From publisher blurb:
What you’ll find in the Hypercorps 2099 Wasteland: Primer:
Radraider Primal Path - An archetype for barbarians that do not fear radiation but wield it instead, using their rage to turn atomic energy on their foes!
Wasteland Character Backgrounds - Play as an alien abductee from the past, a lucky escapee from an underground shelter, or a captain from an underground shelter that’s decided the Wasteland offers a brighter future.
Wasteland Gear - In order to survive the irradiated landscape you’ll want a geiger counter, some iodine pills, and if you can afford it, a lead-lined backpack to keep your food from becoming poisonous.
Wasteland Skills - You can’t say “mad science” without “science” and you can’t adventure in the Wasteland without a nod to Technology!
Radiation and Irradiated - Radiation is a vital element of Hypercorps 2099 Wasteland and the rules for atomic energy are included with a new attribute for once you’ve gathered up too much of the stuff in your cells.
Wasteland Monsters - Brain slugs to take over your mind with the slug-brained template, an irradiated bear (via another template!) because those are just too tough to die out, the dreaded purple people eater, and zombie-like walkers (including short rules for the smart walker player race)!
Hypercorps 2099 (5E) is not required for exploring the Wasteland and this is a standalone supplement.
