Twitch Prime: Get Two Wrecking Ball Loot Boxes
Twitch Prime members can now redeem two Wrecking Ball loot boxes for free. Come back to redeem one Golden Loot Box on September, then again on October. Sweet. Click on the Wrecking Ball banner at the following page.
The content of each loot box is random, and do not include seasonal event loot. You can claim this free loot box until September 3, 2018, and boxes can be opened the latest by December 31. Below you can see two loot boxes I opened from this Wrecking Ball offer.
