A League of Legends trailer was accidentally shown during the Brazilian Championship stream and—as we all know—once the genie is let out of the bottle, it’s impossible to get him to go back in. The trailer is quite good—showing a cinematic dominion battle on the Crystal Scar—but Riot never intended for the trailer to be shown.
Riot clarified things on reddit stating, “Hey guys, just a heads up, this was an unfinished prototype we ended up not moving forward with. Due to a small miscommunication associated with assets for the stream in Brazil it ended up being utilized unintentionally. Sorry for the confusion. Glad you thought it was cool though.”
