Sachys: Did you actually play as far as the boss fight on the rooftop after the flying sequence? - Near impossible with KB+M!
DyNaer: i beaten this boss, but granted it was a nightmare o_o , i would say it was the harder part of the game for me (even with a xbox360 controller); so i won't imagine with a kb+m
it was horrible and made me stop playing the game. the colonel managed to get through it somehow - but also agreed how ridiculous it was.
thankfully i now have a controller, so next time im in the mood for some evil boss action...
Edit: Dark Souls was far easier with KB+M
