ijed gives us some Quake fan fiction over at Quaddicted. Here's a snippet:
The individuals that made up the group couldn't even be called as such. They were grown in vats, more than half their brains being composed of circuitry. They communicated by short wave radio, but not with anything as primitive as speech. Instead it seemed to be directly by thought. So far human technology was yet to properly crack open either telepathy or cloning. Interesting stuff indeed.
It's a short read so there's no reason to head over to Quaddicted and read the whole thing!
