Besides, you only really deserve the achievement if you complete everything anyways.
If you don't A+ every level on top of 100% completion, you're also not for real.
:P THE HATE!
I bet ya also gotta be in the top 100 at every level and be able to play all stages blindfolded to deserve it. btw, got meat ninja now and mr minecraft. Thanks to the ppl who posted the correct awnser, 105,5% was the requirement for meat ninja.
