WHAT WORKS: Well, it's all completely optional, but this and the main book gives you almost a complete replacement for the After the Bomb RPG with better rules for $5. The mutations are divided between "sensible" and "completely crazy", depending on your tastes...and humanoid plants are included. And charts. Random charts.
WHAT DOESN'T WORK: If you didn't care for Atomic Highway, this isn't going to be much use to you.
CONCLUSION: Was Atomic Highway too "safe" for you? This will completely blow it up. It's completely optional, in no way invalidates anything in the assumed Atomic Highway setting and can even take a lot of the guesswork out of it for you with the random roll charts. Do you need it? No...but it sure does up the zany fun factor playing a mutant humanoid Venus Flytrap Bounty Hunter that can burn things with his mind.
