About the Game



Norrune, the city of oil rigs, is ravaged by the terrorist activities of the mysterious Scorch who is set on dismantling the foundations of civil society. Calico - along with his fellow N.P.D. officers - must do everything in their power to battle the onslaught of crime plaguing their home.

Combustion is a pulp noir story inspired by classic games, films, and comics of the late 80s and 90s. Heavy combustion engines, CRTs, and rustbucket robots are all part of this game’s gritty dieselpunk setting.



  • Engage in police work and solve the case of the vicious serial-killer Scorch.
  • Explore the city of Norrune between missions. Visit its many streets, shops and even the amusement park.
  • Enjoy a content rich Action RPG. Set perks before any mission and be rewarded for engaging with a detailed and reactive game world.
  • Use Calico's special baton with a built-in lasso, freeze-spray, electrical stunner and much more.
