All Secret Black Box | Sengoku BASARA2 : Heroes (PS2)

This is a video discovering every black box appeared across maps in Sengoku BASARA2 : Heroes. There is rare stuff you could acquired when you break them and most of 'em were placed in hideous spot you would need some deep exploration because black box is so hard to find. There is 64 maps, and black box appeared only in 33 maps. i've checked deep and im pretty sure its only 33 maps with black box. So if you think i've missed please let me know in the comments below, Thank you.
