McCallister said in response to my asking for ‘Bug World’ weapons—

Ummmm, you could have fly cruisers. Gnat personal transports. The outsider Moth-nectar collector teams. Spider-tanks. Beetle-class destroyers. Wasp pirate-vessel

====I’m not at all sure how you’d build a vehicle. Much less how you build an animal.

Also, these strengths and what not would have to be relative strengths since the spider is not on the correct scale for a typical setting.

For size measurements, a foot equals one millimeter in the Normal Human Scale.

But lets give it a try…

Character Name: Jack the Spider Tank Gender:Male Height: Ten feet Weight: Species:Spider

Persuasion (PER): 1@5
Charisma (CHA): 1@5
Animal Magnetism (ANMAG): 1@5
Strength (STR): 2@5 (Average insect str is going to start at 2@1 and go up to ants at 3@10)
Stamina (STA): 1@5
Resistance (RES): 1@4 (spiders are somewhat feeble here)
Density (DEN): 1@1
Flexibility (FLEX): 1@5
Agility (AGI): 1@5
Hand/Eye (H/E): 2@5
Intellect (INT): 0@5
Intuition (TUIT):1@5
Education Level (EDLEV): 1@2 (Basic commands known.)
Willpower (WP): 1@5

Pincer bite: 1@8
Leg Grab and Pin: 1@10
Dodge: 2@1
Wear Armor: 1@8
Understand Language: Bug People Pheromonal Language 1@5
Hold Platform Steady 1@5

Armor shifts attack down one damage level. Armor is made of chitin shell.

Catapult on howdah on top of spider. Catpult launchmaster is Bugfolk as are his two assistants. They require the spider to hold the platform steady in order to have any chance of success.
==============================More McCallister below…
For actual monsters you could have E.Coli(insert common bacteria name here), the Plague(octopi-looking viral/bacterium, a crossbread, it’s the age ol’enemy!), Colony010(monstrous looking failed attempts at the original idea), machinos(nanites from other experiments, usually benign but still deadly if you are caught while they are building something).

There would likely be some kind of schism between the outside frontier, and the inside lab, so maybe two factions.

Bug weapons:
claw-grapplers, stinkbug gland(jams transmissions), acid grenades, melee weapons, venoms, neuro-transmitter scramblers(or instinct reprogrammers), paralyzing jellies, webbing, mandibles, limb-blades, egg injectors, parasite injectors…
