After more than six years of near-total silence, BioShock 4 is finally making noise again. New leaks from MP1st have dropped some tantalizing details about the long-awaited sequel, including a casino setting, mysterious new enemies called Flushers, and renewed hints about that Antarctic location we’ve been hearing whispers about since 2021.
The BioShock franchise has been on ice since 2013’s Infinite, and fans have been desperately clinging to every scrap of information they can find. Despite a troubled development cycle that’s seen leadership shake-ups and failed internal reviews, these latest leaks suggest the game is still very much alive and potentially taking shape in interesting ways.
Casino Center Stage
According to sources speaking with MP1st, a casino will serve as a prominent location in BioShock 4. This isn’t just a quick pit stop either – the casino is described as potentially being grander in scale than previous BioShock locations and could serve as the stage for a major set-piece battle. Think Big Daddy encounters but with the glitz and glamour of a retrofuturistic gambling hall.
The leak also mentions a district called Solaria or Solaris, though the exact nature of this location remains unclear. Solarians could be controlling elites, everyday citizens, or even an enemy faction depending on how Cloud Chamber decides to structure the game’s world. The name certainly evokes sun imagery, which creates an interesting contrast with the snowy Antarctic setting that keeps popping up in rumors.
Meet the Flushers
Every BioShock game needs its twisted foot soldiers, and BioShock 4 appears to be introducing enemies known as Flushers. While specific details are scarce, the name alone sparks curiosity. In the original BioShock, we had Splicers – ADAM-addicted residents of Rapture who became violent and deformed. The leaks suggest an ADAM-like substance is making a comeback, so having a Splicer equivalent makes perfect sense for the series continuity.
The term Flusher could refer to how these enemies extract or process this mysterious substance from their victims, similar to how bodily fluids are flushed from the system. It’s a grotesque concept that fits right into BioShock’s wheelhouse of body horror and scientific hubris gone wrong.
Antarctica Still in Play
Back in 2021, YouTuber Colin Moriarty claimed BioShock 4 would take place in a 1960s Antarctic city called Borealis under the codename Parkside. These new leaks from MP1st reinforce that snowy environments will play a significant role in the game’s atmosphere. The idea of a secret scientific city buried in the frozen wastes of Antarctica fits perfectly with BioShock’s tradition of isolated utopian societies that inevitably collapse into chaos.
A leaked screenshot from 2021 showed a retro-futuristic tower with a glowing orb on top – the classic lighthouse motif that’s been central to every BioShock game. There’s always a lighthouse, after all. The combination of Art Deco design sensibilities with icy Antarctic landscapes could create some truly stunning visual environments.
Character Models Surface
The leaks include assets showing what might be the game’s antagonist and protagonist. Golden statues with highly detailed faces suggest a villain in the vein of Andrew Ryan or Comstock – larger-than-life figures who built these impossible cities based on radical philosophies. Meanwhile, a human figure used for environmental scaling purposes might hint at the protagonist’s design, though it could just as easily be a placeholder or random NPC model.
Development Remains Rocky
Let’s be real – BioShock 4’s journey has been anything but smooth. The game was first confirmed back in 2019 when 2K announced new studio Cloud Chamber would handle development. But according to reports, this version of BioShock 4 has actually been in the works since 2017, and there was an even earlier iteration at Certain Affinity that got cancelled in 2016.
Things took a turn for the worse in mid-2025 when Bloomberg reported the game failed an internal review by 2K executives. Studio head Kelley Gilmore was removed, creative director Hogarth de la Plante shifted to a publishing role, and the narrative was flagged as needing a major overhaul. Layoffs hit Cloud Chamber in August 2025, and analysts now expect the game won’t launch before 2027 at the earliest.
Despite all this chaos, Take-Two CEO Strauss Zelnick has repeatedly assured fans the game will release. During an August 2025 interview, he stated definitively that BioShock 4 is going to come out, hand on heart, without question. Whether that confidence is justified remains to be seen, but at least the game hasn’t been cancelled outright.
What This Means for Fans
These leaks represent the most substantial information dump we’ve gotten about BioShock 4 in years. The casino setting, Flushers enemies, and Antarctic location paint a picture of a game that’s trying to honor the series’ legacy while carving out new territory. BioShock has always been about exploring failed utopias and the dangerous ideologies that created them, and a frozen research city with a gambling district sounds like fertile ground for that kind of storytelling.
The return of an ADAM-like substance suggests Cloud Chamber isn’t abandoning the series’ core gameplay loop of genetic modification and moral choices. And if the leaked screenshot is legitimate, we might see mechanics involving magnetic powers, electrical abilities, and time manipulation – all classic BioShock fare with potential new twists.
Of course, given how much the game has changed during development, anything from these leaks could be outdated or scrapped entirely. The screenshot dates back to 2021, and we know the narrative has undergone significant revisions since then. Still, for fans who’ve been starving for any BioShock 4 news, these leaks offer hope that the game is real, it’s progressing, and it might actually deliver something special whenever it finally arrives.
