@Caesar-Seriona They will work with most versions of A&A.
The issue will be that Anniversary and Global have more territories on the map than1942 2ed.
Some have suggested using a die to decide. (if 1942 has one territory but the other has three, 1-2, 3-4, 5-6 die roll to see who gets the zombies)
You might run short of zombies as well, but painting up some infantry from a parts game should work well.
I don’t think anything else is needed.
