Just prior to the start of Gamescom 2018, Activision announced The Collector's Edition for From Software's Sekiro: Shadows Die Twice. The Collector's Edition will release alongside the normal version on March 22, 2019.

"We can't wait for fans to finally get their hands on Sekiro: Shadows Die Twice," said Steve Young, chief revenue officer at Activision. "Fans will get a taste of the multiple tools available for the prosthetic shinobi arm this week at Gamescom, and will be able to fully dive into the brutal, dark world of 1500s Sengoku Japan when the game launches [this March]."
