Improvised Nubby DS4 v1.1

Use the right stick to aim Nubby, and R2 to fire. R1 will jumble the board, and the touchpad will allow you to cleanly scroll across your item bar to check items or rearrange them. The left stick and the Cross button allow you to move the mouse and click in the game's less-friendly shops and menus. My recommendation is that when you intend to buy an item, hover over it with the left stick, press and hold Cross, and then use the touchpad to determine which item slot you want to place it in.
