LEGO Star Wars The Force Awakens

Thanks for clarification, both of you! Can confirm it works when you select "Exit Level"

Just confirmed that you can select "Exit Level" and then "Exit Level" again to proceed without saving. Achievement popped shortly after.

I've tried Save & Quit and just Exit Level and neither one popped the achievement. Does it matter which Chewbacca you use? I don't know which one I was using.

I don't think so... this game has been showing a LOT of glitches.

Yeah, my achievement is apparently glitched. I tried with every Chewbacca trying to start/quit then eventually completed a whole mission and it won't unlock.

A number of people have said that their achievements have popped late. I didn't have that problem with a single achievement, but a lot have.

Yeah, I've considered maybe that would happen. I've only had it happen with one other game, the Halo: Master Chief Collection. A lot of achievements would pop a day or two later but I had 3-4 that took a couple of months to pop.

The quitting technique didn't work for me. However, I got it the way you're supposed to do it with no problems unlocking it.

OK, I got it to unlock finally. It didn't pop later like I expected it to. I played through another mission using Maz and Chewie (Rathtar Hunting) and for some reason it popped that time. Maybe it's because that mission doesn't require as much switching around as the previous mission I'd played with them, which was Starkiller Sabotage. I'd selected Maz at the start screen then added Chewie once the level was loaded, and whenever I had to switch to another character I always did it when I was Maz, that way Chewie never disappeared from the party.

the level actually has to end with using the characters as opposed to being in
vehicles

This one was easy on the Epilogue. Choose Chewie for the Free Play (I did just regular Chewie). Then when the level starts, switch the second character to Maz. Switch back and forth from Maz to Rey (only using Rey for the things only she can do), keeping Chewie the whole level. It worked like a charm for me, first try.

I started Epilogue with Chewie. Switched to Maz on the second character. Played for a minute and then just Exit Level -> Exit Level. First go :D

Just got this and started up the Epilogue level. Chose Maz as my main character, then chose Chewie in the level. Grabbed a few studs with both characters and quit out. Achievement popped right away, first try.

Quitting does not work

This one was really glitchy for me. It didn't unlock even after finishing the level as Maz and Chewie numerous times. It then randomly popped mid level later on. That said, it worked fine on the 360 version.

Can confirm that exiting level without saving works and it popped for me!
