From publisher blurb:
A tornado is a violently rotating column of air that extends from a thundercloud to the ground. Also called twisters, whirlwinds, or cyclones, a tornado is the most violent and unpredictable atmospheric disturbance. They’re also among the most recognizable
A tornado is also a dangerous, implacable, invincible foe that makes even the doughtiest adventurer quake in terror. Guns are useless against it, reason can’t sway it, and even the mightiest of starships is forced to flee from its horrific power.
Hazard: Tornado! allows the Referee to bring this awesome force of nature into the campaign. This short file is packed with a (vastly simplified) discussion of how tornadoes form, their characteristics, game stats, and what happens to those who dare stand against one.
Hazard: Tornado! By the time you see it, it’s already too late.
