I Love It When a Campaign Comes Together...

Mary and I have been playing for three sessions now, and I have started to have an idea for a way to turn this into a campaign (and I'm thinking of it as a comic series as well). 

• In session one, our characters were sent to a gnat encampment to recover secret plans from the gnats. They were part of a large squad, but their helicopter was shot down en route and only these two survived. The gnats had recovered these plans (among other things) from a crashed fly helicopter. Our characters were successful in defeating the gnats and recovering the plans.
• In session two, they started to foot it back to the Hill (20 meters), but Mary's character remembered that there was a ladybug safe house only two meters away. They got to the safe house and found that it had been overcome by flies (looking for the plans that had been lost), and the few ladybugs stationed here were dead. They managed to recover a helicopter, and they decided to fly this back to the Hill.
• In session three, en route to the Hill, they received a distress call from some crickets who were under attack. These crickets were in a tower defending a bridge, but were under attack by three flea-controlled armored cars. Mary and I had our characters intervene, using the helicopter to provide air support, and defeating the fleas. It turned out the fleas had been infected in some way, driven crazy by something or someone. At the end of session three, they reported back to the Hill and turned over everything they found. Mary made her rank promotion check (I failed mine), and she improved to W-2 from W-1.

Going forward, I think I have the next three sessions planned... the 'plans' they recovered are for a mutagen that turns bugs into mindless, violent berserkers. Intel is going to reveal that the mutagen was created by a fly scientist. Our characters are going to be sent to board a train in transit and kidnap the scientist (session 4). This scientist will know of the hidden fly lab where they were working on this mutagen (session 5 and session 6). I already drew a map that was going to be part of my megadungeon for my fantasy games, but it's actually perfect as the hidden lab (the map is obviously unfinished, but I thought I'd give you a peak ahead). They're going to have to clear the lab out, defeating a whole bunch of insects that have been experimented on (and the flies doing the experimenting). The collapsed passage is to a lower level where the mutagen got into the air, and that whole level is filled with toxic gas (which will require the team to wear gas masks, and will change the 'feel' of the place). 

I think maybe the finale is an assault on an old castle controlled by a fly commander from 'the old days' who wants to return the flies to glory, and who financed the creation of the mutagen. Maybe the team will also have to defend the Hill from an attack by mutated insects... or maybe the mutagen is released in the Hill while they are away, and they have to try and neutralize their own friends and family with non-lethal attacks. That would be pretty cool, too. I'm happy for how this is coming together as a mini-campaign, and I think it would make a pretty good sourcebook at some point.
