In Bayonetta for the PS3 and Xbox 360, there is an alternate method you can use to unlock accessories if you have some extra Halos.
In Chapter two after Verse 3 on any difficulty, look for the area with the phones on the plaza. You’ll see three phones total. Of the pair that are together, the one on the right is for accessories. Use the phone with enough halos to input the following codes, and you’ll unlock the accessory. Directions are all using the dpad.
