I can never defeat Black Widow II! I tried 6 or 7 times now, I watched some walkthroughs on youtube, and got some off of gamefaqs, and I can't beat him. By the time I get up to that huge machine gun, I only have 500 HP left and I get pwned in less than 30 seconds! I need some help...

I'm glad I could help you out. If you have any more questions just ask.
