To continue the campaign after getting to the lobby looking thing, go in to all of the minigames and go out, you dont have to play them but you can if you want, after this go up the stairs to the left of the bodymall and use the crane to lift the orbs with lights coming from them up from the area of the minigames and bring them to the pipes on the left and right of you. after this you should be able to continue with the large metal door in the corner of the map. I hope this helps atleast someone, if it did help possibly give an award if you are feeling extra nice? Have a good day!
