I have seen it. The death camp bit is a fairly insignificant in size compared to the bulk of the book. About half a page. I can post a scan or type out the text of the page in question if mods/fair use allow it.
Basically there's a column or so on how horribly haunted and dangerous Shadowrun-Auschwitz is, and there's a short adventure suggestion/plot hook that has basically no detail at all regarding plot, enemies (though given the site writeup, the only possible opposition here is the spirits of the murdered death camp victims), location layout etc, and boils down to the PCs going into Auschwitz to recover the scalpel of a Mengele-type Nazi doctor which has become imbued with power and haunted by its victims. There is a stat line for the scalpel, and though I don't know the system, the writer seems to assume that the statline is significant enough that the PCs will want to keep it in order to wield themselves. It has a market value of 10000 nuyen.
I haven't read much more of the module, but the whole business seems incredibly tasteless, poorly concieved, very poorly written, and of limited actual in-game usefulness. Neonazi? It doesn't really jump out at me. It doesn't promote or deny the holocaust, just treats it rather blandly as a historical fact. Most players I know, however, would have SERIOUS ISSUES with having their PC running around wielding MENGELE'S FRIGGING SCALPEL, much less actually going on a shadowrun to especially to retrieve the thing...
