From legendary game creator Hideo Kojima comes a genre-defying experience, now expanded in this definitive DIRECTOR’S CUT.

In the future, a mysterious event known as the Death Stranding has opened a doorway between the living and the dead, leading to grotesque creatures from the afterlife roaming the fallen world marred by a desolate society.

As Sam Bridges, your mission is to deliver hope to humanity by connecting the last survivors of a decimated America.

Can you reunite the shattered world, one step at a time?

DEATH STRANDING DIRECTOR’S CUT on PC includes HIGH FRAME RATE, PHOTO MODE and ULTRA-WIDE MONITOR SUPPORT. Also includes cross-over content from Valve Corporation’s HALF-LIFE series and CD Projekt Red’s Cyberpunk 2077. Stay connected with players around the globe with the Social Strand System™.
