The video in tweet, which you can check out further down this article, reveals very little. Hidden within it are cosmetics for Mirage, Pathfinder, and Wraith, and what appears to be a new energy weapon right at the end.
What the trailer itself doesn’t reveal, however, are any new characters. A voice that I initially thought might belong to a new Legend can be heard in the trailer, but as far as I can tell, it’s just the singer in the backing track. It could be that the lyric, which says “we ain’t gon’ never stop” relates to new character Octane, whose rumoured jump pads have started showing up in the game recently, but that’s purely speculative. Thankfully, more information has shown up elsewhere, confirming the battle royale’s first new addition.
