In Chronochaos, players assume the role of Jett Echo, a lazy librarian who inadvertently discovers a time-traveling artifact hidden in the library's archives. Unfortunately, using it haphazardly causes chaotic time ripples, pulling historical figures, absurd creatures, and even future tech into the present. Players navigate various comedic situations as they try to fix the timeline, interact with misfit characters ranging from a grumpy Viking to a wisecracking AI, and engage in time-bending puzzles. Choices affect both humor and the timeline, leading to outrageous consequences that can alter history forever.
