Read the Thrillbilly Mud Club watermark in GTA 6

A social-video-style shot puts a name to the mud party in Trailer 1.

Pause around 0:55 and look in the bottom-right corner. The Thrillbilly Mud Club name is embedded in the shot itself, the same way a club might brand a clip on a real social feed.

It is a clue to the people and activities away from Vice City’s beachfront. Save the mudding footage as a reference if you want to compare vehicles and locations once public gameplay is available.
