Hi Yankee!
I finished playing Medal of Honor, very easy, and now I am playing Wolfenstein that I had not played when it came out, apart from some stealth soldiers than more often than not kill me, up to now it is also easy.
It seems that the boss battle in the Vanquish Demo is the same you describe. I may buy when it goes down in price a lot. As far as I know not many people are playing it. I have Demon Souls, have not been playing it a lot, I find frustrating the way one "reincarnates" and I am much better with guns than swords.
Resistance was difficult with some of the big bosses, also I played it when I was quite new in consoles.
