How to do IZUNA DROP, HARAKIRI, GHOST KILL and the rest
Thought I would share this info,
Izuna Drop - XYXXXY
Harakiri - Lvl 25 online to unlock, press B when your close to death.
Ghost Kill - Online only, walking slowly to turn invisible, then press Y to lunge into a near enemy for an auto kill. I Think you have to be a lvl 10 or somewhere around that.
Betrayel - Online only, you have to be given the contract to do so. Then press LEFT STICK in and Y next to a team mate.
Battle Royal - This is random, keep playing matches until a contract hits turning the game into Free For All, actually happens often. Then you have to win.
These are the confusing ones, hope this helps
