The Callisto Protocol Update 1.019 Patch Notes | The Callisto Protocol May 23 Patch Notes

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, Striking Distance has yet to post any official patch notes for update 1.019. However, as we know from an announcement made earlier this month, this update introduces the all-new riot mode to the game. Additionally, players will also notice some new weapons and character skins included in this update.

What is Riot Mode?

As revealed on the Xbox News Blog: Riot Mode features enemy behavior and wave composition that keep players on their toes. As you progress through the game, you’ll need to adapt your strategies to overcome each new challenge. With only two weapon slots available, you’ll also need to spend credits wisely to upgrade and change weapons and to open health, GRP, and fuse containers. And when things get really tough, activate rampage mode for a temporary buff with unlimited ammo, GRP usage, and enemy insta-kill.

Once Striking Distance has released the full patch notes, we’ll be sure to update this post. For now, go an enjoy the new riot mode!
