After multiple super confusing trailers, it looks like Kojima is dishing more on his mysterious game, Death Stranding. In a new interview with IGN, Kojima reveals tons of cool lore and gameplay details... like the fact that the underwater sequence seen in the most recent trailer is actually the game over screen?
Yeah, apparently so. Kojima says when you die, death isn't the end. Rather, you hang out in that purgatory type space and can collect items or go back to your body, during a countdown timer. Once you go back, the game doesn't reset you to before the point you died -- you pick back up in the game world. He also commented on the rain that seems to age people -- it's apparently called Timefall and it's super important to the story and lore. And if you're wondering where this new trailer falls in with the actual game, Kojima revealed that it's pretty close to the game's prologue, and happens fairly early on.
So yeah... maybe that'll make Death Stranding make some more sense for you. Or not. There's actually plenty more to read about in the IGN interview, and I highly recommend giving it a read -- it also goes into Kojima's love for fan theories, and some of the struggles they went through because of the recent voice actor's strike.
