A new The Callisto Protocol update has been rolled out today, adding the all-new Riot mode, new ways to kill, and the new Prospector Skin collection.

　　Developer Striking Distance Studios already announced the arrival of the update back in December of last year. Today's new update adds the new Riot mode in which players face hordes of biophage with each new phase becoming more difficult.  In this mode, players will also be earning credits to unlock powerful upgrades and purchase upgrades and health.

　　Also included with the Riot bundle are eleven new animations for Jacob showing lethal kills. These new kill animations are available in all game modes. The new patch also adds support for the new Prospector Skin collection which packs a new cosmetic set as well as weapons, and gear.

　　"Venture into a previously undiscovered area in the depths of Black Iron Prison filled with hordes of biophage in Riot Mode", the description of the new Riot mode reads. "Fight through increasingly difficult waves of enemies, earning credits to unlock powerful upgrades and purchase health and resources to help you survive. Complete objectives to unlock Rampage Mode, granting unlimited ammo and GRP charges that instantly kills enemies to give you the edge in battle."

　　The Callisto Protocol was released for PC, PlayStation 5, PlayStation 4, Xbox Series X|S, and Xbox One back in December of last year. Unfortunately, the game suffered from various performance issues, especially on PC. Since the game's release, various patches have been released that aim to address these apparent issues.

　　Here's what we wrote about the survival horror title from Dead Space co-creator Glen Schofield in our launch review:

　　"One area that The Callisto Protocol absolutely excels in, however, is in the overall presentation and graphical design", Kai Powell wrote in his review. "There's nary a single square inch of Callisto and Black Iron Prison that doesn't capture that derelict, abandoned spaceship vibes, complete with ambient sounds of creaking pipes or rustling footsteps in the far distance. Of all the technological advancements in the late 2200s, it's a surprise that aluminum soda cans are still the go-to staple for prison guards. The facial and motion capture are both among the highest of the industry standard, with both Karl Urban-lookalike Josh Duhamel and Karen Fukuhara (Kimiko from Darick Robertson's The Boys) looking exceeding close to their real-life counterparts thanks to the modified Unreal Engine 4 bringing The Callisto Protocol to life. The Callisto Protocol also features a Performance Mode on PlayStation 5 that felt almost essential to the experience. The tradeoff for slightly increased graphical fidelity and ray tracing simply isn't worth the performance drop from 60FPS which honestly felt like the game had frame pacing issues and overall sluggishness at the reduced framerates."
