Posted yesterday at 20:41, Edited yesterday at 20:42 by CyclonicGlitchTrying to figure out if I need 4 controller before starting this game. I think it can be done online but I am not sure.
Posted today at 00:15The second solution on the achievement seems to say it's possible. I didn't, I used a Rock Band drum kit and guitar with 2 controllers. I'm more than willing to help to see if it's possible.
