Hello, I am looking to run an Achtung! Cthulhu 2d20 game and thinking of using FG for it.

Figure that Nerd Eye Industries will be doing an official ruleset at some point as they are doing so for the other 2d20 Modiphius games. Did asks over on their forums but still no reply.

In the meantime, is there any existing rulesets/extensions I should concern using? Do not want to bother make my own if something already exists. Think that MoreCore has lot of the things I would need already in it and could build from there.
