I need 3 people for one last level in the game. I think you need to have completed the entire story mode to help me.
Add me if you want to help... my PSN username is: dinorap1

I would, but I have the PS3 version.

I'm up for this too but as far as I know the game still refuses to connect to other players.

Oh, I think I figured out a way to connect to other players. You actually have to Share Play with the other person, and then invite them into your game.
It's pretty silly how complicated it is... I hope they fix it so you can Dive In like the other games.

Joining players works flawlessly on PS3. I think that LBP3 was being developed and optimized for the PS3 longer than it was for the PS4. They might have possibly been developing it anticipating a PS3-only release, then the PS4 was announced, so they rushed to port the game to it and release it on time with PS3. Both games are still flops, though.

Well, hopefully they'll fix it soon. It's too bad the PS4 version has so many issues. This game would be awesome otherwise...
