Just Fudge it.
I have put together (another) Fudge conversion of Unknown Armies (1st edition).
You can get it from my homepage at www.schlaghund.de
The exact location of the file is http://www.schlaghund.de/main/files/fudge/repFu/UnknownFudge.pdf.
You will need Reptilian Fudge v2.0, which you can download for free as well.
Any remarks, comments and constructive criticism are welcome.
