I'm pretty sure I've banged on about this before, but I've made an effort to include more alien races in Psi-Wars (there will be a post on that soon) and I've been exploring the alternate tech of alien groups like the Ranathim Tyranny and the Mug Atheocracy, which has emphasized the need to explore guns, and my own research has begun to finally bear some fruit. As a result I've found myself confronted with the core issues with the Guns of Psi-Wars. I'm sure I've discussed this before, but there's new material before, so I apologize if this comes across as repetitive.
So, let's start with does Psi-Wars need guns? I think it does, and it needs them in the same way that settings it draws inspiration from all have guns too, despite having access to other, better weapon. Star Wars has projectile rifles despite having blasters; 40k has slug throwers despite having micromissile "bolt" guns; Dune has Maula pistols despite having lasguns. These weapons tend to be either niche weapons meant to get around a particular problem, or they're primitive weapons used by factions that lack access to better weapons. I particularly want to explore the latter, because the world of clean blasters and elegant, carbide armor is the Valorian Empire and the Galactic Alliance, not the world of post-apocalyptic techno-savages or primitive aliens. Guns also allow us to deliver warheads down range. Psi-Wars definitely has guns in a strictly literal sense in the form of grenade launchers, and weapons that fire poison darts certainly fits some factions well.
So, if we have a need for guns, how do we design them, and how do we make them fit? These two questions have plagued me, but I think I finally have some answers.
