Contagion Survival Guide
A weapons and tactics manual for Contagion Second Edition, presented partly through the writings of a veteran arms dealer who prepares humans to face the supernatural. It includes game statistics and descriptions for over 100 firearms, along with archaic, missile, exotic, non-lethal, and improvised weapons. The guide also expands armor and wearable gear options, adds lists of edible and poisonous plants, and introduces systems for weapon recoil and randomized hit locations. Its rumors, tactics, and weapon accounts are presented from a character’s perspective and may not always be reliable.
