If you mix playing the levels solo and with a second controller…will you still get the achievement? Or do you have to do them all solo…or all co op? Anybody know the answer to this?
Pretty sure you can do a mix of solo and co op
If we are talking about the MCC achievements you cannot mix solo and coop. If you do one level SLASO, and the rest CLASO or vice versa, waypoint will not consider it. I did all the levels in CLASO, which is easier for most levels, but for some it is a big detriment.
