I've been recording my playthrough of the game at Infernal difficulty with a clean save (meaning no new game+), I've completed up to episode 6 but only uploaded up to episode 2: http://www.youtube.com/watch?v=bBBg1L0-QPs
I have to say, playing like this on infernal has made the game much more enjoyable for me. I actually think more about how to navigate through the ship and how to prepare for certain combat scenarios.
There was a bug/oversight where the game had some missing resolutions, but it should have be fixed in a patch now.
man, Hunk and Rachel(?) have the best maylays. Too bad I won't double dip, as I love playing this on portable with my bro. Also, in the 3DS version, after you cap out at level 50 in Raid mode, is there a way to make all monsters level to you so you can play all the levels with the appropriate challenge?
