Tornado Shack

You and your group decide to start going through Grampa E. Budwick's old tool shack on the farm when a storm hits from know where. Things start flying and winds start shacking and throwing stuff up against the old shack. This shack will not hold for long so you and your group must free the debris against the shack and make it to the bunker outside before its too late. The storm is getting worse with high winds and rain. The Tornado is approaching fast so time is of the essence to get to the bunker for safety.
