The Callisto Protocol Update 1.18 Dices Out for May 23 (Update)

The Callisto Protocol Update 1.25

Riot mode, the survival-based game mode, is now available for The Callisto Protocol as part of update 1.18. Read on to learn everything included in The Callisto Protocol update 1.16 patch notes.

The Callisto Protocol Update 1.18 Patch Notes for May 23:

Update: We’ve added the official details for Riot Mode straight from Striking Distance.

Survival Basics for Riot Mode: 

Jacob Lee finds himself in an isolated corner of the prison, just three rooms and connecting hallways that contain loot crates full of health gel packs, health injectors, GRP batteries, and ammunition. Armed with the stun baton, GRP, a hand cannon, and a riot gun to start, Jacob must defend himself from endless waves of biophage enemies who vary in strength and composition. The longer he survives the more he will be hunted, with increasingly vicious foes, such as the Two-Head, appearing over time.  

Unique to Riot is Rampage Mode, a new gameplay modifier that players can activate by scoring points and filling up a meter. Rampage Mode grants a short period of infinite ammo and GRP charges, and enemies will die from a single attack.  

Riot Mode’s Scoring System: 

Success in Riot Mode is measured through a scoring system that awards points for kills based on weapon used, enemy limbs severed, and types of enemies defeated. At the end of every Riot Mode run, players are given a final score that they can compare against other players. Success in Riot Mode also awards medals based on how long you survive and how many points you earn. 


As of right now, we only know that this update includes Riot Mode, a new survival wave-based game mode that pits players against hordes of enemies as they try to rack up the high score and compete against others with the online leaderboards. There are a couple of new cosmetics also included in this update.

As always, we’ll be sure to monitor all community feedback, and will update this post as more gets discovered, or whenever Striking Distance finally releases the full patch notes.
