I very much agree with your assessment on berets. Way overdue!
As for minigun, I am afraid I can't be that much help, aside from knowing that they exist, and it seems that they are available in the assorted energy types.
It looks like anti-proton has a crit severity bonus.
This program, though reasonably normal at times, seems to have a strong affinity to classes belonging to the Cat 2.0 program. Questerius 2.7 will break down on occasion, resulting in garbage and nonsense messages whenever it occurs. Usually a hard reboot or pulling the plug solves the problem when that happens.

Good luck, fellow beret enthusiast! =D
And knowing is half the battle!

That said i have heard praise for these weapons:

I'll leave more specific comments to those who use/enjoy mini guns.
Edit:
If memory serves this minigun has the standard 30m range instead of the usual 25m range so this may be worth purchasing/upgrading:

Edit 2: It's 35m instead of 30/25m
