Where can I find the "User ID" to fill out in the survey for participants of the Global Beta Test "Deadly Playtest"?

Launch the game > Your "User ID" will be listed in the bottom right of the "Title Screen."
Please take a moment to enter this ID into the survey form.

Alternatively, while playing the game, you can open the Menu (≡) to check your "User ID" which will be displayed underneath your player name.
