So if some of you are unfamiliar on how to get to the new version (still going through devolopment) you go to your Library, then right click on Unturned, then go to properties, then select the Betas tab, then for the code its OPERATIONMAPLELEAF, then click check code and you should get it, then click on the opt out all betas and select preview-public test branch, then exit and it should start downloading.

If you do not like the old unturned and want to go back, go back to the betas tab again and select opt out all betas
