Valorant Agent 15 is expected to arrive in Episode 2: Act 2. Here's everything we know so far based off the details Riot Games has revealed.
Valorant Agent 15: Everything We Know So Far
To start off, we know this new agent will be a controller, officially being the fourth one added to the game. Currently, Viper, Omen, and Brimstone are the only controllers in the game, so getting some variety in the role is refreshing. It also makes sense from a balance perspective, as since the beta, every other role has received a new agent already (Reyna for Duelist, Killjoy for Sentinel, and Skye for Initiator), so it's about time for controllers to get another addition.
Apparently, this new agent will "push the boundaries" of the game and will serve as a "cosmic shift from the play patterns you've grown accustomed to", so it's likely the new agent will feel completely different and unique from the others. However, Riot mentioned the new agent will be for players that like to study everything occurring on a map, so it's possible this agent's toolkit revolves around positioning and using the quirks of each map to their advantage.
Episode 2: Act 1 of Valorant ends March 1, so expect Episode 2: Act 2 to drop soon after.
