Plenty of historical examples of the quad 20mm flakvierling being used with excellent effectiveness against ground targets, but it doesn't appear in the game (and the sdkfz 10/4 single-barrel 20mm that is available in the game is a bit anemic). Has anyone built a flakvierling, or better yet the flakvierling mounted on the armored sdkfz 9?
Thanks

How about modifying Flakpanzer IV "Wirbelwind I has the 4 guns if you are looking for that I know I have seen them in BA games not sure about BA2. Of course it is a tracked vehicle but that may give you the gun portion.

I read in an article that the Wirbelwind with 4 20mm was later upgraded by to a single 37mm due to best Anti-Air effectiveness but do not remember where I read article.

here is the weapon of which you speak, a quad 2cm as requested...
