During the surge of anime collaborations with games, PUBG Mobile has announced their collaboration with Higurashi: When They Cry - SOTSU in Japan to promote the anime series.

Players in Japan who log in between September 30 and October 28 will receive a sample voice card from Higurashi: When They Cry - SOTSU, as well as a Traveler Ticket, which can be used to open crates containing cooperation products on the second day. Ryugu also comes with a challenge letter that states that if you defeat an opponent with a melee weapon, you will win a Traveler Ticket. This challenge will last until October 14th.
