on Halo Waypoint.
Do You Need a UNiDAYS Account?
Yes. Shadowfrost is a UNiDAYS student promotion rather than a universal Halo code that anyone can copy.
UNiDAYS may verify eligible students by sending a verification code to an academic email address. In my case, an older college email with the school’s domain was enough to complete verification, and no student ID or additional documentation was required.
Verification options can vary by school or account, so some users may see a different process. Once your UNiDAYS account is verified, you can claim the Halo: Campaign Evolved Shadowfrost offer and redeem the promotional code through Halo Waypoint.
How to Equip Shadowfrost
After the code has been successfully redeemed, launch Halo: Campaign Evolved and open Customization from the main menu.
Select Armor, locate Shadowfrost, and equip the style. If it does not appear immediately, restart the game and confirm you redeemed the code using the same Microsoft account connected to your copy of Halo.
Shadowfrost is a much shorter opportunity. Claim the UNiDAYS offer before August 16 if you are eligible, because this particular frozen Chief is about to thaw out of the freebie rotation.
