The Callisto Protocol's latest update adds Hardcore Mode and ray tracing optimisations and more

The Callisto Protocol has gotten more hardcore with the game’s latest update

The Callisto Protocol has recieved another major update, an 11GB patch that adds a new “Hardcore Mode” to the game alongside a new set of bug fixes and performance optimisations. 

On PC, The Callisto protocol’s latest update is said to deliver ray tracing performance improvements, enabling higher framerates for gamers with compatible hardware. That said, The Callisto Protocol’s PC version remains very CPU limited when ray tracing is enabled, which limits the impact of these performance gains.

With Hardcore Mode, The Callisto Protocol’s difficulty is increased by reducing the number of ammo, health, and credit drops from defeated enemies, increasing enemy damage, decreasing stun baton damage, and increasing enemy mutation speed. A Hardcore New Game+ mode had also been added, which requires a finished playthrough of the game’s Hardcore mode to access. Alongside this mode, new achievements and trophies have also been added to The Callisto Protocol on all platforms.
