NieR Automata Fastest leveling method. (Patched as of May 2017)

THIS HAS BEEN PATCHED AND NO LONGER WORKS. I'm using is an exp chip, +4 I think, and a +6 diamond combustion chip (This combustion chip will make this SO much easier at lower levels). All you have to do is go to chapter 4-1, amusement park, and kill all the enemies and then hijack a neutral unit. After that walk up to bunny statue like so and lock on to it, hack it, ?????????, profit. Quick save and reload data on the spot. Went from 60 to 99 in about an hour. Also, bunny drops frequent Machine Cores, and L parts!
