In an interview with entertainment website Leo a few days ago, Norman Reedus casually announced that he's begun working on a sequel to Death Stranding. The interview was promoting Reedus' upcoming novel and mostly focused on that and his upcoming Walking Dead spinoff, with only a little attention given to his video game work. But when the interviewer prompts Reedus to talk about Death Stranding, he blurts out "We just started the second one."
The sequel isn't discussed any further, as they instead delve into how Reedus first became involved with Kojima (through their mutual collaborator Guillermo del Toro) and the process of filming for a video game. "It took me maybe two or three years to finish all the MoCap sessions and everything. It takes a lot of work. And then the game came out, and it just won all these awards, and it was a huge thing," says Reedus, before casually adding again, "so we just started part two of that."
Given the casual nature of the reveal and lack of details, it's possible Reedus didn't know this hadn't already been announced, or was simply slipping it in to help draw attention to an interview focused on his novel. Either way, that seems to be all the information we'll be getting for now and, if Reedus' estimation of "two or three years" to film the game is accurate, it's likely we won't be seeing Death Stranding 2 any time soon.
