Unlock all Characters for Year one edition after 10 sec.
Same concept on Easy Hero Unlocker by BIZ
http://www.nexusmods.com/stateofdecay/mods/21/?

Done by comparings XML on Easy Hero Unlocker by BIZ and Breakdown YOSE easy hero challenges by cunhak9

Installation:
Copy-paste the contents of the zip file to the game directory (fresh installed game, no mods for to avoid conflict).
Run game. Hit new game. Run around until a pop up message appears on the lower right of the screen. When finish, Save and quit. Done.

Enjoy:]

Made this mod to be used  by a friend, and heck why not share in here too.
I'm not playing the game and can't update this mod if State of decay YOSE will have an update in the future (Who knows?).
If you want to edit the files yourself, please do. No need for permissions.
