Golden Abyss also used the NGP's accelerometer (or as some devs surprisingly referred to it, "SIXAXIS controls") in a number of ways. In the first example I was tilting the entire unit in a single direction to make Drake lean out and reach towards a ledge when platforming. The second time I was able to use it was in a firefight when using a sniper's scope. Instead of controlling the reticle like in a traditional shooter, I had to move the entire NGP unit to aim at my target. I personally didn't find any of this motion stuff to my liking, particularly this sniper targeting -- I was quickly reminded of the ill-conceived forced flight controls in Lair. Fortunately, like other gesture- and touch-based controls I encountered, I'm told
this is entirely optional and can be disregarded or turned off altogether.
