Amazon and Super Evil Megacorp are doing things a bit differently this season. Starting today until September 11th, the top eight teams in North America and Europe will be facing each other every weekend. The Appstore will reward players with discounts and Amazon Coins throughout the tournament. By the end of the season, the e-retailer will host a huge championship event. It's not clear at this point where it's going to be held, but you can watch Twitch's coverage of the tournament on the official Vainglory channel.
