Is it possible for another player to DDoS me directly in Valorant?

Directly DDoS-ing another player *during* a Valorant match is unlikely due to Riot's server architecture and security measures. However, if a player obtains your IP address (through social engineering or other means outside of the game), they *could* attempt a DDoS attack on your home network. Riot actively works to prevent IP address leaks within the game.
