Yeah, would really like to see this. We had a lot of fun with Showdown back in the day and I like the whole Achtung! Cthulhu thing.
The rate of releases for Modiphius has been slow (successful Kickstarter blues?), but steady. I didn't pledge but I've picked up several of the Achtung! Cthulhu titles as they hit Drive-Thru RPG.
My impression of the Modiphius products is generally good. Some typos and unfortunate inconsistencies with information and stats in their multi-system books, but the content makes up for it.
We ran the 'Three Kings' Call of Cthulhu adventure last spring and it was great fun.
