Former professional CS player Egor "flamie" Vasilyev spoke about the impact of crowd cues on match outcomes during LAN tournaments. He shared his personal experiences in a Telegram post.
"Regarding fan cues:
I’ve played in large arenas many times, and I can tell you that the noise of a massive crowd can be heard even through headsets and soundproofing. During a defuse or a flank, the shouts from fans often influence critical moments. This works both ways; it doesn’t matter which team the crowd is trying to support—when the entire stadium is shouting during a crucial moment, all ten players understand what’s happening. Sometimes players even turn around in response to the crowd’s shouts, just in case."
Earlier, a similar incident involving audience cues occurred during ESL Pro League Season 20, which was noted by Natus Vincere coach Andrey "B1ad3" Gorodensky during the final series.
