I know Modiphius and Spartan are working on a forthcoming A!C skirmish game, but I've recently been getting heavily into Warlord's Bolt Action, and I've been working on a conversion of units and creatures from A!C to that ruleset. Here is the first draft:
Bolt Achtung! – An Unofficial Achtung! Cthulhu Supplement for Bolt Action (PDF, 130K)
I should stress that this is very much a first draft. I haven’t done any playtesting yet and things like points values are just guestimates at this stage. Any comments and criticism would be gratefully received.
