From publisher blurb:
Sometimes, you just need to set someone on fire
... someone who's OVER THERE. Well, now you can with new flame weapons, and projectiles, shock, plasma, and more! 101 Ranged Weapons expands the armory of your Starfinder Roleplaying Game-compatible campaign with more than 100 new ranged weapons, from the mundane to the (slightly) magical!
Because you can never have too many ways to take down your foe without getting up close and personal.
