Smoke Attack is an arcade-style, top-down shooter originally released in 2002 as a freeware promotional game commissioned by the Swiss Federal Office of Public Health. The game follows "Oxy," a jetpack-equipped hero tasked with neutralizing aggressive, cigarette-smoking creatures to clear the air in various office environments.

Released in 2004, the sequel Smoke Attack 2 retains the core mechanics of the original but introduces new stages, smarter hazards, and improved graphical polish. While similar in gameplay, it is often described as an expanded level pack for fans of the first title. Smoke Attack 2 - Kotaku
