Forgive the ignorance, but I went to this site http://ace.dev-heaven.net/wagn/Features and couldn't really find the answer to the questions I was wondering about:
Can I use any of the ACE weapons that can be found in the Armory in the Single Player campaign mode?
Also, if I want to try out a certain character in the Armory, is there any way to customize his weapon so that he uses any ACE weapon of my choosing?
