The bottom section will change with every shot, so be patient and take your time. Look to drop the outer edges to give yourself access to the V-shaped columns higher up. Once you have removed the horizontal bottom section, work up the columns until you can see the row of Rotators and Poacher Traps. Your best bet here is to try and get On Fire if you can. Either way, aim for the Rotators at each end of the row - this is the fastest way through to the top section.
