The Callisto Protocol v3.01 Update Adds New Game+: Full Patch Notes Listed

Striking Distance Studios

The Callisto Protocol has just received its latest update, and it's a big one.

Striking Distance Studios' sci-fi survival horror The Callisto Protocol launched in early December 2022. From the get-go, the game drew comparisons to 2008's Dead Space, as game director Glen Schofield was one of Dead Space's co-creators.

The Callisto Protocol drops players into the story of Jacob Lee, a contract freight transporter working for the United Jupiter Company. After ferrying shipments of unlabeled cargo between Europa and the UJC-operated Black Iron Prison on Callisto, his ship is boarded by the Outer Way — a terrorist group.

The ship is forced to crash onto Callisto. Lee is recovered by Black Iron Prison security head Captain Leon Ferris and committed to Black Iron Prison without charges. Jacob soon finds himself, and the prison, in the midst of being overrun by inmates infected by "biophages."

Reception to the game was mixed, with some citing its unique combat as a hang-up point alongside a number of bugs. But, the studio was quick to roll out updates to improve optimization, squashing a number of issues out of the game for good. And it seems the updates didn't stop there.

As of yesterday, Jan. 19, The Callisto Protocol received its v3.01 update which added in New Game+ alongside additional fixes.
