This collection of adventures ought to get your campaign off to a flying start. The first adventure, in particular, is designed to be an introductory one - for both new characters and new players alike - giving a good snapshot of the state of the world and what one needs to do to survive and prosper in it. A simple task, to get weapons and tools believed to be stored in the remote home of a gun enthusiast who hand-loaded his own ammunition, gives opportunity for wilderness travel and encounters as well as building relationships for the future. Neat!
The following three adventures introduce other typical aspects of post-apocalypse life such as warlords, environmental contamination, recovery of information and the like... all presented beautifully in context, in adventures that bring this alternate reality to life. As the tales progress, the feeling that this might well be what life after a nuclear war might be like becomes strong, a believable setting in which to develop your characters and your campaign.
Anyone who enjoys post-apocalypse games should find this worth a look, even if they don't play Surviors of The Fire but use a different ruleset - you may need to tweak a few stat blocks but most will be useable.
