I'm getting tired of this. I'll just spill the beans on the Bug story. :|
Some time in the year 2013, nuclear power gets really poplar. So much so that the humans have to find a way to dispose of all the extra nuclear waste . They tried several things, but eventually decide to just put it all deep in the earth. Then three years later (2016) an unexpected meteor storm began smashing earth with millions of watermelon-sized meteorites,causing earthquakes. Thinking their underground home was being threatened, millions of bugs, all mutated from the nuclear waste, headed strait for the surface.
And there you have it! (mostly) This is only the Bug story though, NOT the RPG story.
:D
