An involved CYOA about a nuke going off that yields Fallout-style effects. Paths are deep and satisfyingly complex, varied, and the player character is competent. The storyline is a reasonable simulation of enduring the start of a nuclear post-apocalyptic wasteland (waving away some of the more clinical details associated with nuclear fallout).
The focus on gameplay coupled with the length and competence of the player character makes this a very interesting game well worth playing through. There are images that also enhance the atmosphere.
