I think we can all probably agree it was a tenuous tie-in in the first place, unless after release an updated PUBG set on Jupiter's moon of Callisto came into the fray, which honestly in even typing that seems like a massive reach.

And so here we are with The Callisto Protocol from Dead Space co-creator, Glen Schofield, now standing on its own merits and set to release sometime this year.

FYI @CallistoTheGame is its own story and world. It no longer takes place in the PUBG Universe. It was originally part of the PUBG timeline, but grew into its own world. PUBG is awesome, &we will still have little surprises for fans, but TCP is its own world, story and universe.

As per an interview with Schofield in Game Informer and from the Tweet above, the development heavyweight has now revealed that the game became too big and too "out there" to be able to have any official ties to PUBG, from a shared universe perspective. Though some of the planned links will remain in the game as Easter Eggs, the creative director revealed.

"When we came in, they had a lore team and they were writing this big story, like, ‘Where does PUBG start? Where does it fit in?’," Schofield said. "They write this giant timeline and our writers are involved in helping. We sit on the timeline, but we sit pretty far out there, and kind of alone. So if they ever make another game, let’s say that’s after our timeline. I would imagine our game will inform that more than we are being informed by their timeline."

Given the game is Game Informer's June cover it's safe to say everything is on track for The Callisto Protocol to launch this year, as promised, and with all the Dead Space Remake hype around, it couldn't have been orbiting a better opportunity from a hype and player-want perspective.

We'll have more on the game as it becomes available.
