SPG

good day all, here is a question that might seem dumb but i really have no idea what it means, some modified saves that i downloaded explains that you
should do the spg thing while game is loading etc.. can anyone tell me or explain to me what this means please.

SPG stands for second profile glitch its where you use two controllers to unlock the achievements i never done it myself so i cant help you on this one maybe some one will come along and explain in more detail

helllo i did try useing spg but fine since the xbox update it dose not work since you need passwords to log on the other controler and no one seams to know them
