been watching alot of Ninja Gaiden 4 footage lately, and while there is alot of stuff they're bringing back that's cool (UT's, Obliterations, Essence), I can say with confidence that I don't like the UI, call me a purist if you must but offscreen enemy indicators and Spidey Sense style warnings for incoming attacks don't belong in Ninja Gaiden, fingers crossed we can turn that stuff off
Very likely that even if it was done in-house you probably would of still seen it lol.
