If you are looking for something to deflect Odd-Jobs hat in the secret base you should get out of the prison area, with help from Zhong Mae & go to the end of the hallway then go up (it's easier if you use your rocket launcher). Look around, there should be a room with four men & 1 or 2 boxes. Destroy one guy & the next will take more shots to beat - he will drop a box, after he's gone take it & you'll have the titanium shield. Use it to deflct Odd-Jobs hat & send the hats back at him to win.
