Dînadan:
The sample/starter rules for Mantic’s 40k equivalent are now up on their website:
http://www.manticgames.com/free-rules.html
There are two versions, Firefight which is equivalent to 40k in that armies consist of units comprised of individual minis in a skirmish formation, and Warpath is a larger scale version with units comprised of bases, each of which contains a set number of models (although like in KoW the number of minis on the base doesn’t represent an exact one-to-one and are more there to look nice with the base as a whole being what matters; bases are removed as whole rather than individual minis).
