The player known as Ryut was caught in the TGS Signature Series Valorant tournament this past weekend. While he was competing on the team Tokyo, he was caught using some kind of aim hack during the livestream of the competition.
While moving near the area known as "Garage" on Haven, Ryut turned the corner and instantly locked on to the head of his enemy who was on the other side of the door. It was impossible for him to physically see the player, and the lock-on was a quick shot to the opponent's head. While a player may argue that they simply have excellent aim, this one was obviously a cheat.
The cheat was noticed during the quarterfinal match against Vancouver Elated, the team that beat Tokyo 2-0. Only the top four teams won prize money, but it's still concerning to see that someone was able to use a aimhack in a cash prize tournament like this. Riot's anti-cheat system known as Vanguard is great at detecting cheats, but it's certainly not perfect. It could take a while before new cheats are detected.
Ryut has not responded to the accusations and has apparently deleted all of their social media accounts, but a player who reported Ryut confirmed that they have been banned from Valorant. Most bans in the game are hardware bans, so banned players will have to get a new PC if they want to play again.
