Ich hab selber auch noch keinen Blick drauf werfen können aber rein von der Beschreibung/den Infos die ich habe wird es kein Rundumschlag sondern ein dediziertes Waffenbuch.
Run And Gun (Core Rulebook): Guns and ammo cost nuyen. Mastering martial arts takes time. And learning how to use explosives without blowing yourself up takes patience and a steady hand. These weapons and more are out there, waiting for you. You have the chance to use them to become deadlier, faster, more dangerous than the next guy—and more dangerous than you were yesterday. You’ll have to pay the price to get what you want, but this is the Sixth World. Don’t you always? Run and Gun is a combat core rulebook for Shadowrun, Fifth Edition, containing more weapons, more armor, more modifications, and more game options such as martial arts and unit tactics. Break the book open and prepare to raise your game.
@PDF-only/Sammelbände: Hab ich bisher nichts zu gehört, ich gehe aber davon aus, dass sowas geplant ist. Das ist aber wie gesagt nur eine Vermutung meinerseits.
