Today, Valorant dev team uploaded an IG story video, with some screenshots and/or splash art hidden inside it. For me, it looks like they are teasing a new map, possibly something else. But on 1 specific screenshot, I think they are teasing a new Agent up close to his face. Judge yourself, but this could be huge with Act 2 coming up.
