There are 2 English guides to unlock all the achievements, but I'm still unsure until I complete the level "Reactor".

To unlock the level "Reactor", you need to complete all the levels from World 1 to World 4. I don't have the screenshot on it but someone uploaded the shot.

Don't unlock Shade, or you have to create another profile to unlock this achievement.

After the completion of "Reactor", you'll have an access to World 6 "Basement" and unlocking Clobber.



You can play these levels without Shade, the walkthru videos work without glitch.


There are 21 levels without Shade in World 6 "Basement". You'll find the Boss after completion of all these levels without Shade.

Killing the Boss is quite easy and the datasphere in Boss Office is easy to get.

I'm not the first one to upload screenshots on this issue, and this guide is for those achievement hunters.

If you get "We Don't Need Another Hero" first, then you need to play World 7 "The Boss Office" again after completing World 6 "Basement" to unlock all the achievement including "Platypus".
