You can get a free lootbox if you watch 1 hour of those who have OWCS drops active. As well as other OWCS cosmetics.
Emongg, ML7, and August have them available as of right now. Or you can get them from the official OW_esports channels when they go live.
This is one of three events that are each a day long so you can only obtain these items within a 24 hour period for each event! April 18-20
Thank you very much for the reminder I would have forgotten about this 
That is not enough of a bribe to sit through 15 minutes of twitch ads.
Is anyone having issues of the lootbox not showing in game? I watched for one hour, claimed the lootbox but it is not there.
Just keep it open in another tab and mute the tab then, it’s only an hour you have to have it open to earn one
Give it time, sometimes it doesn’t immediately show up for a while. This happens with drops.
You aren’t going to watch the program…why are you worried about the ads…
