I really love the Achtung! Cthulhu setting for Call of Cthulhu from Modiphius Press. It’s also for Savage Worlds (using Realms of Cthulhu), but I started into the mythos through the original game and it just doesn’t feel like Cthulhu to me unless I’m rolling percentile dice.
Modiphius has put out two amazing long-term campaigns (Shadows of Atlantis, which I’m currently running, and Assault on the Mountains of Madness which is eagerly awaiting a chance at the table) as well as a series of short scenarios that can be part of a linked campaign or stand-alone. Already looking to expand the options, however, I went through other published Call of Cthulhu scenarios looking for scenarios that you could easily use for an Achtung! Cthulhu game.
