From publisher blurb:
Heavy Weapons is the second core sourcebook describing the Heavy Future Campaign Setting. Heavy Future detailed the world and its heroes, including a full gazateer, new races, feats, starting talents and class archetypes. Heavy Weapons provides new weapons and tactics for Heavy Heroes. Inside, you’ll find a dizzying assortment of truly nasty weapons, fucked up adventuring equipment, freaky new spells and magic items. Whether or not you need drugs, guns or money, you’ll find it somewhere in Heavy Weapons.
Heavy Future doesn’t directly contradict anything in any other Galaxy Command sourcebook, but radically changes the emphasis and redesigns the costume and visual tropes a little. The main difference between standard Galaxy Command and Heavy Future is emphasis- in bog-standard Galaxy Command, the Command are clearly the good guys. In Heavy Future, The Command are a bunch of prudish assholes. Which interpretation of events you prefer is your own choice, just know that you can use any other Galaxy Command supplements with this sourcebook.
Fully Compatible with the PFRPG.
