With Xbox now handling publishing for Hideo Kojima’s new project PHYSINT, the question of which platforms the game will actually launch on has become a new mystery. In a recent interview, Kojima admitted that it’s still unclear whether the game will even come to PlayStation. The project originally had close ties with PlayStation, but now that the partnership direction has shifted, platform plans haven’t been finalized either.
Setting Aside the Familiar Old Partner
Another question players are focused on is whether PHYSINT will continue using the Decima engine developed by Sony’s Guerrilla Games. Kojima stated that the team is still in the experimentation phase and hasn’t decided on the final engine — however, he hopes to leverage Xbox’s technology as much as possible. In other words, the technical partnership built through the Death Stranding series won’t necessarily carry over unchanged to the new project.

From PlayStation to Xbox — Does Development Direction Need Rethinking Too?
Kojima Productions was previously developing PHYSINT with Sony, but after Sony stepped out, Xbox took over publishing. This change isn’t just about switching publishers — it also brings platform and technical support arrangements back to the table. Kojima hasn’t confirmed whether the game will come to PlayStation or announced the final engine, so for now, it’s too early to definitively label it as an Xbox exclusive.

The Answers Players Most Want to Know: Still Unknown
PHYSINT still has many key details undecided, including platforms and engine choices. Kojima mentioned he hopes to make good use of Xbox technology, but that doesn’t mean Decima has been definitively abandoned. For players, what changes this partnership shift will bring remains to be seen — we’ll have to wait for more updates from Kojima Productions.
