Oh, and I found the windmill shurikens at last.

I think I know what FacilityPro meant when he said at first he didn't even know if he was doing the right thing.

First, you get a clue by shuriken that a powerful weapon is hidden in the city, and that only a ninja can reach it. Having heard of the WS, I surmised that must have been what that refered to. I checked my map, and noticed a little alley way in that area that didn't seem to serve a purpose. So, I guessed the WS were hidden there.

The alley, according to the map, had two little rectangular areas off of it. At first, I kept trying to run around one of them, to do the continuous wall run jump move. Sometimes it seemed like it might work, but not very well.

Eventually, I left the alley and was wondering if I could continuous wall run jump along the alley walls. I tried that a couple of times earlier, but it didn't seem to work. For one thing, there was a rain gutter that blocked one wall.

But on the way out, I noticed there were some thick horizontal areas demarcated by thin blue or green lines. I earlier got a clue that said something about looking for blue to find the path. The first of those stripes looked to me like it was on a wall that was actually outside of the alley, but led into it.

Anyway, starting from there I was able to make the jumps to reach the shurikens. Also, there was a cameo there in the form of an Xbox logo.
