Maybe, MAYBE, these things can be dog/horse sized? Nice and managable? The bigger ones, the siege bugs or the general bugs or the kings or the wasp-stinger-artillery, THAT can be big. But not the grunts.This shit ain't writ but it's NEUTRAL, goddamn. Quit writing the dude's setting for him. He came here asking about weapons.Weapon choice, you're all retarded. Have the exo-skeleton be tough enough to make punching useless. THAT'S ALL. These things HAVE to be able to be taken down by small groups, because the OP hasn't made it clear what his campaign is about. Assume it's a small party, because that's the most likely; if he wants squad-based or grand-strategy against bugs, there are systems he can imput that into. But it's more likely, given the range of systems, that it's a small party. So that's gonna prey on these bugs, so that's what they should be vulnerable to. Not 20-man formations, not immobile siege batteries. Small men, who drink ale, whore around, and travel in bro-groups. If the OP wants bigger, he can make it bigger, but it doesn't help him if you all say 'COUNTER-SWARM'. Start it small, he can work up.2/10 thread guys, and that's generous. This guy came to /tg/ for help, he deserves better.Any misspelling is the MAD talking.
