Thanks for the plug, Cory. The Mummy Mordheim group was originally supposed to be based on Mordheim (hence the name), but we ended up using LotOW with a couple of variant rules. The group has been defunct for a couple of years now, but you can still dig out some of the rules that Dan and I developed, as well as a couple of game reports. We developed the rules before "Showdown" came out, so there are some differences between our ideas and the ones that were published by GW. Hope you find them of some use.
Kind regards
Will
