In Call of Duty: Modern Warfare 3 and Warzone, players can unlock free cosmetics through weekly challenges and in-game events. To earn more unique items, watch the Call of Duty League (CDL) Major 4 tournament on YouTube and earn free viewer rewards including emblems, calling cards, and a weapon blueprint.
Earn Free Tokens, Sprays, Cards & More! — CDL Viewership Rewards
To unlock the CDL Major 4 viewer rewards, you can watch the tournament live from June 27th through June 30th at 10:30am PT each day on the Call of Duty League YouTube channel. The broadcasts are already scheduled, so you can set up an alert to be notified when the match goes live. Before you do that, make sure your YouTube and Activision accounts are linked.
Once this is done, you’ll need to tune into the tournament or simply leave it running in the background when it goes live to unlock the free viewing rewards. Different prizes will be given to players depending on their viewing time on different days of the event; read more below.
The rewards are pretty cool, and CoD League fans who watch all the tournaments will unlock them anyway. If you’re only interested in a few of these cosmetics (say, the Play Your Life weapon blueprint), you can skip the Live on the other days and just watch the match on June 30th for two hours to get them.
