I play this game whenever I find time to kill, one of my favourites despite its age.
I found a bug though, just wante to mention it, it seems that when ammo capacity is over 900 (nine hundred), the "Old Glory" minigun can't fire any bullet, and so, I have to see my men fight to protect the house. The others seem to work fine, the only problem comes with the minigun, maybe it has something to do with the recoil it has before firing?
