Last Vestige of Hope

From publisher blurb:

Last Vestige of Hope is an adventure for 4 to 6 low-level characters that are just starting their initial ex-plorations of the ravaged wastelands within a devastated Earth. It is a story of desperation, daring, and ultimately, at its conclusion, great achievement. It pits the characters against despicable humans and hungry, non-human foes for the first time. Although this adventure could be dropped into any existing campaign, it is ideal for newly created characters who are leaving (willingly or forcefully) the safety of their settlement for the very first time.

This adventure was designed for use with first edition Gamma World but can be adapted to any post-apocalyptic roleplaying game.
